+# Chameleon Ultra Contribution guidelines
+
+Any and all contributions are welcome!
+
+Heres a bit of info and a few guidelines to get you started:
+
+- General
+    - Avoid force pushes. Force pushes and "one commit" PRs not only make reviewing more annoying but also erase a significant part of the git history. This, among other things, makes future debugging and bisection a lot harder.
+    - Conventional commits. It is recommended to follow the [conventional commit](https://www.conventionalcommits.org/en/v1.0.0/) pattern when it comes to commit messages. While this is not strictly enforced, its highly recommended and a good habbit.
+    - Atomic PRs. To help keep an overview and avoid conflicts, it is highly encouraged to file Atomic PRs. Atomic PRs are:
+        - Focused Scope: It targets a single, well-defined change, making it easier to understand and review.
+        - Minimal Size: It contains only the necessary code modifications to achieve its goal, avoiding unrelated changes.
+        - Independent: It should be able to stand on its own without depending on other unmerged PRs, reviewed, and merged independently.
+        - Self-Tested: each PR should include an appropriate set of unit tests that tests the changes. (optional but highly appreciated)
+    - Atomic Commits. Similar thing as atomic PRs. When you are done with a feature, commit. Made a working change? commit. Git commits are basically free. Doing frequent commits at sensible points throughout development not only helps you keep track of progress but also saves progress and changes so you can revert when something goes wrong. It also helps when debugging and bisecting as more granular commits allow for easier issue location.
+
+- CLI
+    - The recommended packagemanager is [UV](https://docs.astral.sh/uv/) (from astralsh). You may use the manager of your choice, but when adding new dependencies they must be added to the UV lock file and pyproject toml as well.
+    - Type safety is important. The CLI should be typesafe. Python 3.9+ offer a wide variety of type declarations. Metas [pyrefly](https://pyrefly.org/) is used to do type validation. It is recommended to install the appropriate vscode extension and check your types before opening a PR.
+    - Formatting matters. Mostly. While pixelpeeping and exact rules are annoying and unnescesary, format your code in a readable and logical way. [Ruff](https://docs.astral.sh/ruff/) is used to enforce various formatting rules. You may install the Ruff vscode extension or use the CLI to format before opening a PR.
+    - Avoid extra packages. Almost everyone knows the "meme" of the javascript ["is-even"](https://www.npmjs.com/package/is-even) package. While it is encouraged and makes sense to use packages where appropriate, just installing packages for the hell of it even if its a 2 liner is not sensible.

-- the *Connected Port*: it tells you where and how the chameleon is connected, followed by how it is connected (*Connection Method*), which displays a USB or Bluetooth icon ;
-- the *Battery Charge* icon: you can press it long to get more details. Note that it is refreshed only when reopening the Homepage ;
-- the *Used Slots*: it displays how many out of the 8 slots are used ;
-- the *Slot Changer*: the currently selected slot is highlighted with a red circle, while enabled slots are filled in. Everything else is a hollow circle. The arrows left and right allow you to change the currently selected slot ;
-- the *Firmware version*: the version is pulled from the device displayed, as well as git commit information ;
-- the *Check for updates* button: it compares the firmware with the one available on GitHub and then updates if a newer version is available ;
-- the *Switch mode* button: use it to switch between reader and emulator modes. The icon will update accordingly ;
-- the *Device Setting* button: it allows you to change settings concerning the device, like changing the animation mode.

-![Device Settings2](./images/cugui-devicesettings2.png)
-
-Top to bottom:
-- *Enter DFU mode*: to enter the device DFU mode. Allows the user to take over ;
-- *Flash latest FW via DFU*: download the newest firmware from GitHub, disregarding if the device is already up to date, and flash it ;
-- *Flash .zip FW via DFU*: it allows the user to select a zip they would like to flash to the device ;
-- *Animations*: choose if the device should play the boot-up animation when woken up by an external RFID field ;
-- *Button config*: it allows you to define both short-press and long-press actions
-- *BLE pairing* toggle: you can decide whether pairing with a BLE PIN is required or not. Enabling PIN increases security at the loss of convenience. You can define a *BLE PIN* once pairing is enabled and you can force forgetting about existing pairings with the *Clear bounded devices* option.
-- *Reset settings*: it resets all device settings but does not wipe user data.
-- *Factory reset*: **IT WIPES ALL USER DATA** and resets the device to factory settings.
-
-### Slot Manager
-![Slot Manager](./images/cugui-slotmanager.png)
-
-The *Slot Manager* consists of 8 cards representing the 8 slots on the device.
-
-The *RFID icon* in the top left corner can either be green or red, meaning the slot is enabled and disabled respectively.
-
-The *Credit Card icon* displays the name and card type of the HF card in the slot.
-The *Wi-Fi icon*, on the other hand, displays the name and card type of the LF card in the slot.
-
-The *Gear icon* opens the slot settings. These settings can be changed per slot.
-
-The entire card is also one big button, pressing anywhere on the card opens the select dialog for loading a card.
-
-### Slot Settings
-![Slotsettings](./images/cugui-slotsettings1.png)
-![Slotsettings2](./images/cugui-slotsettings2.png)
-
-The two rows at the top, labeled HF and LF respectively, display the names of the currently loaded cards. Next to them, the *X* clears them out of the slot. If both are empty, the slot will automatically be disabled.
-
-Under *Slot Status* you can set if the slot is enabled or disabled.
-
-The *Mifare Classic emulator settings* section allows you to toggle various behaviors:
-- *Gen1A Magic Mode*: behaves like a gen1a magic card and allows writing to it using magic commands like the Proxmark3 `cload` ;
-- *Gen2 Magic Mode*: behaves like a gen2 magic card, makes Block 0 writable ;
-- *Use UID/SAK/ATQA from 0 block*: the Chameleon Ultra stores the UID and other anti-collision data independently of the card content. Enabling this setting tells the Chameleon to derive them from card content block 0. Only for MFC with 4-byte UID ;
-- *Collect nonces (Mfkey32)*: it toggles nonce collection for mfkey32. When enabled you will be prompted to present the Chameleon to a reader. After you have collected nonces the *Present Chameleon to reader* message will change into a *Recover Keys from x nonces* button. Pressing this will start the recovery process ;
-- *Write mode*: Please refer to the [firmware docs](./firmware.md).
-
-### Search dialog
-![Search Dialog](./images/cugui-searchdialog.png)
-
-When using the GUI you may encounter a *Search* dialog. The dialog is structured as follows:
-
-Top left you find the *Back* button, this will abort the selection and bring you back.
-
-Near the end of the row, if it is a card search dialog, a filter option will show. This allows you to filter between *HF*, *LF* and *All* cards.
-
-At the end you find a *X*, this X will clear the query.
-
-You enter the query into the *textbox* on the top with the placeholder text "Search"
-
-The search results get listed below. The Card or Wi-Fi symbol indicates if it is LF/HF. The color of the Icon is the user-defined color.
-
-Listed also are the name and type.
-
-Selecting the entry automatically closes the search.
-
-### Saved Cards
-![Saved Cards](./images/cugui-savedcards.png)
-
-The *Saved Cards* page allows you to manage your cards and dictionaries.
-
-You import a card or dictionary by clicking the *+* button in their respective half. This opens a select dialog. You may then either select a CUGUI Json file or a Bin file. A Json file gets imported immediately while a Bin file asks if the supplied data is correct before saving.
-
-Once again, we got a card per card or dictionary. At the left you find the Icon for HF/LF with the user-defined color. To the left of that the card name, type and quick actions for edit, export and delete.
-
-The Card is again one Big button, pressing it brings up the Slot info. It displays info about the selected item and also has the quick actions present at the bottom.
-
-![Card Info](./images/cugui-savedcardinfo.png)
-
-### Card Edit Menu
-![HF Card edit](./images/cugui-editcard-HF.png)
-![LF Card edit](./images/cugui-editcard-LF.png)
-
-Depending on the selected card type the menu only displays options applicable to it.
-At the top of the menu is the name and icon. Pressing on the icon allows you to change the color.
-
-Right below is the drop-down for the type. You may switch between any type at will.
-
-A bit lower again you find the UID, SAK, ATQA, ATS and all other options for the selected type. This form auto-validates, so you should not be able to save a invalid config.
-
-And finally at the bottom are the save and cancel options, to save the changes and exits, or to cancel the operation with no changes.
-
-### Settings
-![Settings](./images/cugui-settings.png)
-
-The App settings have their own page and consist of a few simple settings:
-- *Sidebar Expansion*: Whether or not the sidebar shall be expanded or if the windows size should decide that
-- *Theme*: Light/Dark or get it from the System
-- *Color Scheme*: Allows you to choose a color you like for the app
-- *Language*: Choose any of the languages available. Translating is done via our Crowding project.
-- *About*: Displays simple info about the app, such as build number, contributors and people who have donated on Opencollective
-- *Activate debug mode*: Don't, just Don't
-
-## How to use MFKEY32
-
-- set slot to MIFARE Classic (by uploading an empty dump)
-- enable mfkey32 for that slot (toggle in slot settings)
-- select slot and present ultra repeatedly to the reader in order to collect nonces
-- after collecting some nonces, go back into slot settings and click recover keys
-
-## Troubleshooting
-
-### Font scaling issues on HiDPI screens
-
-If you have font scaling issues (tiny fonts) with the Linux desktop app and a HiDPI screen, you can solve it by running the app as
-```
-GDK_SCALE=2 GDK_DPI_SCALE=0.5 /usr/local/lib/chameleonultragui/chameleonultragui
-```
-
-### Key recovery from this card is not yet supported
-This error may occur when the card you are trying to recovery keys from is requiring a not yet supported recovery technology. You cannot tell the required recovery method from the outside.
-
-You may be able to solve this issue by dumping the card with a Proxmark3 or Mifare Classic Tool (Mobile App) and then importing a bin file.
-
-### Error: Invalid data length
-This error may occur on windows devices and seems to be a deeper bug in the serial library.
-
-Reconnecting the device may solve it, also make sure that the App and Firmware are up to date.

-# CLI
-
-The CLI (**C**ommand **L**ine **I**nterface) is the official way to control your Chameleon.
-
-It requires at least **Python 3.9** version.
-
-## Installing
-
-There are multiple ways to install the CLI, depending on your OS.
-
-### Windows
-
-Windows users have the choice of 4 options:
-
-#### ProxSpace
-
-Using ProxSpace to build the CLI is the easiest and most comfortable way to get started.
-
-1. Download ProxSpace from the [official GitHub](https://github.com/Gator96100/ProxSpace/releases/latest)

-deactivate
-```
-
-### MacOS
-
-*Coming Soon*
-
-## Usage
-
-When in the CLI, plug in your Chameleon and connect with `hw connect`. If autodetection fails, get the Serial Port used by your Chameleon and run `hw connect -p COM11` (Replace `COM11` with your serial port, on Linux it may be `/dev/ttyACM0`)
-
-### MFKEY32v2 walk-through
-Make sure to be in the `software/` directory and run the Python CLI from there.
-
-```sh
-# Connect to the CLI
-hw connect
-# Check which slot can be used
-hw slot list
-# Change the slot type, here using slot 8 for a MFC 1k emulation
-hw slot type -s 8 -t MIFARE_1024
-# Init the slot content
-hw slot init -s 8 -t MIFARE_1024
-# or load an existing dump and set UID and anticollision data,
-# cf 'hf mf eload' and 'hf mf econfig'
-# Enable the slot
-hw slot enable -s 8 --hf
-# Change to the new slot
-hw slot change -s 8
-# Activate the authentication logs
-hf mf econfig --enable-log
-```
-Now disconnect, go to a reader and swipe it a few times
-
-Come back
-
-```sh
-# connect to the CLI
-hw connect
-# See if nonces were collected. We need 2 nonces per key to recover
-hf mf elog
-# Recover the key(s) based on the collected nonces
-hf mf elog --decrypt
-# Clean the logged detection nonces
-hf mf econfig --disable-log
-```
-  Output example:
-```
- - MF1 detection log count = 6, start download.
- - Download done (144bytes), start parse and decrypt
- - Detection log for uid [DEADBEEF]
-  > Block 0 detect log decrypting...
-  > Block 1 detect log decrypting...
-  > Result ---------------------------
-  > Block 0, A key result: ['a0a1a2a3a4a5', 'aabbccddeeff']
-  > Block 1, A key result: ['010203040506']
-
-```

-# Development
-
-In this file you can look up how to [install requirements](#Prerequisites-for-compiling), [edit](#Editing-the-code), [compile](#Compiling-the-code) and [debug](#Debugging-the-code) the firmware!
-
-## Prerequisites for compiling
-
-### install a cross-compiler
-
-So far, the following compilers have been reported to work fine.  
-Download one of them and decompress it.  
-Remember the path where you installed it.
-
-- [gcc-arm-none-eabi-10.3-2021.10](https://developer.arm.com/downloads/-/gnu-rm)
-- [arm-gnu-toolchain-12.2.rel1-XXX-arm-none-eabi](https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads), e.g. [arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi.tar.xz](https://developer.arm.com/-/media/Files/downloads/gnu/12.2.rel1/binrel/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi.tar.xz) for a x86_64 Linux host
-
-Always use the official versions from ARM, *DO NOT* install `gcc-arm-none-eabi` from Debian/Ubuntu.  
-For some unknown reasons, same gcc version from Debian creates a bootloader too large to fit in the allocated flash space.  
-Moreover it does not contain the `gdb` debugger.
-
-### install make
-
-* **Debian/Ubuntu alike**
-  * Open a terminal.
-  * Run the following command to install Make: `sudo apt-get install build-essential`
-* **Windows using Chocolatey:**
-  * Open a PowerShell terminal with administrator privileges.
-  * If not yet installed, run the following command to install Chocolatey:
-    ``` Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1')) ```
-  * In the same PowerShell terminal, run the following command to install Make using Chocolatey: `choco install make`
-* **macOS:**
-  * Open a terminal.
-  * If not yet installed, install Homebrew package manager by running the following command: `/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"`
-  * Once Homebrew is installed, run the following command to install Make: `brew install make`
-
-### install nRF tools
-
-- Install nRF Util tool [nrfutil](https://www.nordicsemi.com/Products/Development-tools/nrf-util)
-  - Move it to a known path like `C:\nrfutil\` or `/usr/local/bin/`
-  - Add this path to the `PATH` Environment Variable if not yet there.
-- Install nRF Util packages:
-  - `nrfutil install completion device nrf5sdk-tools trace`
-- Install [nRF Command Line Tools](https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download) to get `nrfjprog`, `mergehex` etc.
-
-### install programmer tools
-
-Depending on the hardware programmer you want to use, additional tools are needed.
-
-- If you are using a J-Link:
-  
-  - Install [Segger J-Link Software](https://www.segger.com/downloads/jlink)
-  - alternatively, you can use openocd as described below
-  - Note: a JLink OB (or a STLink reflashed as a JLink OB) will not work on a nRF.
-
-- If you are using a ST-Link V2:
-  
-  - Install [openocd](https://openocd.org/pages/getting-openocd.html)
-  - If under Windows, install [ST-Link drivers](https://www.st.com/en/development-tools/stsw-link009.html), extract the zip and run `dpinst_amd64.exe`
-
-### configure the project
-
-- Edit `Makefile.defs`:
-  - Change `GNU_INSTALL_ROOT` (path of previously installed Compiler `bin` folder)
-  - Change `GNU_VERSION` (Version of the installed Compiler) (FIXME: is it really used?)
-  - Change the other paths to match your system if needed
-  - Don't forget to remove the `#` in front of the changed lines
-- Alternatively, if you are committing often code, it may be easier to leave `Makefile.defs` intact and to invoke `make` with the desired variables from a script, e.g. `make GNU_INSTALL_ROOT=../../../arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/bin/`
-
-## Editing the code
-
-You can use [Visual Studio Code](https://code.visualstudio.com/download) to edit this project! Simply download and
-install it!
-
-- Install the [C++ Extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools) in VS-Code.
-- Install
-  the [C++ Extension Pack](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools-extension-pack) in
-  VS-Code.
-- Create a new IntelliSense Configuration:
-  - press F1 in VS-Code and enter `C/C++: Edit Configurations (UI)`
-  - Add a new Configuration and name it
-  - Specify your Compiler path (path of previously installed Compiler `bin` folder)
-  - Change IntelliSense mode to `gcc-arm (legacy)`
-  - Add include path `${workspaceFolder}/**`
-
-## Compiling the code
-
-- Install prerequisites (for instructions have a look at [Prerequisites for compiling](#Prerequisites-for-compiling))
-- Run `build.sh` or try to execute its steps manually if your platform is not yet properly supported. Feedback is always welcome.
-
-The script produces several images in `objects`.
-
-* `fullimage.hex` to be used with a programmer over the SWD pins
-* `dfu-app.zip` and `dfu-full.zip` to be used with DFU mode
-
-## Uploading the code in DFU mode
-
-If the bootloader and the SoftDevice are already properly installed on the Chameleon, you can reflash it directly over DFU.
-
-To set the device in DFU mode:
-
-* you can use the Python client and issue the command `hw dfu`
-* you can use the script `resource/tools/enter_dfu.py` that does exactly the same but may be easier to call from your scripts
-* you can unplug the device, wait for it to sleep, then press the button B and plug it. If the application is bogus, this is the only way.
-
-The LEDs 4 & 5 should blink green when in DFU mode.
-
-To flash only the application (safer):
-
-`nrfutil device program --firmware objects/dfu-app.zip --traits nordicDfu`
-
-To flash everything (be sure to also have a JLink or ST-Link V2 programmer if something goes wrong):
-
-`nrfutil device program --firmware objects/dfu-full.zip --traits nordicDfu`
-
-Under Linux you can use the scripts `flash-dfu-app.sh` and `flash-dfu-full.sh`, they will put the device in DFU mode and flash it.
-
-## Uploading the code with a programmer
-
-Connect pins GND, SWC (swclk) and SWD (swdio) to your programmer.
-
-With a JLink and `nrfjprog`
-
-```
-# application only:
-nrfjprog -f nrf52 --program objects/application.hex --sectorerase --verify --reset
-# full:
-nrfjprog -f nrf52 --program objects/fullimage.hex --sectorerase --verify --reset
-```
-
-With a JLink and `openocd`
-
-```
-# application only:
-openocd -f interface/jlink.cfg -f target/nrf52.cfg -c "program objects/application.hex verify reset ; shutdown"
-# full:
-openocd -f interface/jlink.cfg -f target/nrf52.cfg -c "program objects/fullimage.hex verify reset ; shutdown"
-```
-
-With a ST-Link V2 and `openocd`
-
-```
-# application only:
-openocd -f interface/stlink.cfg -f target/nrf52.cfg -c "program objects/application.hex verify reset ; shutdown"
-# full:
-openocd -f interface/stlink.cfg -f target/nrf52.cfg -c "program objects/fullimage.hex verify reset ; shutdown"
-```
-
-## Uploading the code over BLE
-
-If you are adventurous it is possible to flash the device over BLE (DFU mode).
-
-To put the device in DFU mode
-
-* you can use the Python client and issue the command `hw dfu` **TODO:** this will be possible only when the client will be able to work over BLE...
-* you can use the script `resource/tools/enter_dfu_over_ble.py`
-
-Once in DFU mode, the device will announce itself over BLE as `CU-xxxx` where xxxx are the last 2 bytes of the Device Serial Number.
-
-Then use the official [nRF Device Firmware Update](https://www.nordicsemi.com/Products/Development-tools/nRF-Device-Firmware-Update) mobile application to flash one of the DFU images.
-
-## Debugging the code from VSCode
-
-- Install [Cortex-Debug](https://marketplace.visualstudio.com/items?itemName=marus25.cortex-debug) VS-Code Extension
-- Open `app_main.c`
-- Open the extension with `CTRL-SHIFT-D`
-- Klick on `create a launch.json file`
-- Select `Cortex-Debug`
-- Add this in the configuration bracket:
-
-```

-}
-```
-
-- To change `executable` target in `launch.json` to `application` or `bootloader`
-- In the debug menu you can select `Debug with JLink` or `Debug with STLink`
-
-## Debugging the code with gdb and openocd
-
-See first if you can execute `arm-none-eabi-gdb` from the installed tools.
-
-* gcc-arm-none-eabi-10.3-2021.10 gdb requires `libncurses5`
-* arm-gnu-toolchain-12.2.rel1 gdb requires Python 3.8
-
-In case Python 3.8 is not available anymore on your distro, to install a local copy you can do
-
-```
-wget https://www.python.org/ftp/python/3.8.17/Python-3.8.17.tgz

-## BlackMagicProbe with RTT support, out of a ST-Link V2
-
-You can reflash a ST-Link V2 to use it as a BlackMagicProbe, to get support for RTT and see NRF_LOG messages.
-Some clones have only 64kb, this is too short.
-Even 128kb is too small when enabling RTT, but we can comment parts of the BMP source code.
-
-```
-git clone --recursive git@github.com:blackmagic-debug/stlink-tool.git
-( cd stlink-tool && make )
-```
-
-Then put the `stlink-tool` binary in your path.
-
-Get [BMP full sources](https://github.com/blackmagic-debug/blackmagic/releases)
-
-Comment out all probes except Nordic nrf51 in `src/target/cortexm.c` big switch for probes. It should remain
-
-```c
-    switch (t->designer_code) {
-    case JEP106_MANUFACTURER_NORDIC:
-        PROBE(nrf51_probe);
-        break;
-    }
-```
-
-```
-make -j PROBE_HOST=stlink ST_BOOTLOADER=1 ENABLE_RTT=1
-```
-
-Then flash the ST_Link V2
-
-```
-stlink-tool src/blackmagic.bin
-```
-
-See [src/platforms/stlink/README.md](https://github.com/blackmagic-debug/blackmagic/blob/main/src/platforms/stlink/README.md) for more details.
-Unplug/plug.  
-Every time you plug the ST-Link, you have to run `stlink-tool` to enable BMP.  
-Under linux, it is convenient to install [udev rules](https://github.com/blackmagic-debug/blackmagic/blob/main/driver/README.md#99-blackmagic-plugdevrules) to get aliases `/dev/ttyBmpGdb` and `/dev/ttyBmpTarg`.
-
-Note that using a native ST-Link V2 with BlackMagicProbe "hosted" will not allow to see NRF_LOG messages.
-
-## Debugging the code with gdb and BMP with RTT to monitor NRF_LOG
-
-Assuming you have a BlackMagicProbe with RTT support made out of a ST-Link V2.
-
-RTT usage: https://black-magic.org/usage/rtt.html
-
-```
-stlink-tool
-sleep 1
-screen /dev/ttyBmpTarg
-```
-
-In another terminal
-
-```
-$ arm-none-eabi-gdb
-(gdb) target extended-remote /dev/ttyBmpGdb
-(gdb) monitor swdp_scan
- 1      Nordic nRF52 M4
- 2      Nordic nRF52 Access Port.
-(gdb) attach 1
-(gdb) monitor rtt
-```
-
-We are now able to use gdb and see the NRF_LOG messages on the other terminal.
-
-## Using JLink with RTT to monitor NRF_LOG
-
-cf https://embeddedexplorer.com/nrf52-nrf-log-tutorial/
-
-```
-JLinkExe -if SWD -device nrf52 -speed 4000 -autoconnect 1
-```
-
-in a second terminal:
-
-```
-JLinkRTTClient
-```
-
-## Using SWO pin as UART to monitor NRF_LOG
-
-One can set `NRF_LOG_UART_ON_SWO_ENABLED := 1` in `Makefile.defs` to activate this functionality.
-When activated, NRF_LOG will be available if one connects a UART bridge to the SWO pin which will work as a UART TX pin.
-UART works at 115200 bauds. E.g. one can use a FTDI dongle and `screen /dev/ttyUSB0 115200`.
-Contrary to RTT that needs to be activated by a JTAG probe, UART logs are immediately available.
-
-Limitations:
-
-* SWO pin is shared with... SWO so when e.g. reflashing the device, garbage may appear on the monitoring terminal.
-* SWO pin is also shared with the blue channel of the RGB slot LEDs, so faint blue may appear briefly when logs are sent and LED might not work properly when supposed to be blue.

-# Firmware
-
-The Chameleon flash contains several parts: the bootloader and its settings, the application, the user data and the SoftDevice.
-
-NOTE: If you are a developer searching for the building instructions, look into [development](./development.md)
-
-## The Bootloader
-
-The bootloader is the lowest-level program running on your Chameleon. It is read-only and provides the DFU (**D**evice **F**irmware **U**pgrade) mode. The bootloader being read-only, it makes it really hard to brick your Chameleon. The flash also contains a special section to store bootloader settings required by the nRF to deal with upgrades. This is only a concern for developers.
-
-
-You enter DFU mode by of the following methods:
-
-1. Physical button
-
-- Disconnect the Chameleon and wait for it to enter sleep mode
-- Hold down the 🅑 button. If you are using Windows you have to wait about ~5s before next step.
-- Plug USB into a PC while still holding the button. If you are using Windows you have to wait about ~10s before next step.
-- Then release the 🅑 button
-
-2. From CLI
-
-- Execute the command `hw dfu`
-
-3. From GUI
-
-- Click on `Enter DFU mode`
-
-4. From Shell
-
-- Execute the script `resource/tools/enter_dfu.py`
-
-The device stays in DFU mode for ~30s.
-While in DFU mode waiting for the update, the LEDs 4 and 5 blink alternatively green 🟢🟢.
-You can then perform firmware upgrades either via a GUI or the command line:
-
-1. Download nRF Util from the [nRF website](https://www.nordicsemi.com/Products/Development-tools/nrf-util)
-
-2. Open a Command Line / Terminal on your PC
-
-3. Install the "device" toolkit by running `nrfutil install device`
-
-4. Download the Chameleon firmware from [GitHub](https://github.com/RfidResearchGroup/ChameleonUltra/releases). At the moment it is better to take the *Development release* but beware bugs can occur. Choose `ultra-dfu-app.zip` for the Ultra or the Devkit, and `lite-dfu-app.zip` for the Lite.
-
-5. Put your Chameleon into DFU mode and install the firmware with the following command: `nrfutil device program --firmware ultra-dfu-app.zip --traits nordicDfu` (keep in mind to change the filename if you are using a Lite).
-
-Step 5: Alternatively you can connect the Chameleon over USB and use the script `firmware/flash-dfu-app.sh` which will take care of flipping it into DFU mode and flashing it with the adequate firmware.
-
-While flashing firmware is in progress, the LEDs 4 and 5 should blink fast blue 🔵🔵 and the firmware update should be finished in a matter of seconds. Using DFU and performing a firmware update also helps recovering from most device-related issues.
-
-If LEDs 4 and 5 are flashing slow red 🔴🔴, it indicates an issue with DFU. Try to unplug and plug again or unplug and wait for it to timeout and try again the whole procedure.
-
-## The Application
-
-The application is the piece of software being loaded by the bootloader. It communicates with the client, emulates, reads and writes cards, drives the LEDs, handles buttons and much more. The application is also writable, it is the piece of software being updated via DFU.
-
-The communication with the application is either done via the CLI or a GUI. Communication can be done over USB or BLE (**B**luetooth **L**ow **E**nergy), although, at time of writing, only GUIs support BLE.
-
-On boot, the application starts in emulation mode, so it can emulate up to 8 HF tags and up to 8 LF tags (one slot can handle both a HF and a LF).
-
-The Chameleon can be awaken:
-
-- by pressing a button
-- when it comes close to a HF or LF field, *only if* a card corresponding to that field (HF/LF) is loaded into the active slot.
-
-The white LED labeled RF lights up when it detects a field, again only if the active slot supports it.
-
-In some situations, it can be cumbersome to wait for the boot-up animation. This is configurable, cf e.g. the CLI command `hw settings animation -h`.
-
-On a new Chameleon (or after a factory reset), 3 slots are defined, slot 1 holding both a HF and a LF:
-
-- slot 1 LF: a EM4100 with UID `DEADBEEF88`
-- slot 1 HF: a MIFARE Classic 1k with UID `DEADBEEF`
-- slot 2 HF: a MIFARE Classic 1k with UID `DEADBEEF`
-- slot 3 LF: a EM4100 with UID `DEADBEEF88`
-
-When a slot is selected, the LED shows what type of card is loaded with the following color code:
-
-- 🟢 HF card loaded
-- 🔵 LF card loaded
-- 🔴 Both HF and LF loaded
-
-When a dual HF/LF slot is activated by an external field, it will turn green or blue according to the frequency.
-
-The application controls the buttons. The behavior of the buttons is customizable via the CLI or a GUI. The default behavior is the following:
-
-- 🅐 short press: Select previous slot
-
-- 🅑 short press: Select next slot
-
-- 🅐 long press: Copy LF or HF tag UID (only Ultra, not Lite)
-
-- 🅑 long press: Copy LF or HF tag UID (only Ultra, not Lite)
-
-*About UID copy*: the action depends on the current slot support. So to be able to copy an EM4100 LF tag, the slot must be configured firstly to emulate an EM4100 tag. And to be able to copy a HF 14a tag, the slot must be configured for the right type of HF tag. Only the UID will be copied, not the data.
-
-The Chameleon also shows the following LED effects:
-
-- Charging: 4 pulsing green lights
-
-- CLI / GUI connected over USB: Chasing LEDs in the color of the selected slot (left to right for slots 1-4 and right to left for slots 5-8).
-
-The device enters sleep mode after about 5s unless it is plugged in USB or if a client is connected over BLE. You can use the buttons to wake it up again. You can also press quickly a button during the sleep animation to keep the device awake.
-
-## Write Modes
-- **Normal**: Behaves like any normal card
-- **Denied**: Read-only card, send NACK to write attempts
-- **Deceive**: Accepts write commands but don't change any data (reader thinks write was successful but when reading back, nothing changed)
-- **Shadow**: Accepts writes but reverts changes when device goes to sleep (reader can read and write like a normal card but changes are kept in RAM and are lost when the chameleon goes to sleep) 
-
-## The SoftDevice
-
-A [SoftDevice](https://infocenter.nordicsemi.com/index.jsp?topic=%2Fstruct_nrf52%2Fstruct%2Fnrf52_softdevices.html) is a precompiled and linked binary software implementing a wireless protocol developed by Nordic Semiconductor.
-
-We are using the [SoftDevice S140](https://infocenter.nordicsemi.com/index.jsp?topic=%2Fstruct_nrf52%2Fstruct%2Fnrf52_softdevices.html) which implements a BLE Central and Peripheral protocol stack solution.
-
-## The User Data
-
-The Chameleon has a reserved space of memory and flash where it stores application settings, active slot and slots configurations and data. This will not be overwritten by DFU updates and the data will only be reset by either issuing `hw factory_reset --force` in the CLI or clicking `Factory reset` in a GUI.
-*Warning:* Settings and/or data might be reset to defaults if you downgrade the firmware version up to a version not supporting the newer format.

-# Hardware
-
-The Chameleon comes in 3 Hardware variants, the Ultra, the Lite and the Devkit.
-
-## The Ultra
-
-The Chameleon Ultra comes in a black box with gold printing. This box has the following dimensions: 9.5 cm x 5.5 cm x 3.5 cm
-
-![box.png](./images/ultra-box.jpg)
-
-The Box contains a foam pad, a USB cable that has a removable end to convert it to USB-C, a Proxgrind 3.5 hex screwdriver, 2 replacement screws and a keychain and the device itself.
-
-![box-contents.jpg](./images/ultra-box-contents.jpg)
-
-The device itself features 4 screws holding it together, 2 buttons labeled `A` and `B`.  The device consists of 2 PCBs (**P**rinted **C**ircuit **B**oards) and a plastic spacer, one contains the Electronic and the HF (**H**igh **F**requency), 13.56 MHz, antenna as well as the 8 LEDs indicating which slot is currently active and the other board features the Chameleon Ultra text, the screws and the LF (**L**ow **F**requency), 125KHz, antenna. The plastic spacer houses the battery as well as the ferrite pad which enables HF and LF emulation at the same time. It also has has the USB-C charging and data port and a hole for inserting the keychain loop. The Chameleon Ultra dimensions are: 2.4cm x 4cm x 8mm 
-
-![ultra.png](./images/ultra.jpg)
-
-## The Lite
-
-The Chameleon Lite comes in a white box with blue printing. This box has the following dimensions: 9.5 cm x 6 cm x 3.5 cm
-
-![lite-box.jpg](./images/lite-box.jpg)
-
-The Box contains a foam pad, a USB cable that has a removable end to convert it to USB-C and the device itself.
-
-![lite-box.-contents.jpg](./images/lite-box-contents.jpg)
-
-The device itself features 2 buttons labeled with arrows. The device consists of one PCB in a blue plastic housing. This one PCB contains the electronics and the HF antenna as well as the 8 LEDs indicating which slot is currently active, and the USB-C port. The LF antenna is glued onto the back of the PCB and is visible through the housing. The battery is soldered in place and the housing is held together by thin fragile pins which are easy to snap. It is not designed to be disassembled. The keychain loop is also relatively fragile, so be careful. The Chameleon Lites dimensions are: 3.6 cm x 6.1 cm x 0.8 cm
-
-![lite.jpg](./images/lite.jpg)
-
-## The Devkit
-
-Just like the Chameleon Ultra, the Devkit comes in a black box with gold printing. This box has the following dimensions: 12 cm x  8 cm x 3.5 cm
-
-![devkit-box.jpg](./images/devkit-box.jpg)
-
-Again, just like the lite, the box contains a foam pad, a USB cable that has a removable end to convert it to USB-C and the device itself.
-
-![devkit-box-contents.jpg](./images/devkit-box-contents.jpg)
-
-The device itself features 2 buttons labeled `A` and `B`. The device is made of only one PCB without a case. At the bottom of this PCB both the HF and LF coils are found. Because it is a Devkit, this Chameleon has its SWD (**S**ingle **W**ire **D**ebug) port and some testpoints exposed. (In the photos below, a pinheader is already soldered into the SWD port, this is not the case from factory) The Chameleon Devkit dimensions are:  5.3 cm x 8.5 cm x 1.1 cm (including rubber feet, battery and buttons. PCB thickness: 0,16 cm)
-
-![devkit.jpg](./images/devkit.jpg)
-
-## What is the difference between the Lite and the Ultra/DevKit?
-
-The Chameleon Ultra as well as the Devkit contain a second chip called [MFRC522 ](https://www.nxp.com/docs/en/data-sheet/MFRC522.pdf). This chip allows the Chameleon to read and write to HF 14a tags. The Chameleon Lite does not contain this chip and therefore cannot read and write HF tags, it can only simulate some. The Chameleon Lite also swaps the big LIPO (**LI**thium **PO**lymer) battery with a smaller buttoncell. The Devkit is a Chameleon Ultra on a bigger PCB and with a bigger battery and some component differences such as a mechanical relay but which should not make any practical difference.
