Initial button press wakeup of 4 seconds is sometimes inadequate to establish BT connection.
This change will expand the Initial button wakeup from 4 seconds to 8 seconds.
Device sleep behavior after will be as follows:
(Changed)
Initial Button Wakeup to Sleep : 8s
(No Change)
Subsequent Button Action to Sleep : 4s
Leaving RF Field wake to sleep : 3s
BLE Disconnect to sleep : 4s
USB Power Disconnect to sleep : 3s
Example behavior :
User wakes device with Button B (8 Sec to sleep)
User pushes button B again (Now 4 Sec to sleep)
User Places device in RF field (Maintain wake)
User removes device from RF field (3 sec to sleep)
If user discontinues the user journey at any point, the identified condition will invoke sleep at defined times.
nfc_tag_mf1_write_mode_t has one new mode SHADOW_REQ.
Client can set SHADOW or SHADOW_REQ, internally it will be transformed to SHADOW_REQ.
When it's time to save data, if SHADOW_REQ, the fw will change it to SHADOW and still allow to save the data before acting as shadow.
Breaking: when client reads back MF1 write mode just after settings SHADOW and before saving config, it will receive SHADOW_REQ and must be ready to handle this new enum value.
Now data length is always in bits
Option -o => -a and only needed to turn field on without select or data
Reorganize pcd_14a_reader_raw_cmd
Some more checks
Disruptive changes:
- tag types are 2-byte long with new values
- GET_SLOT_INFO returns 32 bytes as tag types are now 2-byte long
- "enable" is not common to one slot anymore but bound to the HF or LF part
- GET_ENABLED_SLOTS returns 16 bytes as we get "enabled_hf" and "enabled_lf" for each slot
- SET_SLOT_ENABLE needs 3 bytes slot_number|sense_type|enable as we need to specify to enable HF or LF
- slotConfig changed a lot but this is internal to the fw and its flash and a function does the format conversion on first boot after flash
so slot data is preserved on fw upgrade, but if one downgrades to a previous version, data will be erased.
MF1_DETECT_DARKSIDE was actually runnign the full attack, as there is no quick way to detect Darkside
So if you want to check for Darkside, just run directly MF1_DARKSIDE_ACQUIRE.
