+- **Q11: M5StickC Burning UIFlow Complete but screen has no display**
+
+
+
+
+ M5StickC does not automatically reset after the firmware is refreshed by default. You need to manually press the left power button.
+
+
+
+
+- **Q12: UIFlow display has been uploaded or downloaded successfully, the program changed**
+
+
+
+
+ The connection between the network and the server may be unstable. It is recommended to restart the M5Stack, refresh the hardware connection status and do it again.
+
+
+
+
+- **Q13: What is the difference between M5StickC and M5StickC+**
+
+
+
+
+ M5StickC and M5StickC+ are identical in hardware configuration, but M5StickC+ adds several HATs, which is more cost-effective than purchasing separately.
+
+
+
+- **Q14: M5StickV can not mount TF card**
+
+
+
+
+ First, make sure that the format of the TF card is FAT32 and no partition. Some large-capacity SD cards are usually formatted as NTFS, you need to confirm. The following tests are performed on the compatibility of the TF card.

+- **Q15: Send a zip to V-Training but the received e-mail does not contain a model file**
+
+
+
+
+ Carefully check the contents of the email. The training error will be indicated in the email. Only the specified two folders are allowed in the zip. The minimum number of photos and the classification are given. If there is a hidden file, the training will fail.

+- **Q16: The serial port is used in the Arduino program, but when running, it is found that the screen is not lit or constantly restarted**
+
+
+
+
+ M5.begin()At the time of initialization, the serial port baud rate is 115200 by default. Repeated definition will cause the program to be abnormal. If there is external serial port hardware, connect the hardware and then run.
+
+
+ First check your program carefully, confirm that there is no problem, then use M5Burner to erase, check whether it can be successfully cleared, and then burn FactoryTest.ino use arduino to check whether it can be burned. If it can be successfully operated, there is no problem. if MD5 file error occurs repeatedly, the probability that FLASH has been damaged.

+- **Q18: How to improve the battery of M5Stack and M5StickC**
+
+
+
+
+ First, optimize the program to reduce the number of unnecessary detections; secondly, by calling the sleep function, it is reasonable to sleep and wake up; in addition, the official battery base can be added.
+
+
+
+
+- **Q19: Is M5Stack Can connect 5G frequency band Wi-Fi**
+
+
+
+
+ ESP32 chip does not support WiFi in 5G band, only 2.4G can be connected.
+
+
+
+
+- **Q20: What is the difference between UIFlow's Micropython and the official Micropython**
+
+
+
+
+ UIFlow is based on the secondary package of the official Micropython, integrates a large number of M5 libraries, UIFlow is easier to understand and easy to use, and most of them are compatible with the official Micropython API.
+
+
+
+
+- **Q21: Some examples of Arduino are inconsistent with GitHub**
+
+
+
+
+ The examples in Arduino are used for the factory basic function test, the upgrade is slower, GitHub upgrade is faster, the code is more perfect, it is recommended to download directly from GitHub.
+
+
+
+
+- **Q22: Wether BASIC can use UIFlow and M5GO accessorie**
+
+
+
+
+ UIFlow is available, but some features are not available in the hardware part of UIFlow. M5GO accessories are compatible.
+
+
+
+
+- **Q23: Does it can display Chinese**
+
+
+
+
+ Support GB2312 code in Arduino , refer to hzk16 example . Micropython environment not supported yet, due to limited by execution speed and UTF-8 file size.
+
+
+
+
+- **Q24: M5Stack BASIC has been in normal use and suddenly cannot be turned on even if USB is connected**
+
+
+
+
+ Remove the BASIC base and try again. It is most likely caused by poor contact between the base and the M-BUS.
+
+
+
+
+- **Q25: About M5StickV tutorials**
+
+
+
+
+ M5StickV uses K210 chip compatible with Maixpy development environment, you can refer to Maixpy's official documentation.
+
+
+
+
+- **Q26: Some APIs are not found in the docs**
+
+
+
+
+ The reference API provided is the functions of the M5 hardware package. The application libraries such as WIFI, HTTP, etc.There are not included in the scope of provision. For reference, other ESP32 and Arduino libraries are used.
+
+
+
+
+
+- **Q27: The button is used in the Arduino program, but it will not work after pressing it once**
+
+
+
+
+ Using buttons and speakers requires adding M5.update() after execution to respond.
+
+
+
+
+- **Q28: I want to use the official sensor accessories, but also want to connect my own sensor, how to stack**
+
+
+
+
+ It is recommended to use the base of PLUS module + CORE.
+
+
+
+
+- **Q29: After M5Camera writing the program, it was found that the screen was reversed**
