Special Function Capture Pin
The module will detect the status of these pins during power-on to enter some special modes and functions.
These functions are determined by the hardware and cannot be modified.

If the module firmware is developed using the MXOS development platform provided by MXCHIP, the
application will also detect the status of the following pins during the boot process and enter a special working
mode. These functions can be adjusted by modifying the code. The default functions are described below.
Before final production, if these functions are useful, verification testing is required.
There are currently three working modes to choose from:
▪ Normal: Run the application normally.
▪ ATE: Runs the RF test mode. In this mode, you can test the RF transmit power and receive sensitivity and
calibrate the RF parameters. Use UART_LOG (TX: PA7, RX: PA8) to interact with the ATE command.
▪ QC: Run the factory test mode, output QC information through LP_UART (TX: PB1, RX: PB2), and cooperate
with the detection program running on the PC, which can be used to verify the firmware version in the
module, the login information of the cloud service, and basic hardware Features.
When detecting the state of the pin, the firmware first sets the mode of PB1 and PB23 to input pull-up.
Therefore, if there is no external interference, the read IO state is high, and the default working state is: Normal.
