If the module firmware is developed using the MXOS development platform provided by MXCHIP, the
application will also check the status of the following pins during the boot process to enter a special
working mode. These features can be adjusted by modifying the code. The default features are described
below. Before the final production, if these functions are useful, a verification test is required.
There are currently three working modes to choose from:
Normal: The application runs normally.
ATE: Runs the RF test mode, in which the RF transmit power, receive sensitivity, and RF parameters
can be tested. Interact with the ATE command using UART_LOG (TX: PA7, RX: PA8).
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, login information of the cloud service and basic hardware. Features.
When detecting the pin state, the firmware first sets the mode of PB1 and PB23 to the input pull-up.
Therefore, if the external does not interfere, the IO state is high, and the default working state is: Normal.
