5. Function Detailed Explanation

After the module is powered on, AUX will immediately output a low level, perform hardware self-test, and set the working mode

according to user parameters. During this process, AUX remains low level. After completion, AUX outputs high level and starts

working normally according to the working mode combined by M1 and M0. Therefore, the user needs to wait for the rising edge of

AUX as the starting point for the module to work normally.

AUX is used for wireless transceiver buffer instructions and self-test instructions.

It indicates whether the module has data that has not been sent out through the wireless, or whether all the wireless data has been

received but has not been sent out through the serial port, or the module is in the process of initializing self-test.

Note: The picture below only illustrates the AUX function. The time and other specific data involved in the picture do not

represent the actual parameters of the module. Please refer to the actual test for specific parameters.

After the module receives valid wireless data, it will immediately pull AUX low and start the serial port to output data. After the

data output is completed, it will pull AUX high again.
