6.1 Mode Switch
The user can decide the operating mode by the combination of M0, M1 and M2. The two GPIOs of MCU can be
used to switch mode. After modifying M0, M1 or M2, it will start to work in new mode 1ms later if the module is
free. If there are any serial data that are yet to finish wireless transmitting, it will start to work in new mode after the
UART transmitting finished. After the module receives the wireless data & transmits the data through serial port, it
will start to work in new mode after the transmitting finished. Therefore, the mode-switch is only valid when AUX
outputs 1, otherwise it will delay.
For example, in mode 2 or mode 4, if the user inputs massive data consecutively and switches operating mode at the
same time, the mode-switch operation is invalid. New mode checking can only be started after all the user's data
process completed. It is recommended to check AUX pin out status and wait 2ms after AUX outputs high level before
switching the mode.
If the module switches from other modes to stand-by mode, it will work in stand-by mode only after all the remained
data process completed. The feature can be used to save power consumption. For example, when the transmitter
works in mode 0, after the external MCU transmits data "12345", it can switch to sleep mode immediately without
