Remarks
1
The user can decide the operating mode by the combination of M1 and M0. The two GPIO of MCU can be used to
switch mode. After modifying M1 or M0, it will start to work in new mode 1 ms 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.
2
For example, in mode 0 or mode 1, 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 pinout status and wait 2ms after AUX outputs high level before switching
the mode.
3
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 waiting the
rising edge of the AUX pin, also the user’s main MCU will go dormancy immediately. Then the module will transmit all
1
Due to the characteristics of TDD and frequency modulation spread spectrum, the module can operate at the same time.
2
Lock is used to indicate the synchronization situation for both side (transmitter and receiver). When lock is high level,
synchronization completed, communication is available. Otherwise when lock is low level, synchronization completed,
communication is unavailable (data lost).
