purpose of broadcast is realized.
5.4 Monitor address
 For example: Set the address of module A as 0xFFFF, and the channel as 0x04;
 When module A is the receiver, it can receive the data sent from all modules under channel 0x04, the purpose of
monitor is realized.
5.5 Reset
 When the module is powered on, AUX outputs low level immediately, conducts hardware self-check and sets the
operating mode based on user’s parameters. During the process, the AUX remains low level. After the process
completed, the AUX outputs high level and starts to work as the operating mode combined by M1 and M0.
Therefore, users need to wait the AUX rising edge as the start of module’s normal work.
5.6 AUX description
 AUX Pin can be used as indication for wireless sending & receiving buffer and self-check.
 It can indicate whether there are data that are not sent yet via wireless way, or whether all wireless data has been
sent through UART, or whether the module is still in the process of self-check initialization.
5.6.1 Indication of UART output
 To wake up external MCU
