5.3 Broadcast address

Example: Set the address of module A to 0xFFFF , and the channel to 0x04 .

When module A is used as a transmitter (same mode, transparent transmission mode), all receiving modules under
the 0x04 channel can receive data to achieve the purpose of broadcasting.
5.4 Listening address

Example: Set the address of module A to 0xFFFF , and the channel to 0x04 .

When module A is used as a receiver, it can receive all the data under the 0x04 channel to achieve the purpose of
monitoring.
5.5 Module reset

After the module is powered on, AUX will immediately output low level, and perform hardware self-test, and set
the working mode according to user parameters; During this process, AUX keeps low level, and after the
completion, AUX outputs high level, and starts to work normally according to the working mode composed of M1
and M0 ; Therefore, the user needs to wait for the rising edge of AUX as the starting point for the normal operation
of the module.
5.6 Detailed explanation of AUX

AUX is used for wireless transceiver buffer indication and self-inspection indication.

It indicates whether the module has data that has not been transmitted through the wireless, or whether the received
wireless data has not been sent through the serial port, or the module is in the process of initializing self-test.
5.6.1 Serial port data output indication

Used to wake up the external MCU in sleep ;
