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, perform hardware self-check, and set the working

mode according to user parameters. During this process, AUX keeps low level, and after completion, AUX outputs high level,
and starts to work normally according to the working mode formed by the combination of M2, 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 AUX detailed

It indicates whether the module has data that has not been transmitted wirelessly, or whether it has received wireless data that has

not been sent out through the serial port, or whether the module is in the process of initializing and self-checking.

5.6.1 Serial data output indication

Used to wake up the external MCU in sleep (note that there is no delay in AUX indication in continuous transmission mode)


5.6.2 Wireless transmission instructions

In sub-packet transmission mode, the internal buffer size is specified by the sub-packet size. For example, if the packet length is

set to 221 bytes, the corresponding buffer size is 2048 bytes. When AUX=1, the user can continuously initiate data that does not
exceed 2048 bytes.
In the continuous transmission mode, when AUX=1, it means that the current module is busy, but it is not suitable for waking up

the external MCU because the data is sent faster during continuous transmission.
When AUX=1, it means that all serial port data of the module has been transmitted wirelessly, and the module is in an idle state.
