5.3 Broadcasting address

For example: Set the address of module A as 0xFFFF or 0x0000, and the channel as 0x04;

When module is the transmitter (transparent transmission), all modules under channel 0x04 will receive the

data, the purpose of broadcast is realized.

5.4 Monitor address

For example: Set the address of module A as 0xFFFF or 0x0000, 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, 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 per 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 send & receive 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
