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.

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.

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.

To wake up external MCU



Buffer (empty): the internal 256 bytes data in the buffer are written to the RFIC (Auto sub-packaging). When AUX=1, the user

can input data less than 256 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 256 bytes data in the

buffer have not been written to the RFIC completely. If the user starts to transmit data at this circumstance, it may cause overtime

when the module is waiting for the user data, or transmitting wireless sub package. When AUX = 1, it does not mean that all the UART
