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
5.6.2 Indication of wireless transmitting
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
