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 MO.
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.

Buffer (empty): the internal 512 bytes data in the buffer are written to the RFIC (Auto sub-packaging).
®
When AUX=1, the user can input data less than 512 bytes continuously without overflow. Buffer (not empty): when
AUX=0, the internal 512 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

When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps the
