5.3 Broadcasting Address
® Example: Set the address of module A to OXFFFF and the channel to 0x04.
® When module A is used as a transmitter (same mode, transparent transmission mode), all receiving modules under the 0x04
channel can receive data to achieve the purpose of broadcasting.
5.4 Monitor Address
® For example: Set the address of module A as OxFFFF 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
® After the module 1s 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 AUX outputs high level after completion,
and starts to work normally according to the working mode formed by M1 and MO; Therefore, the user needs to wait for the
rising edge of AUX as the starting point for the module to work normally.
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.

5.6.2 Indication of Wireless Transmitting
® Buffer empty: the data in the internal 400-byte buffer is written to the wireless chip (automatic sub-packaging),
When AUX=1, the user continuously initiates data less than 400 bytes without overflow,
When AUX=0, the buffer is not empty: the data in the internal 400-byte buffer has not been written to the wireless chip and the
transmission is turned on. At this time, the module may be waiting for the end of the user data to time out, or the wireless
sub-packet transmission is in progress;
[Note]: When AUX=1, it does not mean that all serial port data of the module has been transmitted wirelessly, and the last packet
of data may be being transmitted.
Subpackage transmitting : the last package of data have been
written to the RFIC. When transmission is on, user can continue
to input 400 new bytes. (The buffer is actually empty.)
