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.
5.6.1 Indication of UART Output
®
To wake up external MCU
All the wireless data received have been
To wake up the external
sent by TXD.(The buffer is actually empty.)
MCU
2-3ms in advance
