SX1280 Wireless Module

5.3. Broadcast Address

i.e.: set the address of module A as 0xFFFF or 0x0000 and channel as 0x04.

When set A as transmitter (same mode, transparent transmission on), all modules with channel 0x04 will receive broadcast

data.

5.4. Monitor Address

i.,e.: set the address of module A as 0xFFFF or 0x0000 and channel as 0x04.

When set A as receiver, it will receive the data transmitted by modules with channel 0x04.


5.5. Module Reset

When the module is powered on, the AUX output will go to a low level immediately, the module conducts hardware

self-check and sets the operating mode on the basis of the user parameters (M0 M1). During the process, the AUX level
remains low. After the process completed, the AUX outputs high a level and starts to work as per the operating mode
indicated by the combined state of M1 and M0. The user needs to wait until the AUX rising edge is high, indicating the
module is ready for 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 is data

that is yet to send via wireless 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 serial output

Used to wake up the external MCU (note: AUX indicates no delay under continuous mode)


5.6.2 Indication of wireless transmission

Under sub-packet transmission mode, the internal buffer size is determined by the sub-packet size, if the packet length is 221

bytes, then the buffer size will be 2048 bytes, when AUX=1, user could continuously initiate transmitting of no more than
2048 bytes.
Under continuous transmission mode, AUX=1 means the module is busy, but it is not applicable for waking up external

MCU, because the data transmission is very quick under continuous transmission mode.
AUX=1 means all serial data is transmitted through RF, and the module is at idle state.


5.6.3 Module in configuration process

Only occurs when resetting or when exiting sleep mode
