I have some node rak3172 inside, and now I want to develop some boards using another Rak module. So wonder if Rak3172 can communicate with another type Rak module?
Welcome to the forum @Nam
Any module with LoRa transceiver can communicate to another LoRa module (not only RAK ones) using the LoRa P2P transmission.
You have to set both modules into LoRa P2P mode, set the same SF, BW, CR, Preamble Length and frequency on both modules. then you can send data from one LoRa node to another one.
For the RAK3172 the AT commands can be found in our Documentation Center
For example you can use these commands:
Command | Explanation |
---|---|
AT+NWM=0 | sets LoRa P2P mode, node will restart after that command |
AT+P2P=868000000:7:0:0:20:14 | sets the frequency and other parameters AT+P2P |
AT+PRECV=65534 | Listen to incoming LoRa P2P packets AT+PRECV |
Then you have to setup the other node the same way and start sending data:
Command | Explanation |
---|---|
AT+NWM=0 | sets LoRa P2P mode, node will restart after that command |
AT+P2P=868000000:7:0:0:20:14 | sets the frequency and other parameters AT+P2P |
AT+PRECV=0 | Stops RX mode |
AT+PSEND=30313233 | Sends a packet with the payload 0x30 0x31 0x32 0x33 |
