LoRa Serial Passthrough
For many network you will need the hardware eui to register your device on their network.
Replace [x] with your own keys.
| Command | Action |
| sys reset | Will reset the module and shows the version on the module |
| sys get ver | Firmware version of the RN2XX3 module |
| sys get hweui | Get the hardware eui |
| mac set devaddr [x] | Set the device address |
| mac set nwkskey [x] | Set the network session key |
| mac set appskey [x] | Set the application session key |
| mac join abp | Join the network with personalized keys |
| mac tx uncnf 1 01 | Send the hexadeciamal message “01” unconfirmed on port 1 |
