This module is under active development. You can test it at you own risk ! ;).Node-RED modules to address the LoRaWAN RN2483 and RN2903 radio modules.
RN2483 and RN2903 are module produced by Microchip. You can read the "RN2483 Command Reference User's Guide" and the "RN2903 Command Reference Users Guide" to understand the protocol used over the serial connexion.
The node currently only address the LoRaWAN P2P protocol with hard coded values. But next release should enable the possible to configure the setup process of the chip.
The code has been tested with the "Raspberry Pi to Arduino Shield Connection Bridge" and a LoRaWAN RN2483 radio module
You can have a look to the ArduPi github repository to have usage samples without Node-RED.
