Fork of mDot_LoRa_PEER_TO_PEER by
This example will setup a peer to peer node, copy program to two dots Uplink packets will be sent every 5 seconds, however communication is half-duplex An mDot cannot receive while transmitting
This example also demonstrates asynchronous receive through libmDot using the event framework.
Received packets will be sent to the Serial port on pins 2 and 3 baud rate for serial ports is set to 115200
