+This example shows how to connect two Pycom LoRa capable modules (nodes) via raw LoRa. **Node A** will continuously send a packet containing `Ping`. Once **Node B** receives such a packet, it will respond with `Pong`. You will see the count messages appear in the REPL. You can adapt this example to have mutual communication between two LoRa nodes.
