LoRa-MAC (Raw LoRa)

Basic LoRa connection example, sending and receiving data. In LoRa-MAC mode the LoRaWAN layer is bypassed and the radio is used directly. The data sent is not formatted or encrypted in any way, and no addressing information is added to the frame.

For the example below, you will need two F1 starter kits. Run the code below on the two F1 starter kits, you will see the word ‘Hello from LoRa chat’ being received on both sides.
