## Example

### 1. Arduino IDE

These are the point-to-point communication [examples](https://github.com/m5stack/M5Stack/tree/master/examples/Modules/LORA868_SX1276/LoRa868Duplex) between two LORA868 modules. The LoRa nodes send and receive messages.

* Blue string indicates sending succeed.

* Yellow string display the received messages.

* Red string indicates initialization failed.
