» LoRaWAN P2P 01: Configure

This example shows how to configure the module for P2P mode and the corresponding parameters. The user must keep in mind that every time the module is switched on, the radio settings MUST be set again.

Required Materials

1 x Waspmote
1 x Battery
1 x LoRaWAN module
1 x 868 MHz antenna
