LoRaWAN Global 04: Join ABP send unconfirmed

This example shows how to configure the module and send packets to a LoRaWAN gateway without ACK after join a network using ABP.

Required Materials

1 x Waspmote 1 x Battery 1 x LoRaWAN Global 1 x 868 MHz Antenna (for EU and IN bands) or 900 MHz Antenna (for AS, US, AU and KR bands)

Notes

- The battery has to be connected. - This example can be executed in Waspmote v15
