RadioLib LoRaWAN Starter Example
|
|
|
|
! Please refer to the included notes to get started !
|
|
|
|
This example joins a LoRaWAN network and will send
|
|
uplink packets. Before you start, you will have to
|
|
register your device at https://www.thethingsnetwork.org/
|
|
After your device is registered, you can run this example.
|
|
The device will join the network and start uploading data.
|
|
|
|
Running this examples REQUIRES you to check "Resets DevNonces"
|
|
on your LoRaWAN dashboard. Refer to the network's
|
|
documentation on how to do this.
|
|
|
|
For default module settings, see the wiki page

|
|
|
|
