Dont fret if you're not in the US - you'll just have to make some small modifications to your code to ensure it runs on the correct region. The Arduino-Lmic library supports the following regions:
- eu_868: EU
- us_915: US
- au_921: Australia
- as_923: Asia
- in_866: India
First, within the directory of your sketch, create a new folder named project_config.
Open the Arduino IDE and copy and paste the contents of the lmic_project_config.h file into the IDE:
Simply uncomment the region your device is located in. We use a SX1276 transceiver on the Feather M0 LoRA, so this definition should not be changed.
