As purchased from here.
Install the following Arduino libraries:
- In the Arduino sketches, ensure that the radio frequency you are using is commented/uncommented correctly
//#define LORA_BAND 433 //#define LORA_BAND 868 #define LORA_BAND 915
In the Arduino IDE, I chose the board 'TTGO LoRa32-OLED V1', compiled the sketch to verify it works, and then uploaded to the board. You'll need two boards, one to send, and one to receive. Ensure the LORA_BAND matches in both sketches otherwise they won't be able to communicate.
I designed a case based on the designs of similar cases on Thingiverse, which includes a spot for the antenna. It's a tight fit, but it should work fine.
