You are correct - it seems that TTN has more users.
I was hoping that someone would be able to assist since this is a Adafruit 32u4 Lora board using the LMIC libraries.
The questions still remain
- If a downlink payload is encrypted, is it possible using the LIMC library to decrypt it?
- In the TTN network are all downlink messages encrypted by default since this seems to be the standard.
