I am pretty new over here. I did buy a used iC880A with a Pi 3 with it. The board has been working on the TTN network so there is something going on in my config.
I did follow up the https://github.com/ttn-zh/ic880a-gateway to setup the device and everything seems to be working fine.
After a while i did notice that my gateway isn’t registering at the TTN.
Unfortunately the service will not start because there is something wrong with the JSON file. Anybody have a golden hint?
