Hello,
I’m using gateway with balena.io and https://github.com/jpmeijers/ttn-resin-gateway-rpi.
In case I connect the gateway using ethernet, everything is fine.
But if I use cellular modem, start fails with “Unable to fetch configuration from TTN. Are your GW_ID and GW_KEY correct?”
I can ping google from the container or curl https://account.thethingsnetwork.org/api/v2/frequency-plans/, so the cellular connection seems to be ok.
My guess: When I run from cellular, the cellular connection is not yet ready when the container is started so the connection attemp and the retry within 30sec by the application fails.
Is there a chance to wait with the container start until cellular is connected?
If I restart the container some minutes Raspberry runnung, the application container works fine.
I’m using Huawei MS2131 cellular adapter.
thanks and regards,
Thomas
