i recently started with lorawan/ttn and successfully registered my own gateway (dragino lps8).
Ttn says it is ‘connected’.
Now i’m trying to set up my first temperature/humidity Sensor (tabs tbhh100).
These sensors are pre-configured, so when i bought it, i got dev eui, app eui and an app key.
Both gateway and sensor are using the eu-868 frequency range.
Next step was to create an app in ttn console and to register this sensor with those given values.
The app contains both the ttn generated app eui and the given app eui.
Now this sensor sends join requests which i can see in my gateways traffic overview (using different frequencies, backoff strategy etc).
The request contain the dev eui, app eui and app key (and the values are correct, just like the ones i used to register that sensor device - i already checked that multiple times…)
And the request has an encoded payload field, which contains a dev nonce value, which gets incremented with every join message.
So from my point of view everything seems to be correct.
If i understand that right, ttn would have to send a join response, but i can’t see anything like that - neither in gateway traffic list nor in the data overview of the device itself
And aside from that there’s no error message at all (at least i can’t find anything like that)
What can i do to debug this situation? How can i find out what’s going on , if ther’s any error with ids/eui, payload etc? What settings should i check?
I kindly appreciate any help!
