TTOG still not listed as online

This has been going on for a minute but I’m just getting around to dealing with it. The TTOG seems to be properly configured, but it’s not showing up in my dashboard as on-line:

And it looks to be configured correctly:

but my console still shows:

Any ideas??

There is an issue with the console being rather unreliable:

Use a device to uplink, check your gateway logs, look at the gateway console traffic, look at the device uplinks.

I have done this. Previously I had 2 gateways, so I powered the other one down (it was working fine, but was indoor-only) and once that one is powered off, I get no connections.

I’m basically trying to run a “Hello World” on an RPiZero. It was able to connect when the indoor gateway is on, but with that powered off, I get:

File "/usr/local/lib/python3.7/dist-packages/rak811/rak811.py", line 401, in join_otaa
raise Rak811EventError(status)
rak811.rak811.Rak811EventError: [Errno 6] Rx2 timeout

There is zero traffic in the gateway logs indicating even an attempt to connect by the client.

I guess this could be part of the problem :slight_smile:

whereas:

The TTN back end NS’s are behind load balancers (AWS) so ping doesnt work, am afraid those results dont help you!

If the gateway logs do not list any valid LoRaWAN packets being received you should:

  1. Check the frequency plan. Is your gateway listening at the frequencies your node transmits?
  2. Check antenna connectors and cable and make sure you connected to right antenna to the right connector. TTOG has multiple connectors and you need to use the right one for the LoRaWAN antenna.
  3. Make sure to have the node antenna at least 12 feet away from the gateway antenna. Larger distance is better.
