after The Things Conference I did set up The Things Uno and it was able to join TTN via my picoGateway (8 chan) at home and also with the gateways in the city of Aachen.
Then 2 days ago the Uno stopped working and now rejects to join the network. I did check coverage and my gateway at home. I also checked the status page of TTN. All systems are working just fine.
After digging around a bit, I updated the RN2483 from 1.0.1 to 1.0.3 to check if it was a chip related issue. Sadly this didn’t work out, too.
Microchip LoRa dev util shows:
21:33:56.652 > mac join otaa
ok
denied
The TTN console for the gateway just keeps blank all the time. No join request is registered.
The TTN console now shows the join request, but the join is not successful as before…
Is there anything else I could check?
Could this be a hardware related issue, like the antenna is broken or smth. like that?
Could be related to the outage of the EU bridge, but the node went offline at about

Perhaps the UDP flood began on Monday and the collapse of the TTN backend was just today.
I will give it a try tomorrow, when TTN is back to normal…
…but it should also show a Join Accept response if the keys were accepted and the same gateway was selected to transmit that (or some error if all gateway(s) are busy). And the device’s Data page should show the activation too, if the keys were accepted.
the TTN Uno is just configured normal. I also did a full reset and reconfigured it, but the result is just the same. The Uno is powered by a 5-Port USB-Power-supply rated 40W total with 2.4A max per Port. And only 3 devices connected one mobile phone, a twine temp sensor and the TTN Uno…

Ok, after removing the device from my app, and re-adding it, with the new AppKey, everything works fine. Don’t really know, what made the UNO run mad, but now it looks quite normal.
