CubeCell + TTN + US915

Hi!

I am trying to connect a CubeCell board to a LoRa Gateway that is connected to The Things Network (TTN) with the LoRaWan example provided by Heltec (from the example, I just changed the devEUI, appEUI and appKey, everything else is the same). I’ve been struggling with this, I can’t make my CubeCell board connect to TTN. I have double checked the frequency plan and the keys.

In my gateway I can see this:

But in Arduino Serial Console I just keep receiving “join failed, join again at 30s later

Any ideas? Thanks for your help.

“ join failed, join again at 30s later ”, means: attempt join twice failed then serial print this this sentence.

Is your frequency US915MHz?(US915 and AU915 are not same frequency) What’s your gateway?(heltec made?)

I have a RAK831 Gateway. It works fine with other Heltec boards like the WiFi LoRa 32. My frequency is US915MHz.

I’ve also tried using the US915 (hibrid) from the board configuration, still no success.
