LoraButton cannot join, no logs only fail message


I’m using a LoRaButton RAK LB801 to connect to TTN through a Dragino gateway using LoRaWan protocol.
but when i tried to make an OTAA join it failed, it just say “Fail” when i execute the “at+join=otaa”

i already check the logs on the gateway and they are empty, but the configuration seems alright

here is an image with the configuration

so please any idea about why the gateway doesn’t receive the button signal even though it’s online is very much appreciated


here is the configuration i used on TTN

here is the config of the button







this issue is related with TTN and you could get more help from TTN forum. If any issue with cayenne, then let us know.


thanks, i will ask there
