It was working fine in my last gateway whith :

  • loraserver 2.0.0
  • lora-app-server 2.0.0

And now i’m using version 2.7.0.

In the log of the loraserver it’s clearly writteen : device-activation created

Thanks

  • Check the gateway logs to see if it is actually transmitting

  • Add logging to the node to see if it is attempting to receive, if it is finding anything, possibly rejecting the packet, etc

Hi,

I fixe the problem !
I the loraproject 2.0, we had just to specifie if the version of the node is 1.0 or 1.1 , But now with the version 2.7 we must specifie the exact version, and this is what i do 1.0.0, now it’s work fine !
