Currently im having issues with joining the TTN Network. My gateway is showing the device (SX1276 with DIO0/DIO1/DIO3/DIO03 connected to nucleo-l452re). TTN accepts the join and sends out the acceptance message but the node is refusing it or it looks like the join acceptance is to slow. (RX Window closed before it was getting the join acceptance) Im using this example: https://github.com/RIOT-OS/RIOT/tree/master/examples/lorawan with OTAA joining

What might be the problem? AppKey / App EUI / Dev EUI should be good…
