How to debug MKRWAN connection issues?

Hi,

Im trying to connect the MKRWAN 1310 board to the TTN. I see activation calls in the TTN console but do not get a connection. There are many gateways round, so there should be enough coverage. Any idea how to debug this? Can I turn on more debug information and might see what the response from the gateway is?

Thanks for any help on this!

I found a solution to the problem above myself by adding a long delay between modem.begin and modem.joinOTAA of 10 seconds. I don't know why this is necessary but in my case it helps.
