Im trying to connect my Arduino MrkWan 1310 to the TTN. I can see activation calls in the TTN console with different gateways but I do not get a connection and therefore no data can be sent. Any Idea how to debug this? Im using the latest version of the mrkwan library: https://github.com/arduino-libraries/MKRWAN/blob/1.0.11/src/MKRWAN.h
Thanks for any hints!
