Solve problem with LMIC joining to TTN

Primary tabs

I did struggle a bit with getting a stm32 Nucleo-L476RG and a RFM95 to join the TTN.

I did change to DF10 when joining ...se below picture ...

And then i did change back again to DF7 when it has joined ..see below picture

And it was very fast to get joined and send the first packet ....
