Hello,
I was making some changes to the code on my TTN Uno but it no longer seems to want to join my network.
I previously configured it to join the network and everything was working fine.
I cant quite work out why its not sending the data like before - everything seems to be the way it should be.
I am getting the following serial log
Sending: mac join otaa
Join accepted. Status: 00000401
DevAddr: 260B54D4
Sending: mac set class a
Response is not OK: invalid_param
