we bought the new MKR WAN 1310 and we do run in multiple issues by uploading any sketch and libaries to the board.
It doesn't work at all if you select MKR WAN 1310 board in the IDE. The only message you get ist "Starting Lora failed" - no matter what you do.
If we select the older MKR WAN 1300 board in the IDE we are able to start the Lora sender at least but still not able to change anything or get the lora receiver working. We don't get any response from the device, it is like you haven`t successfully uploaded the sketch, since not even the first line with "Lora Receiver" comes up.
Someone else seems to have the same issue with the new board:
Can someone please help?
