Hi Dave,

Please check the AVR boards manager version you are using to compile the code. As stated on the download page, for the Pro2 PLUS it shouldn't be greater than 1.6.21.

IMPORTANT:
Always compile using the provided libraries.
Tested with Arduino IDE 1.8.13 using AVR Boards Manager 1.6.21.
Not work reliably with AVR Boards Manager equal or greater than 1.6.22

Additionally there are on the forum some topics about this matter.


King regards

Hi Werk_AG

That will be the problem I think. I have been playing with LoRa shields for Arduino lately and updated the AVR Boards Manager.

Thanks

Dave
