Finally the error were in the python side....I have had modified the python test code in order to check what was happening and I have changed something...(dammit!) I have tried with the simple ABP example from Pycom and it works. Then I tried with your original example an it is working (uplink and downlink):

Device was joined (again)
Message:

I will do more testing, thank you for the support and for the patience!

That's excellent, and thank you for testing and the PR.

I changed the name of the board from "HELTEC" to "TTGO". So you can use:

make BOARD=TTGO FLASH_SIZE=4MB ....
