This looks like a coding/hardware issue and not LoraWAN per se so you’ll have trouble getting help here. Perhaps you should look at a Heltec forum for assistance.

I have not used the Heltec version of the code but I have successfully built a test node on a Heltec V1 using the Arduino LMIC code. You may like to try that.
