Transplanted from Semtech LoRaWAN(https://github.com/Lora-net/LoRaMac-node) protocol to "ESP32 + Arduino" platform. Use RTC, support deep sleep, only working with ESP32 + LoRa boards made by HelTec Automation(TM). Need a unique license to use it.
Why do you think that https://github.com/JustDr00py/heltec-LoRa32-Micropython is a good alternative to ESP32_LoRaWAN
