RNodeTHV4 Flash Utility
Flash the RNodeTHV4 boundary node firmware to a Heltec WiFi LoRa 32 V4.
No PlatformIO required — just Python 3 and a USB cable.
Usage:
# Flash a pre-built merged binary (from GitHub Releases or local build)
python flash.py
# Flash a specific file
python flash.py --file rnodethv4_firmware.bin
# Download latest from GitHub and flash
python flash.py --download
# Specify serial port manually
python flash.py --port /dev/ttyACM0
# Just build the merged binary (requires PlatformIO build output)
python flash.py --merge-only
