How to flash

  1. Plug the device into your computer with a USB-C data cable.
  2. Click Connect next to your device and pick its serial port.
  3. Click Install, leave Erase device unchecked, then Next and Install. Erasing wipes your saved settings and the Heltec LoRa license.
  4. If it won't connect, hold the PRG/BOOT button while plugging in, then try again.

Already running SuperLiveTimer? You can also update over WiFi from the device's config page using the -ota.bin file.

Restore Heltec LoRa license

Lost license?

Heltec boards only. If a board was erased and its radio stopped working, this reads its chip ID, looks the license up on heltec.cn and writes it back.
