FlySight 2 firmware (fork)

A custom firmware and new audio files for FlySight 2. Version v2026.09.09.develop-23-g07926e1.

Firmware

  1. Connect the FlySight to your computer with USB.
  2. Push and hold the button until the FlySight resets and the light turns orange (about 10 seconds).
  3. Upload the FLYSIGHT.TXT file from the FlySight. The website returns APP.SFB for the hardware batch of your FlySight.
  4. If necessary, make a folder with the name FW on the FlySight.
  5. Copy APP.SFB into the FW folder.
  6. Eject the FlySight.
  7. Disconnect the FlySight from the computer. Wait a few seconds while the FlySight resets and installs the firmware.

The server reads only the Pubkey_X line, to find the hardware batch. It does not keep the file. With the FlySight app, you can also install APP.SFB over Bluetooth (Device > Firmware).

Audio files

This firmware speaks words that the original audio files do not have, for example “H speed”. Install these audio files with the firmware.

  1. Download the ZIP file and extract it. It has one folder, AUDIO, with 62 sound files.
  2. Copy the AUDIO folder onto the FlySight. Replace the old files.
