Installation

Using the Betaflight App​

This is a generic procedure to flash a board using the app.

Make sure you have the Betaflight App either installed or opened in a browser, then:

  • Connect the flight controller to the PC.
  • Open the betaflight App.
  • Click on "Disconnect" if the app connected to the board automatically.
  • Click on the "Firmware Flasher" tab.
  • Make sure you have internet connectivity.
  • Click on the "Choose a Firmware / Board" dropdown menu, and select the latest stable version for your flight controller.
  • Select the build options relevant to you (e.g. make sure you choose an OSD protocol - you will be asked!).
  • Click on the "Load Firmware [Online]" button (the firmware will build)
  • IMPORTANT: Read and understand the release notes that are displayed. When upgrading review all release notes since your current firmware.
  • If this is the first time Betaflight is flashed to the board, tick the "Full Chip Erase" checkbox.
  • Connect the flight controller board to the PC. Ensure the correct serial port is selected.
  • Click on the "Flash Firmware" button and hold still (do not breathe, too).
  • When the progress bar becomes green and reads "Programming: SUCCESSFUL" you are done!

Manually​

See the board specific flashing instructions.

Upgrading

When upgrading be sure to backup / dump your existing settings. Some firmware releases are not backwards compatible and default settings are restored when the FC detects an out of date configuration.

Backup/Restore process​

See the CLI section of the docs for details on how to backup and restore your configuration via the CLI.
