We recommend using the online FLARM Configuration Tool to generate a configuration file. The tool requires you to select the correct device first. If you have an account and are logged in, you can select previously configured devices.
Click "Start Configuration" to show the configuration form for the selected device. When all items have been configured accordingly, click the "Create Config File" button to download the configuration file.
The file must then be copied to an SD card or USB stick, as applicable for the device being configured, formatted with FAT32. Insert the card or USB stick into the device and turn it on. The configuration will be applied automatically during boot. The SD card or USB stick may not be left in the device during flight.
For details, refer to the manual of the respective device: https://flarm.com/support/manuals-documents/
