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, you can recall previously configured devices and configurations.
Click "Start Configuration", then the configuration items appear. After all items are configured accordingly, click the "Create Config File" button to download the configuration file.
The file must then be copied on an SD card or USB pendrive, formatted with FAT32. Insert the card/pendrive into the device, then apply power or reset it. The configuration will be applied automatically.
For details, refer to the manuals of the respective device: https://flarm.com/de/support/handbucher-dokumente/
