Using SoftRF firmware to turn t-echo to FANET device.
Plug in T-Echo to computer, double click up button, drag and drop .uf2 file after extracting the downloaded zip file to get SoftRF: Moshe version https://github.com/moshe-braner/SoftRF/tree/master/software/firmware/binaries/nRF52840/SoftRF/MassStorage
Click the bottom button till you get to the summary screen. Double click here to go into configuration menu. Tap the touch button at the top once to change value and double tap to save. This feature is in Moshe's SoftRF. On https://github.com/lyusupov/SoftRF you can use SoftRF-tool android app, see detailed guide link.
Set your aircraft to Paraglider, Protocol to FANET and Region to IN. Bir has one GXAirCom Fanet ground station, Fanet range is not as great as Meshtastic so coverage is limited at this time.
There's flarm sensor option in xctrack, but didn't see where it shows up in interface. Xcsoar should work as shown in Quickstart guide: https://github.com/lyusupov/SoftRF/wiki/Badge-Edition.-Quick-start.

Please note that live tracking will work in only at places where there is ground station or the device is paired with a phone with data connection and app that supports live tracking.
Same procedure to get back to meshtastic using https://flasher.meshtastic.org/ latest alpha uf2.
