 This project is using classical `AX25` frames over LoRa (as defined in http://www.aprs.org/doc/APRS101.PDF page 12) with given LoRa parameters above and `AX25` frames are encapsulated into `KISS` frames when transferred over serial Bluetooth to phone or PC. It should enable interoperability with classical Linux APRS software and `kissattach`. Some LoRa ARPS implementations transfer plain text APRS messages over LoRa, as a result interoperability with this project is not guaranteed.

 - At this stage you can already start using `xastir` or any other application, which can operate over KISS Serial TNC
 - Alternatively, you can setup `AX25` network interface with `sudo kissattach /dev/rfcomm0 ax25` command, but previously need to update `/etc/ax25/axports` with new line as `ax25    CALLSIGN-10        9600    255     1       comment`
