 # Protocol Compatibility
-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.
+- Make sure LoRa sync word and other LoRa parameters match
+- **Client** should be interoperable with other clients, which transmit raw text APRS messages if bluetooth client sends them in this format to the modem
+- **Server** supports only classical `AX25` frames over LoRa (as defined in http://www.aprs.org/doc/APRS101.PDF page 12). It should enable interoperability with classical Linux APRS software, such as Xastir with `kissattach`. Some LoRa ARPS implementations transfer plain text APRS messages over LoRa, as a result **Server** will not be able to process these messages and gate them to APRS-IS, also clients won't be able to decode messages gated from APRS-IS to RF by the server
 
 # Alternative Linux Setup
 It is possible to use modem **in client mode** with other generic Linux ax25/aprs tools, such as `xastir`, use next procedure to set it up:
