 # Protocol compatibility
 - Make sure LoRa sync word and other LoRa parameters match
-- **Normal/Client mode** should be interoperable with other clients, which transmit raw text APRS messages if bluetooth client sends them in this format to the modem
+- **Normal/Client mode** should be interoperable with other clients, which transmit raw text APRS messages if KISS client sends them in this format to the modem
 - **Server iGate** 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
