 - 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 KISS client sends them in this format to the modem
   - NB! For interoperability with other APRS LoRa implementations, which do not use AX.25 frames, but use text based messages, need to use **TNC (plaintext TNC2)** APRSDroid connection protocol and set `cfg.EnableTextPackets/CFG_TEXT_PACKETS` to `true`, this way KISS will be disabled and TNC2 compatible mode will be activated. This option should also be activated if you want to use modem with Bluetooth terminal applications. 
- - For interoperability with lora-aprs project need set `cfg.EnableTextPackets3/CFG_TEXT_PACKETS_3 to `true` in addition to `cfg.EnableTextPackets/CFG_TEXT_PACKETS`, as lora-aprs uses 3 byte prefix for packets ('<', 0xff, 0x01).

 - **Server iGate** by default supports only classical `AX25` frames over LoRa (as defined in http://www.aprs.org/doc/APRS101.PDF page 12, see section below). It should enable interoperability with classical Linux APRS software, such as Xastir with `kissattach`. 
   - NB! Some popular LoRa ARPS implementations transfer plain text APRS messages over LoRa, for this mode operation need to set `cfg.EnableTextPackets/CFG_TEXT_PACKETS` to `true`, in this case iGate will transmit, receive and digirepeat text based APRS messages instead of classical AX25 frames.
