QCZEK LRS – SPORT TELEMETRY

Starting from version 1.90 QLRS support conversion mavlink encapsulation telemetry data to FrSky smart port telemetry (on TX module side) to make possible displaying essential flight data directly on radio screen. There is no need to use any additional hardware, except wire connecting M0 pin with sport Taranis’s pin inside module bay (blue wire on phone below).

From version 1.91 you can connect QLRS directly to FrsSky RX and together with SBUS input use it as a relay. When slave sport is in use you get rssi as APID_CUST_RSSI 0x04B0. Please note that you have to setup telemetry type to 4 – Mavlink + SPORT SLAVE.

And it required additional 1k resistor …

Unfortunately M0 pin is used for LED control, so LED will only blink according telemetry data stream.

Next you need to set telemetry encapsulation on RX side, and to new mode “Mavlink enc. + SPORT” on TX side.

Now you just need to power on you plane, turn on Taranis radio, and discover new smart port sensors. Please note, that you should first check “Ignore instances” option, and wait for GPS fix (if there is no fix, not all telemetry data will be discovered).

Now you can use your favourite lua script 🙂
