Hello,

I am having issues to bind the XM+ to Jumper T8SG V2. Its first time I am going for an FRSky receiver, I only had Joysway, AFHDS 2, SLT and Spectrum ones with my jumper.... I just cant get them bind.

What I tried: Common for all: Select Protocol in Model config to Frsky.
Variant 1: Take the receiver, keep the only button pressed, plug it into power. Red LED starts to blink. Press Bind on transmitter. Runs into timeout, no blink change on receiver.
Variant 2: Plug in the receiver, press the button shortly afterwards. Green led blinks 1-2 times, then out, red led is blinking. Try bind on transmitter. Timeout, receiver keeps blinking.

What do I do wrong?

PetrOs,

Protocol is FrskyX!

Power the receiver button pressed, then select bind in the transmitter.

Thanks, quite sure I tried this variant already but will do once more in the evening. Could it be that as I give the power directly over the flight controller port, and that disturbs?

Look what firmware is on the XM+ and select that (EU/FCC) under FrskyX Protocol Options!
If RX and TX are too close to each other, the binding does not work either! So walk away sone Meters!
At last you can try to change Freqfine Setting in Procol Options (I have -40 there)!

After about 20 tries and moving the receiver from my FC UART directly to PDB, I managed to bind. Thanks!
