9XR PRO protocol with XJT and R-XSR (S-BUS)

[moraitis_george]

Dear all,
I am using 9XR PRO in several of my models.
Recently I made a new quad with a R-XSR receiver and a XJT module (as my old DJT couldn't be paired).
In the time that I waited the module to arrive, I borrowed a Taranis QX7 from a friend, where I successfully bind it in D16 mode. The bind and the setup in betaflight was perfect, as everything was working, including the telemetry also.
Today XJT module arrived and I begun the setup. Whether I am running the stock firmware (on my TX) or the most recent er9x, the only way that I can see TX signals inside Betaflight, is through PPM protocol (choice in my TX). As my knowledge in these stuff is small, I think that PPM is slower that S-BUS, or this option doesn't have anything to do with what I am saying.

I don't know much about FrSky but one thing that crops up a lot is the firmware on the transmitter needs to match the receiver!!! Might be worth asking your mate what fw is running on his qx7, there is EU and non EU stuff etc. Then I guess, and it is a guess you have to update the module to run the correct FW?

PPM is slow and I don't think it's capable of telemetry.
