    Having an issue with a new build.
    Part list

    Omnibus f4 pro fc
    Frsky r-xsr rx
    Frsky taranis x9d tx
    30a littlebee esc's
    Motors are not here yet
    I'm trying to set it up in betaflight, but having issues with what uart ports in Port tab. I can't get any stick input from tx in the receiver tab of betaflight. Rx is bound. New to the frsky radio. Does it need to be armed in betaflight? The camera ,trx and osd I'm using does work with my googles when I plug in a battery.

    Something I'm missing? I did set up the receiver in the configuration tab. Really not sure what uart port needs to be enabled in the port tab to work with my Rx. Pretty new to all this.

    Did flash latest firmware to my FC. Saw a vid where someone had to use an older firmware to get his to work, but don't know what version.

    Thanks for any help.

    First, is your receiver showing a solid blue LED , indicating it's in SBUS mode, not CPPM?

    In configuration tab under receiver mode, set to RX_Serial. Under Serial Receiver Provider, set to SBUS

    Modes tab: As this is the Omni F4, I'm assuming it's showing UARTs 1, 3 & 6. Enable Serial RX under UART 3 and you should be good to go.
