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.
