omnibus f4sd and crossfire, wiring suggestions?

[Yosemite]

tried tx/rx3 and tx/rx6 and no luck. put tx on sbus uart6, ch2 onto rx6 and it all seems to work

i have seen suggestions to try tx/rx3 and tx/rx6 never had any luck

anyone have any experience with this board?

Link to specific board may help. I have a couple RTFQ Omni F4 Pro boards with Xfire, they use uart 1 & SBUS...and have three different ways to connect a receiver (Spek sat plug, servo pins, or small micro JST plug...all uart 1) so it'll work with pretty much anything.

thanks, this one here, wired as shown in photo, rssi, everything works

I have the pro version of that board, it has a plug instead of those pins, and the receiver is set on uart 1 in the iNav configurator no matter which of the spots it's connected. Have you maybe configured it as a non-inverted receiver in the Xfire menus? What firmware are you using...iNav, BetaFlight?

Pic of how it's wired may help too, you're calling it ch6 when it's SBUS & uart 1...so not sure what you got going on.

thanks fyathyrio, it is wired to the crossfire micro as shown, and there is no option for non-inverted in cf menu. channel 1 from the cf is to ppm/sbus uart6 enabled, channel 2 from cf is to ch4/rx6 as shown. this is the diagram from the place i bought it from and matches the board

this is setup in betaflight 3.2.2, latest fw on crossfire.

took it out yesterday and it flew perfect and ventured out 1/2 mile with still plenty left on the rssi

Well, it's working, so life is good! Micro v2 has option for inverted or non-inverted, guess v1 doesn't.

I've been out about 3 miles on 10mW, if you feed link quality into RSSI you'll get a more stable reading.

I saw you succeed to connect a crossfire rx to a F4SD fc !
Maybe you could help me, because I become crazy connecting a crossfire Rx nano to a X220HV with a Eachine customized F4SD card.
Could you tell the wiring and the BetaFlight configuration if you still have this configuration !
Thank you for your help
