I bound the Rx to Tx fine. I can see solid green light on Rx. Also Tx is showing SNR, RSSI etc fine. If I turn off Tx, the solid green light on Rx becomes blinking state (another confirmation for binding is fine).
Configured Rx as Serial and provider as IBUS in BF. Also configured UART6 as Serial Rx.
Issue is Receiver tab in BF does not respond.
Also tried wiring IBUS wire to UART1 and no success.

The very same setup using my old Flysky FS-RX2A Pro V1 works fine.

I tried the Rx on another F4 FC (Omnibus F4 pro v2) Running INAV and all works fine.

Any thoughts?

Also tried flashing INAV on the FC and Rx does the same behavior.
FC is not compatible with this receiver?

UPDATE - Using INAV. I was able to get Receiver tab working.
I bound to a new model on Tx and it worked in INAV.

UPDATE - Issue resolved in betaflight too.
I had to use UART3.

On your FC, I think RX6 is inverted meant for SBUS.

Had tried UARTT1 also and no success. Which is where my previous flysky rx was connected.
Is there a way to find out which are uninverted UARTs?

Here is the wiki. Could have saved you some time if you have read the wiki. Flit10 only works on RX3 as you already figure out. SBUS pad is inverted and UART1.
