Hi, I just got a new FC (mamba f722 app) and everything works except my RX.
It is binded to my qx7 taranis but it does not move in betaflight.
Please help. (Sorry for my bad english and i am a beginner in fpv)

I attached a picture of my wiring and a dumpp of my Betaflight.

Run the following commands in the CLI and then check for stick movements again in the Receiver tab...

Code:

set serialrx_halfduplex = OFF
save

it didn’t change anything

I have no idea why Diatone insist on putting a dedicated "F.Port" pad on their F7 FC's because an F7 MCU can natively handle inverted signals on any standard TX pad. Having a dedicated "F.Port" pad just causes unnecessary confusion because no-one knows whether or not they have put a (unneeded) hardware inverter on that connection.

Because neither the original settings you had nor the updated ones I provided worked, it suggests there is a possible issue with UART5. I therefore suggest you move the F.Port wire to the TX1 pad on the FC and then run the following commands in the CLI to see if using that UART works instead.

set serialrx_halfduplex = ON
set serialrx_inverted = ON

It isn't working... maybe a RX issue?

Is your QX7 the ACCST or ACCESS version? And how are you binding it to the R9 Mini RX? Are you using the ACCST D16 or ACCESS protocol?

i have the ACCESS version and i used the ACCESS protocol

Have you enabled (ticked) the "F.Port" option for the receiver on your QX7? You need to do that if using the ACCESS protocol. See the following post for how to do that...

I ve already done that

Try re-flashing the firmware on the R9M Mini to the latest version. Also make sure your R9M module is up-to-date with the latest firmware version, and make sure the ISRM module in your QX7 is flashed to the latest ISRM firmware version as well.

The R9M mini and the R9M module are up to date but what is ISRM?

ISRM is the internal module used on the ACCESS version of the QX7. You can download firmware for that from the link below. The latest version as of today is v2.1.6 (dated 2021-02-03).

It still doesn’t work

OK, at least you are on the latest versions of all the firmware so we can rule firmware out as being a cause of the issue.

If you go to the Channel Monitor page on the LCD screen of your QX7, do you see any movements of the bars on the LCD screen when you move each of the 4 stick axis?

yes, the axes are moving
