Hey,
I have R9M  module trying to work with R9mini, both accsst and flashed with FLEX
I have wired it as on picture, connecting nTX2 to S.PORT on r9mini (which is flashed with FPORT firmware)
Received binds and sticks input work as long as I set serialrx_halfduplex = ON nad serialrx_inverted = ON
But I have no telemetry. Setting halfduplex - OFF does not help.
Any help would be much appreciated.. seting up R9M i really confusing..

It's possible that the inverter on the FC isn't working properly, or isn't a bi-directional inverter which is needed for FPORT. We've seen this on some other boards (non working inverter or design fault).

What transmitter do you have, and is it an ACCST or ACCESS version?

What type and version of firmware have you installed on the R9 module and receiver?

When you bound to the receiver did you select one of the "TELEM On" options?

Can you please also run both the "dump" and "diff all" commands in the Betaflight Configurator CLI tab and copy/paste the results back here.

Thanks for quick reply,
Its Q7X with ACCST - flashed latest flex firmware from frsky website, R9M module is 2018 version, r9mini latest flex firmware with Fport
I bind with TELEMETRY ON,  radio detects two sensors: RXBt and RSSI so I hear "telemetry recovered" and have RSSI value but so battery voltage etc
Running on emuflight, below is diff:

You actually need the following settings to use FPORT on an FC that has an onboard inverter like the GRP-F4-12A, but you said you already tried that and it's not working which is strange.


This is making me think that there might be a problem with the hardware inverter on the nTX2 connection.

I see that you actually have an R9MM receiver (not an R9 Mini), so move the white wire from the "S.Port/F.Port" pad to the "Inverted S.Port" pad on the receiver, and move the other end of the white wire from the nTX2 pad to the UART2_TX pad.



Then also run the following CLI commands to correspond with that wiring configuration...


Then check to see if you then get both stick movements and telemetry.

/ move the white wire from the "S.Port/F.Port" pad to the "Inverted S.Port" pad on the /


I actually tried to connect like this at the beginning - inverted S.Port to both nTX2 and TX2 and I could not get it working - no stick inout, tried all -CLI -ON and -OFF options.  I`m actually considering flashing ExpressLRS 

I flashed both module and rx to ExpressLRS and connected to TX2 and RX2, serialrx_inverted = OFF, serialrx_inverted = OFF
In works perfectly, including telemetry.
If anyone has similar problem I strongly recommend changing to ExpressLRS.
Just remember to NOT use the inverted pads (nT2 and nR2)

Nice one.

Yes, all the FrSky stuff is a complete mess and it creates far too many headaches and wasted hours for so many people. I think that was a good choice moving to ExpressLRS. All of the ELRS testing is showing some really promising results.

I agree, the whole process of flashing ExpressLRR is clearly explained on github and youtube videos,
there is one firmware version for rx (no accest/eccest, fcc/eu like on frsky),
and you have to connect to radio only first time you flash, after that you can update by USB throught FC using special configurator.
And (as for now) it works way better than standard R9 firmware for latency and stability.

Yes, and ExpressLRS even outperforms TBS Crossfire, TBS Tracer and ImmersionRC Ghost which is really impressive for an open source solution.

While TBS and ImmersionRC can't make use of any ExpressLRS source code in their closed source solutions, I'm sure the engineers at TBS and ImmersionRC are scouring the ELRS code to get some ideas for future version of their own firmware. As long as they don't use any part of the ELRS open source code, they could still replicate some of the same architecture and functionality as long as they rewrite the code as their own implementation. So the increasing ELRS competition may start forcing some of those other systems to become better as well which would be a win-win for everyone.

I have a very very similar problem on the following link, but I'm not even getting RSSI or RXvBAT showing up on my taranis X9D+ ACCST...Ive given up lol. I've looked at Elrs however I would have to do a mod to my R9M ACCST module regarding the baud rates and thats still not guaranteed to work propperly because the taranis might have issues with the baud rate as well...fml.....why must things be so complicated, I upgraded to this radio some time ago for solutions to all my problems but it has just made more, can go buy a more up to date taranis but then Im sure something else will then become a problem.
