And channels 1 to 8 with telemetry in the radio.

I am using the RX-8 recv and Spirit 2. Short history, I upgraded my flybarless spirit gen1 to spirit 2 on my Goblin 570.
OpenTX Integration was working with original spirit, since upgrading to spirit 2, exact same setup as before openTX integration is not working anymore. Will wait to firmware 3 comes out, most likely will be fixed then.

I am using OpenTx 2.3.7 and on my spirit pro the 2.8 version and telemetry and integration is working with my R-XSR receiver.
Which versions you are using? Perhaps your versions are not working together.

Glad it's not just me that is running into this issue. I have all the latest firmware installed on my radio, and have tried a few receivers now in Access and D16 mode, and I still cannot get any data back to the radio..
Serenus... May I have a picture of how you have you little reciver wired up.. I have one on my Oxy 4, and directly soldered onto the sbus pad so I didn't have to use the inverter cable, but I haven't figured out how to wire it for telemetry?

Have you fixed your issue? Sorry I have not read you post. I am not using the Pad. I am using the connector and the integration cable. Parhaps the integration cable is not doing the same as the pad on the R-XSR is doing.
