Can't enable sbus out in plane airframe

PX4 Autopilot Configuration & Flight Modes ⚙️
1

Hello, all.
I need to have sbus out enabled on my pixhawk. Using SPPM in on a fixed wing, but need that sbus data for another auxiliary controller.
Parameter shows in red if changed to enable. Even if I change it manually, I appear to have no output from sbus out.

I think like me many people don’t know the answer to the question that you asked. So You need expert advice. If you are also feeling the same, then contact Apple Customer Support. They might help you out of this situation.

Were you ever able to solve this issue?

Personally I have no problems with SBUS out on PX4 1.9.2 with Cube. Only thing to notice is that SBUS function outputs only 8 IO PWM channels. AUX1-AUX6 are not mapped to channels 9-14 in SBUS output.

I am using 1.10.1 on a Pixhawk 4 - Using Qgroundcontrol, I set the PWM_SBUS_Mode to 1 to enable SBUS out and it does not seem to have any effect.
