Is this protocol not working anymore? I'm using T-motor F7 HD & F55A Pro II Stack/ Combo for DJI.
I did run the cli command "set sbus_baud_fast = ON" and the option in Betaflight 4.1 and Goggles are not showing up.

This is the link for the DJI remote. I don’t think it should have any effect on the goggles. What exactly do you mean by not showing up? No picture or no OSD items?

Sorry I wasn't clear, the option to chose the DJI HDL protocol is not available for selection on both the goggles and betaflight 4.1 under SBUS, even when you have the fast sbus_baud_fast enabled.

yeah i'd like to know where this went as well. i have baud fast enabled and i just use sbus. not sure if i'm using hdl in this way or not

Hi there, you are recommended to refer to this post: https://forum.dji.com/thread-198403-1-1.html, hope it can help you, thanks.

You need to have sbus selected and sbus_baud_fast enabled. If this is set and the goggles are set to use the DJI protocol you are using it. If the protocols do not match, it does not work at all.

Thanks, everyone, but it's still not showing. Please see the images attached below and as you can see I don't see the DJI protocol at all.In my DJI goggles the only options I can select under device are normal and sbus baud fast. My control works in sbus baud fast option, but I want to use that DJI protocol (7MS).

If you have SBUS selected, subs_baud_fast = ON set, and selected the right protocol from the goggles. then you are using the DJI protocol. If the goggles do not match the flight controller setting then it does not work. If you are looking at the on screen display latency and thinking that must mean that you do not have it set, that is video latency, not control link latency. The 7ms latency is only for the control link.
