Exit narrow band mode using firmware update?

[evilC]

It seems to me that there is a capacity for people to get locked out of a VTX because narrow band is set and they only have a VRX.
Am I missing something, or is there a way out of this scenario?
If there is not, would it be possible to craft a firmware which resets the VTX to some safe defaults?

Now with vrx's firmware rev 13112023 with narrowband support this is still necessary?

[evilC]

I guess maybe not, but I did see recently so that there is actually a firmware which does do it anyway

Updating the firmware will not affect the parameters that have been saved. Unless special firmware is used, saved parameters are initialized at power-up.

Just #define RESET_CONFIG to generate the special firmware.

I have seen a number of users locked into narrow band without realising it, and assuming they have a defective vtx.

Would it be possible to add the ability to switch in and out of narrow band by stick commands ?

This would avoid the need to recompile and reflash firmware as part of diagnostics.

How do you think we should design a new stick command to reset all configuration?

I realise there are a number of challenges here, but I think the demand has increased judging by the number of people who seem to be unwittingly locked into narrow band.

One good reason not to do this with sticks is that we really do not want to allow people to accidentally reset all their settings.
Another issue is that most/all movements are already employed in iNav/Betaflight/HDZero positions.

The only real way would be to modulate them differently.
I note that Quicksilver uses a sequence of 3 movements in a certain direction for example.

I understand stick movement would be a challenge, but raise this point to try and get some discussion of some way to resolve
the underlying problem.
