Hi. can anyone help. I have video and OSD so I think it is wired correctly however not all features seem to work or if they even should on a camera like this
Camera/VTX = https://www.unmannedtechshop.co.uk/product/thefpv-sa-micro-aio-fpv-camera-and-200mw-vtx/
Flight Controller = Mamba F4 Mini Stack
The FC Uart Wire is connected to the TX3 on the flight controller
On the ports tab on Betaflight Smart Audio is enabled on Uart3
When I use the sticks to open the OSD menu it opens up fine in the OSD as it should and I can navigate that how I would expect.
However any changes made to VTX settings like power or channel make no difference to the VTX should I be able to change these settings in the OSD
Thanks in advance
