Matek VTX-HV 40CH Betaflight Controlled Stack VTX

[rotorx]

Hi running this vtx on Racestar starf4s using softserial on reconfigured led strip pin for
smartaudio smartport connected to uart 6 the only other uart using xsr with inverter hack
smartport and lua scripts working fine the problem i have is that smartaudio and lua is not
working. But when i first configure quad it works fine but then stops. Upgraded to 3.2.1 tonight
started working then stopped, just altered setting (only enabled rssi) in betaflight then started working again
til i restarted no smartaudio, vtx is working fine. Dont know what firmware is on vtx bit reluctant to do upgrade
with ftdi as ive bricked first one I had and yes was connected ok as per instructions.
