I’m try to setup VTX power control on KakuteH7v2 + Atlatl HV V2 + 4.4.0-dev:
SERIAL3_BAUD 4 # 4800
SERIAL3_OPTIONS 4 # HalfDuplex
SERIAL3_PROTOCOL 37 # SmartAudio
VTX_BAND 0 # Band A
VTX_CHANNEL 7
VTX_ENABLE 1 # Enable
VTX_FREQ 0
VTX_MAX_POWER 800
VTX_OPTIONS 0 #
VTX_POWER 200
but it not work. How i can see debug message like this:
bool AP_SmartAudio::init()
{
debug(“SmartAudio init”);
?
