OpenVTX does't work with Ardupilot and PX4 firmwares

mmoustache opened this issue a year ago · comments

Hello mates. There is an issue about OVTX work with Ardu and PX. Other VTX's are working OK by using SmartAudio protocol, port speed 4800 baud. When i connecting OVX306 to same port, OVX306 enables Orange LED and Slowly blinking by Blue LED, but there is no video in receiver and no control by firmware. Tried to change baud rate, switch to MSP, enable\disable half duplex for this UART, same thing. Tried to solder another UART, same thing. Tried to downgrade Ardupilot and switch to another board, same thing, not working %( Maybe any ideas you have how to fix that?

I also have strange behavior with iNav. Betaflight works well with msp so I'm stuck with betaflight for now. The iNav developers think the issue may be with iNav as they index the settings. Don't know why that matters. I badly want to try and debug myself but just not savvy with cmake c and working with microcontrollers. Ugh!
