I was trying to connect back to mission planner to make a change and the Pixhawk made the usual sounds and lights and then went solid red and now safety switch light will not work. I also can’t connect to the mission planner.
Not sure this is 1 or 2 issues. I would check V input to make sure something hasn’t changed causing the PH to get hot. Second I would check COM Port to verify right one is active or try different USB cable.
Think I might have fried my pixhawk bu accident by connecting a 6S battery to a 3S power module. I makes the start up tones and then the led goes to solid red and I don’t have a safety switch anymore. Also it will not connect to the mission planner.
