I have a homemade drone with a cube black, the latest arducopter, and a here 2 GPS. I’ve been running this drone for about 3 years with out any trouble. Today however, my battery got really low, and after i switched it out, I cannot get the ESCs to stop beeping.
Normally, the pixhawk starts up, plays a tune, and then I push and hold the button on the here 2. Now the Here flashes normally, and the hardware safety works as expected, but the ESCs never play their 4 or 5 beeps to get ready.
I’ve tried updating the firmware on the pixhawk, and I’ve tried a different here 2 puck. No luck so far. I’m honestly not sure if this is a pixhawk problem, or an ESC problem anymore. Nothing obvious seems to have changed.
Any suggestions would be greatly appreciated.
