Howdy,
My PX4 seems to boot correctly, but after the startup tune I can hear a very quiet series of four beeps coming from the PX4. To be clear these beeps are not occurring at the same volume as the usual status beeps. I have to basically put my ear to the controller to hear them. I wanted to make sure that this wasn’t an indication of an hardware issue as I haven’t noticed the sound before. The beeps occur while powering with USB or battery, RC receiver connected or disconnected, GPS connected or disconnected, and OBC (Pi 3) on or off.
Thanks in advance
