Pixhawk continuously beeping, nothing seems to make it stop

[Valor]

Connecting our Pixhawk board to any source of power seems to create an unbearable beeping sound which voids any potential function such as setting up firmware or connecting the Pixhawk to wifi. All attempts to fix this problem continue to make the same aggravating beeping sound when turned on, and any error code indicating this beeping couldn’t be found. Any ideas on how to fix this issue?

Hi @Valor, welcome to the forum

ArduSub by default expects a Leak Sensor to be connected to AUX port 6. That leak sensor is effectively a ‘normally closed’ switch, which becomes ‘open’ when one of the probes comes into contact with water, so if it’s not plugged in ArduSub thinks there’s a leak and engages the Leak Failsafe.

If you don’t have a leak sensor then you should be able to disable the leak sensor failsafe in QGroundControl on the Safety Setup Page.

I’d suggest reading the three comments in that thread
