Lost Heartbeat on System


(Todd Sparkes) #1

I am receiving an error code "MYGCS: 255, Heartbeat lost"
This has happened a few times now.
Can anybody tell me what this means and how to fix it?

Thanks

Hello,

This means that the autopilot on the ROV has not received a HEARTBEAT message from QGC for 2.5seconds. QGC emits heartbeats at 1Hz.

If you see this message it indicates there was some transient failure in communication between the autopilot and QGC.

You should make sure that the tether conductors are well seated in the interface boards, and try a different power supply for the topside board.

Thanks Jacob. I updated Pixhawk and it seems to have fixed the problem.
