Hi @Teggles -
Can you confirm the issue is still happens only when the ROV is in the water? Or just when armed in depth hold mode on the bench? Do you have depth readings from the pressure sensor when diving in other modes?
Can you share a vehicle log from the Autopilot Logs menu that has this behavior captured? Thanks!
Hi Anthony,
I will throw her in the water tomorrow and post the logs.

Hi Anthony,
Apologies for the delay but the weather in the UK has been appalling recently. Too rough to go offshore and so much flooding onshore - its difficult to get near any deep(ish) water.
Here is todays log as I managed to get near a river:

Yes, it works much better in the water. Depth hold is slow to stabilse at a selected depth, but when it does it holds it very well. I am still having comms drop outs and loss of video. A few seconds each time. On 1 occasion I lost the controller but was able to arm/disarm via QGC. So still something strange going on.
Once again thanks for the help,
Terry.
Resolved, lowered the telemetry rate to 8 Hz. All working fine now.

Hi Terry -
If you continue to have camera issues, checkout this technical bulletinā¦
Hi Terry,
We are experiencing exactly same issue with vertical thrusting making a connection lostā¦
But I donāt really understand how do you changed the telemetry.
Can you help me out a bit more on how didi you do it?
Thanks,
Hi Mathurin,
I am travelling around Europe this week but not with the ROV. As soon as I am home I will look at QGC to see exactly how I changed the telemetry rate.
Terry.
As a first port of call, there are some power management settings you may wish to try out.
QGroundControl allows changing the stream rates in its MAVLink settings.
