Hello, Attached is a log from Cockpit. I am continuously losing connection to the vehicle during actual dives. I don’t see this happen during bench testing. Running : Seaview Systems Fiber Optic Cable Navigator Blueos 1.4.3 Ardupilot 4.5.6 Cockpit 1.18.2 Network Test (Tether diag shows “0”) …

Hi @minskim88 - Thanks for the logs! It seems this build really has improved things: [image] The team will continue testing and work to get it merged in! Thanks for your patience and time in testing this - considering the issue resolved!

Hi @minskim88 - It seems the feature is only available in the beta, not stable channel. Easy enough to update! [image]

Thanks Tony, Is that the latest beta? I will give that a go. Also I‘ve been reading about mavlinkserver. Currently the ROV is set with mavlinkrouter. What would you recommend? Switching to server option? I’ll try get the dumps tomorrow. thanks,

Hi @minskim88 - Yes, that is the latest beta release I linked. Trying mavlinkserver, and the latest BlueOS 1.4.4 beta (which is very close to release) would be a great troubleshooting step as well!

Hi, since the first release of cockpit I wasnt able to do only one dive without heartbeat lost. Dry tests on the workbench are OK with less heartbeat issues exept some forced resets alerts. I use the desktop app because the browser version is too laggy. I still use QGC for operation in water. Sinc…

Hi @schleitaucher - That’s quite a well aged ROV! :wine_glass::clinking_glasses: A pi3 is definitely worth upgrading from! Otherwise QGC / legacy Companion OS may be a better fit for the Pi3/Pixhawk… I wouldn’t expect temperature issues if you use a heatsink - the Navigator comes with one, and …

Thank you for your input @schleitaucher I may just go back to QGC, but really like the layout of the Cockpit. My build is Pi4 w/ Navigator so it may be little different. Really havent had a time to go out again. Will let you know if QGC works better. Thank you,

Hi Tony, Not really finding the time to go out after the last one. But here is at least a bench testing that I can give you. With Cerulean DVL extension ON (including rangefinder). cockpit-mavlink-dump-2026-07-31T17-32-33-542Z.jsonl (3.2 MB) cockpit-mavlink-dump-2026-07-31T17-30-20-287Z.jsonl …

Hi @minskim88 We’re testing to see if the issues you’re having are related to the problems found in this pull request . Assuming you’re using standard 32bit BlueOS, this ArduSub firmware file attached here can be flashed from file under autopilot firmware. ardusub_udpfix_32bits (2.2 MB) In order t…

Ok will give a go. Will report once done
