Was running Blue in pool testing the new software upgrade. Spent weekend upgrading the pixhawk and ardusub.
Working great until it lost communication and shut down. Battery still has power and tried fresh battery. System totally down.
Please any ideas on where to start troubleshooting??
Thanks,
Bill
Hi @wjwalker -
Sorry to hear of the problem. I’m assuming no leak occurred?
Do you observe any flashing lights on the Pixhawk? How about the raspberry pi - there should be a solid red and occasionally flashing green neat the front of the enclosure by the dome?
Do you see any flashing lights on the Raspberry Pi’s ethernet jack?
Is the Fathom-X Link light on alongside the Power light on the port side of the main enclosure? And also on your FXTI (topside) box?
Do you hear the normal start-up sounds when you connect a battery?
What were you doing before you lost communications? By shut-down, do you mean you lost connection on your computer, or the lights all went out!?
Tony,
It was working so well that I tried some speed testing. Pool water is 70 deg.
Everything is dead, no lights, no startup sounds. My thought is power so will start there. Is there fuses, circuit breakers, some type of protection??
Is there logs? I restarted QGC. I found one binary log, but could not load it in QGC analysis. Only option was to load from ROV. Do you have a test program to read it??
Do you have a super user in FL that could work on it??
Thanks again
Bill
Hi @wjwalker -
Logs are stored on the vehicle, you’ll need to get it up to retrieve.
There is no fuse, but older units used bullet connectors that could de-solder themselves with heavy use. Start by opening the main 4" enclosure, and with a battery conneted check for voltage on the two rails on either side of the enclosure. If none is present, trace the path from the battery cables looking for damage.
I’m not aware of any service providers in Florida!
