PING 360 “stalled state” how to reset while underwater

Blue Robotics Software Ping Viewer

Hello,
Using BROV 2 using latest update.
The ping 360 sonar (running via USB serial-bridge to UDP :9092) seems to get locked up if there is a temporary failure of the either net connection.

Is there a way to power cycle the USB port, rather than having to power cycle using the battery?

I’ve tried all the built in reboots, but nothing works.
I’m hoping to avoid a scenario, where the ROV is in the water and ping 360 fails/locke up, and have to recover the ROV to power cycle.

Thank you in advance!

Hi @oceanq -
You may want to use the latest version of PingViewer to update the Ping360 firmware - you will need to connect the unit directly to your computer via USB to accomplish this.

Can you elaborate further on the failure of your ethernet connection? Is the Fathom-X link light going out? Eliminating this fault seems the best path to normal operation.

Power cycling a USB port is only possible for some devices, and in the case of cameras tested by the Blue Robotics software team, made no difference in terms of resetting the device…

Thank you!
I’ll give it a try when I get back on land.

Hi @oceanq,
I’d like to share my experience with ping360 locking up, as it may help.

I noticed “locking up” a while back and haven’t been using my ping360 much since, so the firmware update mentioned by Tony may have fixed it.

To recreate the locking up behaviour I experienced, you have to power cycle the ROV (e.g. change battery) while pingviewer desktop is connected.

FYI. I use my ping 360 ethernet connected.

Also, the effect of the locking up is much more noticeable if you change the settings eg range and speed before and after the powercycle.

See below GIF - Is this the same behaviour you’re seeing?

Solution for me:
It took me a long time to realise I just have to go into the connection manager and reselect the device after each powercycle.

Watch the GIF all the way to the end to see it get back to normal after re-connection.

Change settings - Power cycle - change settings

Hi @XYZEng
For older versions of PingViewer, the behavior you’re seeing is expected. To be clear, the device isn’t “locking up” - it just needs the connection negotiated after every power up sequence. You may see the desired behavior if you use the latest version of PingViewer! This version also lets you update the firmware (via USB connection only), which improves scan speed by a good margin!
