Hi Jeremy,
Thank your for the logs, they are really helpful.
Can you describe a bit more about your setup, do you have a normal BlueROV2 ? Any further information can help us to identify the problem and maybe replicate it.
From the log, it really appears to be an EMI from the power supply, the messages are indeed matching the protocol checksum, so everything that you are receiving from Ping360 to Companion is rock solid, the problem appears to be in Ping360 power source.
We are going to do some analysis in your log files, and get back in touch asap with news.
