I got my OpenROV v2.6 a couple of months ago, and I have it all built.
I'm now starting to test that it's actually waterproof.
Yesterday, everything was connecting fine and I was able to connect to cockpit and run motors.
I removed everything from the electronics tube and put the ROV in a bath tub.
The good news was that no water got in.
Today, I've put everything back into the electronics tube, but now the Homeplugs won't communicate.
I've been reading as many posts as I can about troubleshooting these comms issues, but still can't get it to work.
On the topside adapter, the Power and Ethernet lights are on, but the Homeplug light isn't
On the ROV Board, the TPWR LED6 is Green, HP LED7 is off, ETH LED8 is Orange and PWR LED1 is Green
I've connected the BBB directly to my laptop via Ethernet cable and plugged power directly into it.
I can then connect to 192.168.254.1 without any problems and view the cockpit.
I've installed the Medialink Powerline Utility software and can connect to the Homeplug in the Topside adapter without any problems, but the ROV HomePlug adapter does not appear
I've then swapped the HomePlugs around (i.e. Topside adapter plugged into ROV and vice versa)
When I run the MediaLink software this time, it again connects to the Topside adapter only (i.e. the one that was previously in the ROV)
This suggests to me that both Powerline Adapters are working, but aren't communicating.
I've reset both adapters to factory settings in the software, but to no avail.
I've also tried using their reset buttons, again with no effect.
Does the TPWR LED6 light on the ROV relate to power to the HomePlug?
(If I unplug the ROV HomePlug, that doesn't light up and more, so I assume that's what it is)
I assume that the ETH LED8 light relates to network connectivity between BBB and HomePlug. Is that correct?
I'm currently using the supplied ethernet cable to connect the BBB and HP, but I've tested it in the laptop and it appears to work fine.
My final test was to check the power level of the ROV batteries.
With the BBB plugged into the main board, I've connected the ethernet cable to my laptop and powered it up.
When I connect to the Cockpit this way, it shows 11volts.
Should that be enough to power everything?
If you have any ideas how to get these Homeplugs to connect I'll be extremely grateful
