ESC Blinking Red


#1

We have an OpenRov 2.8. We just finished testing the ROV in a pool. The ROV flew fine but when we tried it the next day the Port ESC is blinking Red? The other ESCs are green and the motors work.


#2

It’s hard to say for sure without knowing how it’s blinking. The Afro ESCs that we use signal their error codes through blinking of the LEDs- you should be able to find a reference to that on-line somewhere. Absent that information, I would thoroughly check all the wiring associated with that motor, making sure that there are no short-circuits or open-circuits anywhere in the wiring.

Let us know how what you find out.

I am away this week, I have another person working on it. What we suspect
is that it may be a wiring issue with one of the motors because when we
connect another BB/Arduino we get the same response from the ESC.


#4

We have 1 of our 4 ROVs working, the 2nd we have been trying to launch is
exhibiting the following behaviours:

ROV pinged successfully at 192.168.254.2
3 Green speed controller lights
Blue light from Begal Bone
LED 4 BRX Blinking Orange
LED 1 Pwr and LED6 “HPWP” solid green
LED 7 “HP” and LED 8 “ETH” solid Orange
all other LEDs off
Camera lights blinking white
The cockpit cannot be reached “too long to respond”

Ideas?

@Tom_MacIsaac:

I would drop a line to OpenROV support. I think its just support@openrov.com. Make sure you reference this thread and provide them with the model # of your ROV (2.7, 2.8, etc.). Your LED indications seem correct, must be some subtle software issue.
