Mro control zero H7 CANBUS


Has anyone used a Hereflow optical flow with a MRO control zero h7 before? If yes, may i know how you made it work?

My flight controller does not seem to detect the hereflow sensor even after following the instructions from the following websites:

I constantly get a Bad Optflow Health error and my arducopter version is v4.1.0-dev


ArduCopter 4.1.0-dev is very very old

Please update to either ArduCopter 4.1.5 stable or to ArduCopter 4.2.0-beta3

And if you are not a developer you should not use -dev builds.

I have updated to 4.1.5 stable but it is still unable to work, the bad optflow health error is still there

Can you update the FW on the hereflow?

Do i do that through UAVSCAN on mission planner? I am unable to see the hereflow through UAVSCAN, the only device that i can see is org.ardupilot:0 and that has an ID 10

WIth reference to my previous reply, this is a screenshot of what i see on mission planner


If anyone would like to know, I managed to get the Hereflow sensor working when i connected it to CAN3+/CAN3- ports of the H7 OEM.


How to use CAN3 port?
