The LED mode set up descibed here http://copter.ardupilot.com/wiki/nav-leds/ is incorrect. LED mode as described here is correct http://ardupilot.com/forum/viewtopic.php?p=7898#p7898. It seems the method on version 1.2.91 of mission planner, at least, has been moved and options changed to only allow it to be set from the full parameter list and it has no options visible. Can this option be returned to its previous state as described in the guide for ease of use, or the guide updated?
Ah, thanks for the report. This is surprisingly difficult to fix actually because the problem is that the mission planner is taking it’s parameter information from ‘master’ which has moved on from AC3.1…I’ll bring this up on the dev call and we can probably do something.
