What is LED B on the IMU/Oil Pan used to indicate?

During initialization and runtime, LED B is not lit. It never flashes.I am bench testing the GPS and Wireless Telem. I do not have all servos hooked up.The doc doesn't say what the individual LED's mean, only that B should flash then go on solid.Thanks. Preston.

  • Hmmmm This concerns me. I am running 1.0 and it never goes on, not even dimmly (I turned the lights off to double check). From your replies, it isn't monitoring anything specific, just used as a Blinkenlichten. I wonder if it is any good.

    I'll have to research the pin and see if I can turn it on at all.

    The LED behaviour varies with the firmware you are running. 


    If you are running APM 1.0 then LED B should flash with the other 2 during ground start.  After ground start completes it should go solid indicating the IMU has been calibrated.

    Not sure what the LED means but is it not flashing while it calibrates? it can be dim when next to the others flashing.
