Ardupilot with ArduIMU correct LED behavior

Posted by Nathaniel Caner on April 9, 2010 at 5:30pm
What is the correct behavior of the LED's on the Ardupilot board (red board) running code v 2.6 beta,
with the Ardushield V2 (blue board), and an ArduIMU+ V2 code v 1.6.

After initial startup the YELLOW led is solid and the BLUE gps lock led is blinking this is the same behavior on the Ardupilot and Ardushield boards. The ArduIMU has a steady BLUE led.

Shouldn't the BLUE led on the Ardupilot and Ardushield boards stop blinking and turn steady once the ArduIMU board establishes a gps lock?

    After all the initial flashing during ground start ArduIMU and ArduPilot should have solid blue lights, ArduIMU will have a (mostly) solid yellow light if you are using the speed filter and the uav is at rest, and the yellow and red lights on ArduPilot should toggle with your mode switch.

    If you have solid blue on ArduIMU but blinking blue on ArduPilot it means that you have a communication issue between them. Check your wiring. Check that you are using binary messages with ArduIMU and the correct GPS_PROTOCOL value in ArduPilot Check that you are using compatible code versions (ie get the latest of both sets of firmware).
