APM2 GPS Red LED and data help (CRASH REPORT, ANYONE ELSE?)

HI everyone,

I have been struggling with the APM2 that I have just installed and have been trying to fly in Auto and RTL modes. I do have the plane flying great in the stabilize mode and the fly by wire mode also works.

When I switch the plane to RTL or Auto mode the plane does fly itself (circle) and hold altitude but it does not go to the waypoint locations and it does not circle over the home or launch point. Every time I have flown I have waited for the blue led to go solid and also the 3Dfix led is solid. I have also connected to the computer outside and in the mission planner it says 3Dfix. I do NOT ever get a red led to stay on. The red led does flash when the board is first powered up but then has never stayed on solid like is says it is supposed to. See the link.

That brings be to my next problem. It was suggested to me to look at the data log and see if there is an actual gps lock. When trying to look at the data log in the mission planner I do not see any horizon changes, speed or altitude changes. It does say the log is playing but I am unable to see any of the planes functions.

I have been struggling with this for a week now and do not know what to try next. If anyone could give me some suggestions that would be greatly appreciated.

Thanks

Ryan

Thanks for the pictures. I think my next plane to fly the APM will be that exact one.

help

i have pasted this below from the Appendix section on lights of DIY on the colour of ABC lights on APM2, but in the colour pics on that page the colour of A on APM1 is Green and in APM2 is Red, so i hope, that what is written for A and C in text is correct....

 

APM 1 and APM 2 LED meaning

LEDs: Behavior:
Power On when powered
TX Shows data coming in USB/FTDI port
RX Shows data going out on USB/FTDI port
A C Fast flashing while calibrating gyros, then pause, then rotation flashing (about 45 seconds total).
A Flashing = Code loaded or loading, ready to arm. Solid on = Armed, ready to fly (arm by holding rudder stick full right for 4 secs)
C GPS lock - C Flashing while waiting for GPS lock; Solid with GPS lock.
A C Solid A and C and you are ready to fly

Hi,

I found the information about LED description here at the topic.

Because I like to check my APM2 about a fault. At the description I found out that LED A B not flashing.

My freind have the same APM2 and it is still working.

If it possible at any case over terminal or Mission Planner to activate the LED for testing?

Maybe you can replay with PM to send me a link where I can found more information.

Also I have some points which are not logical from me. Drift and shift left some times with no imput from the RC.

Maybe the Gyro sensor have some defect or working not fine :( At the moment I didn'T know what I should can do to found the root cause to fix it.

Thanks.

Regards,

Thorsten
