Title: Attitude : error - Attitude info is not shown
Post by: mettinoktay on February 13, 2017, 07:42:29 pm

After a crash, a red cross appeared on the ATTI box on the System Health panel and quad refuses to arm. The same problem occurred a few months ago and I managed to fix it by reuploading the software but this time it is persistent: the error has remained after reuploading the software.

I crashed on soil not that hard at all (the frame was still one-piece). What might be the problem here? Is it really possible that the G-shock has malfunctioned the gyros?

Board info

Board: CC3D
Firmware tag: 16.09
Firmware date: 2016-12-12 23:37
BL version: 4

Be sure you do not move the board and wait Attitude initialization.

The AttitudeSettings > BoardSteadyMaxVariance value can be increased if your sensor becomes noisy.

Thanks for the help.

How long does an Attitude Initialization take? I have been waiting for a long time now (~30 minutes) without moving the board; the error still remains.

Board wait to be steady for a few second and do a Gyro init.

If sensor become noisy he never think the board is steady > increase  BoardSteadyMaxVariance value

I see that your input is red.  I would fix that first.

Look on the input page and see if you can manually tweak it.  If not, run the transmitter wizard that you will find there.
