[SOLVED] Problem with the Crazyflie

[tobias]

The software is not able to damage the gyro but e.g. electrostatic discharge or mechanical stress are and if the MPU6050 broke it is very hard to tell why.
What software did you flash? You can try flashing the old software again to rule that out. Also as I said I can make a custom version that prints more information from the self-test.

i flashed the cflie-2013.4.bin Firmware from https://bitbucket.org/bitcraze/crazyfli ... /downloads which results in Self test failed.

The strange now is the following: I flashed back to the "Old" cflie_ProductionV2.bin also from that bitbucket page and it is connecting again without problems. Also the Flightdata screen is rotating in all directions i move the flie with my hands.

Hmm, this is really strange. Can you try the attached firmware (rename it to bin) which will print something similar to this:

Code: Select all

MPU6050: Self test gyro X. low: 10.0, high: 105.0, measured: 43.33
MPU6050: Self test gyro Y. low: -105.0, high: -10.0, measured: -43.88
MPU6050: Self test gyro Z. low: 10.0, high: 105.0, measured: 52.12
MPU6050: Self test acc X. low: 0.30, high: 0.95, measured: 0.61
MPU6050: Self test acc Y. low: 0.30, high: 0.95, measured: 0.51
MPU6050: Self test acc Z. low: 0.30, high: 0.95, measured: 0.58
MPU6050: Self test [OK].

And make sure to have the Crazyflie on a stable surface while powering it on and post the result here.

Good news, your Crazyflie seems perfectly fine. Can you try the latest stable release again, or maybe you already done that?

[KOschi]

You are right. I allready done that after i replaced the motor which was not working AND the Fly is working again. But i have strange disconnects every now and then when flying. Its not even far away from the crazyradio, its like 3-4 meters away.

[tobias]

It can be due to interfering wifi networks. Have a look here.
