Unreliable barometric altitude (Arduplane 2.30)

Just got into this about 2 weeks ago, and really enjoyed it.

It is so much fun! :)

 

But today I experienced this pitch down and dive hard unexpected movements that my plane made.

I took off 3 more times, everything seamed ok, in the begining, but suddenly it happened again, and again. Luckily i did not crash.

 

Then it was time to check the logs. And i saw this. 6000m???!!!

 

Have you experienced such a thing?

 

 

 

 Please help.

At this point, i can not trust my APM anymore.

And it does feel bad. :(

I've just pushed out ArduPlane 2.31 to fix this bug. Thanks to Randy for the fix!

Cheers, Tridge

Did someone had problems with your APM1 barometric sensor BMP085? My one is providing a strange measure of 116353 for the GND_ABS_PRESS and 2200 deg for temperature. To check this I used the barometer test code at ArduPlane2.34\libraries\AP_Baro\examples\AP_Baro_BMP085_test\AP_Baro_BMP085_test.pde
the value of 116353 is higher than 101325.0 producing a number higher than 1 in the calculation.
I tested it byusing the APM Planner test option airpressure that shows the same value for GND_ABS_PRESS and 220 for the temperature.

Hi,

I replaced the IMU board to other I have and the readings are then 91754 for GND_ABS_PRESS and 20 deg for temperature. So with this other IMU it is workin ok as showed by the test program as well by the Planner test option and HUD.

To my APM to work with that IMU having this faulty sensor I replaced de mix from 0 to 1 to use GPS only for altitude.

It is common to this BMP085 sensor to be faulty? Did someone have similar problem?

regards,
Omar
