Hi ArduPilot community,
I'm trying to install a px4flow sensor on my quad and I've been following the setup guide by ardupilot (http://ardupilot.org/copter/docs/common-px4flow-overview.html)
I uploaded the firmware using QGC and focused the lense without any problems, but when I got to the step of testing the sensor, my measurements are far from the ones shown in the guide.
Here are my OF.flowX and OF.flowY readings:

The output spikes seem random and the spike values are a couple of hundred times higher than what is expected. The spikes however only appear when I really move the sensor. If I don't move the sensor, there are no spikes, which means that those spikes are a reaction of he sensor and not totally arbitrary. Similar with OF.bodyX and OF.bodyY:

Here, the spikes are in the domains of a couple of thousands, which is insane.My gyroscopic readings are pretty credible in comparison to that:

Clik here to view.I'm running APM Copter V3.4-dev on an Erle Brain 2.
I was using MP 1.3.44 to take the screenshots but I get similar results with QGC or APM Planner.I also tested the px4flow with an arduino to see if the sensor was broken but the readings were good and it working fine.
If anyone has any ideas how I could maybe fix this, please let me know! I've been stuck with this problem for a pretty long time. Thanks!
