Data Output from PX4Flow camera board

[rushilkhurana]

I am having trouble getting output from the PX4Flow camera board.

When I use the MAVlink inspector in QGroundControl and I am able to very minor changes in the optical flow values when I shake my hand vigorously in front of it (not enough I think). The camera feed/visualization seems okay.

However, if I try to read any values using existing APIs such as PyPX4Flow, I am not able to get any values. It prints out "Fail" which according to the code means that there was no value obtained for ground_distance. I looked at the mavlink parser that the library implemented, and it seems okay- but I might be wrong there.

The arduino-i2c doesn't seem to work anymore. The library errors out.

I am trying to use PX4Flow board as an optical flow sensor in my personal projects, and I was wondering if I could get some help in how to obtain the computed flow values.

Firmware version: v1. (v2 firmware doesn't seem to work with the board I have).
