Problems with px4 optical Flow

Good afternoon,

I send you this mail to ask for help on the configuration of my Px4flow optical. I followed step by step the tutorial of

And after installing the firmware px4flow-klt-06Dec2014 and calibrating the lens by usb with the mission planer, I can not receive data by i2C. I connect the px4 flow through I2C to the pixhakw and select Optical flow enable (1) and do not get data to the op status of the mission planer.

Please help me if there is any data to configure.
