    Hi Thomas,

    I'm like you, in the dark for setting up my PX4flow.

    By testing a lot of things, i finally have a good signal, correlated with Imu signal.

    The sonar seems to not be compatible with pixhawk/apmcopter, and i try to solder another one instead. I will let you know if I achieve something.

    Important issue is that Px4flow does not initialise if powered by the main battery first. You have to power your pixhawk with USB, then connect the main battery and unplug the usb.

    Where are you with your set up? Is it working? Did you gind a place with discussion about it?

    Julien
