QGroundControl no connection


#1

Good evening,

Greetings all, I am looking for some guidance and help. I would be most appreciative for any input! Before plucking down $ for the bluerov, I am trying to setup a benchtop rov (Raspbery Pi and pixhawk, neither of which I ever used, no housings, no motors, etc) for protyping purposes.

I am having trouble connecting via qgroundcontrol and recieving the message “Waiting for vehicle to connect”

Some details for trouble shooting…(sorry if this is information overload)

-Topside computer running windows 10 and QGroundControl v3.2.4 BlueRobotics Rev 6
-Raspberry Pi 3 B with updated Rasbian installed (i also have a 3B + …oops).
-Purchased Pixhawk from mRobotics (I hope this is the correct version) (no camera yet)

-I was able to flash the firmware on the Pixhawk by connecting the laptop to pixhawk via usb cable. Firmware Version 3.5.3, Git Revision ad81760b, Frame Type: Vectored/BlueROV2 (I have not yet completed compass and accelerometer setup, however QGroundControl compass and pitch info is responsive when the Pixhawk is connected to laptop via usb)

-laptop and raspberry Pi are connected via ethernet cables to a small hub
-turned off wifi on both topside computer and Pi
-Topside computer has static ip address 192.168.2.1 (255.255.255.0 subnet mask)
-Pi has static ip address 192.168.2.2 (255.255.255.0 subnet mask)
-I can ping Pi from laptop
-I have installed mavlink and mavproxy as well (do these load automatically at bootup?)
-Pi is powered with ac adapter via mini-usb connector
-I have tried connecting and powering the Pixhawk to Pi via usb and also per wiring diagram on the ardupilot website… no luck.

Hi @pdj, glad you found us!

Please check ardusub.com for setup instructions. Specifically, you will need to download/burn our own image for the raspberry pi sd card so that everything will work ‘out of the box’.
