Connecting to QGC with ubuntu

[JDiam3]

I'm following the instructions here: https://github.com/intel-aero/meta-intel-aero/wiki/90-(References)-OS-user-Installation 90 (References) OS user Installation · intel-aero/meta-intel-aero Wiki · GitHub to attempt to connect by drone (running ubuntu) to QGC on my laptop:

Get your laptop IP and run on Aero:

• sudo mkdir /etc/mavlink-router/config.d
• create this file: sudo gedit /etc/mavlink-router/config.d/qgc.conf and fill it with:

[UdpEndpoint wifi]  Mode = Normal  Address =

• launch QGroundControl on your laptop. It should receive automatically the telemetry feed from the drone.

Both my drone and laptop are connected to the same wifi network and the qgc.conf file contains the proper IP address of my laptop. However, QGC on my laptop is not connecting to the drone. Any advice for diagnosing this problem?

Hi, Jeffrey95

Thank you for contacting Intel Customer Support. What is the output of the get_aero_version.py command?Also, can you try to disable the firewall on your computer? It might be blocking the connection between QGC and the Aero Drone.Regards,Alexandra

BIOS_VERSION = Aero-01.00.13

OS_VERSION = Ubuntu 16.04.3 LTS"

AIRMAP_VERSION = unkown

FPGA_VERSION = 0xc2

AeroFC firmware version = unknown

There's no firewall on my computer. I had no problems running QGC when I was running yocto on the drone. This problem only occurred when I switched to ubuntu.

I've updated the FC firmware with the wiki instructions (although it took many attempts to do this successfully):

cd /etc/aerofc/px4/

sudo aerofc-update.sh nuttx-aerofc-v1-default.px4

However, even after flashing the PX4 firmware, "sudo aero-get-version.py" still shows an unknown AeroFC firmware version.

I can confirm that I'm booted with the proper ubuntu version: when I run "uname -a" I get "Linux my-drone 4.4.76-aero-1.2 # 1 ... "

Hello Yograj,

Thank you for your reply.I would suggest you re-install the "aero-sytem" package using the instructions on our wiki: https://github.com/intel-aero/meta-intel-aero/wiki/90-(References)-OS-user-Installation or re-install Ubuntu.There seems to be an issue with the mavlink-router configuration and should be working after the fresh install.Hope this helps.Regards,Octavian
