Connection between navio2 and dronekit

[chiritagabriela]

Hello everyone,

I am a newbie in working with navio2 and i want to do a personal project on a quadcopter. But i am having a hard time understanding how i could run a script on the board. I looked into dronekit and the python programmes found there and i tried to connect via mavlink. But all the tutorials i followed did not work, because it always gives connection timeout.

Could anyone, please, explain to me how can i run a script on navio2 and also see the result in Mission Planner?

Hi @chiritagabriela,

Thanks for your patience!

Could you please specify if you’re working with the latest image? There, we’ve improved the connection to Dronekit.

Also, it’d be great if you could share the screenshot of the error with us.

Hi @polina.buriak,

Thank you very much for the response.
First of all, i have a question regarding the workflow.
So, basically, what i have to do is to go into my raspberry pi via ssh, and run:
mavproxy.py --master:udp:pi_ip --out udp:pi_ip:14550 --out udp:pi_ip:14551
then go to my laptop and try to run, for example, python vehicle_state.py --connect udp:pi_ip:14551?
and mission planner should connect to udp:pi_ip:14550
Also, for being able to run mavrproxy, do i need a telemetry module plugged in the UART slot?
note that both laptop and rpi are connected to the same network
And if i do all of these above, this is what i get(even though the firewall is off: connection refused, no hearthbeat.

Sorry for asking so many questions, but i am dealing with this problem for over a month and i really need to get this fixed in order to move on with the project. Even though i searched all the Internet, it seems that everything i try to do, does not work.
Aaand, yes, the image is updated.
Thank you very much!

Can't connect to UART telemetry , receiving garbage on putty

Hello, n00b here! I am trying to connect my windows 10 laptop to my drone via 3dr telemetry modules. I successfully connected Mission Planner but I also want to have connection to the RPi terminal via Putty. I set putty to serial and 57600 baud rate as MP has it, but I am receiving garbage. Can anyone help me please?

Navio2 + Pi4 (Copter), Mission Planner SITL

Hello all, Hardware: Pi 4 8GB Navio 2 I am currently working on an autonomous drone for school. I currently have my Navio2 mounted on my pi. I am able to connect to my Navio/Pi through udp and I am able to see GPS, and IMU data sent to Mission planner on my windows machine. I was able to get SITL to run on my Linux machine (separate device) and run a basic mission with QCGroundControl. My question is am I able to do something similar where I can test the Navio using SITL/HITL? Will this…

Hope this is of some help.

Hi @chiritagabriela,

We have a brief guide on how to connect to your GCS via mavproxy. You can find it here. Generally, you will need to use the following command for connection:

mavproxy.py --master 127.0.0.1:14550 --out GCS_IP:14500

To learn more about working with Dronekit, you can use their detailed wiki. For running the example, I suppose you would need to change the IP address for loop one, like this:

python vehicle_state.py --connect udpin:127.0.0.1:14550

I’d also suggest checking out the threads Karl shared. They might help you with general understanding a bit more.
