Connect a Raspberry Pi to a Pixhawk running Ardupilot/PX4
HTML-код
- Опубликовано: 20 авг 2024
- We setup a Raspberry Pi 3 to be working as a companion PC for your autopilot, running Ardupilot/PX4.
My personal advise is not to use APM 2.x board. You need a 32 bit autopilot to get the best off Ardupilot. Find a few links below.

Is it possible to connect to the onboard Rasberry pi with rfd 900 telemetry or herelink telemetry? If so, can you make a video on how to set it up ? The short WiFi range for Rasberry pi communication is a big limitation and 4g is unreliable where I live. Thanks
Hi, Tiziano. Thank you for making these tutorials. I learnt how to program drones using your video and made an agricultural drone prototype for which I won a contest in college. Please upload more drone videos in the future:)
Great to hear! Never stop learning and be passionate, post your experiments tests and fails
In the video I forgot to DISABLE THE BLUETOOTH. Open the file /boot/config.txt and add the following line: dtoverlay=pi3-disable-bt
Based on the audio, I believe this is Darth Vader's younger geeky italian brother
Thanks from turkey. Grazie mille Tiziano, da un turco-italiano. Sei il migliore.
Sir you are truly a great teacher. Hats off. I haven't seen any teacher be such great at teaching complex mechanisms like you have. Thanks a ton
Thanks, your feedback is what makes me doing that
Perfect timing ! I have 10 days to make this happen .
Glad it was helpful
It's actually the project I'm working on ! Raspberrypi to Pixhawk on a HMF U580 quadcopter perfect for my project .
How did you go? did you get it going? and are you using 3/4g or just as an inboard companion?
@@noahorosw How did it go ? Same for me but with a Jetson nano instead of the pi.
I didn't add any system like that, but you can use a maverick image for that purpose. In my case I just set the host name up with a unique name (i.e. raspi-uav) so then I can refer to the host name as name.local (i.e. raspi-uav.local) rather than warring about fundung the ip address
Just a tip for all of you doing this project ! The pixhawk telemetry port 2 will not power the raspberrypi . You will have to solder power outlet wires from the main board , and connect a ubec to power the pi . Then you can ssh wireless to windows pc . Otherwise no connection .
At least for me the pi was just constantly rebooting , never actually starting . I hdmi a monitor to pi to find this .
Definitely install the ubec ! After finally loading Ubuntu Mate , the power cord that was supplied with the pi wasn't enough to power it ...
Hello! Did you get it working using RPi GPIO UART connected to UART telemetry port of the flight controller?
Hello
I powered my rpi3b via the telemetry 2 port and it runs perfectly, the thing you said got me in a glitch as the setup is perfect running.
@@PankajMali Hi bro, did you use the UBEC?
For next video, object tracking using opencv as you said (or) tracking mobile GPS as my suggestion. Great Video! Thanks
Sundaresan .N it probably won't be the next, but definitely a must do. Thanks
I did it ! I got it to connect with test_connect.py at 57600 baudrate on the modified file ... COOL !!!!
Now that wasn't hard at all ...
I'm blown away ! Totally amazing .
Thank you very much but please slow down a little :-)
I just want to say one more thing . You're awesome for doing all of this , for all of us . Weather we figure it out or not ? We should have to pay for this type of education you give away for free ... Thank you
Thanks Noah, that means a lot to me
Tiziano Fiorenzani did you get a chance to look at the connection logs ?
It looks like you are trying to connect with SS0. That is not possible. You need to stick with AMA0, but check the updated description for a missing part of the video
Tiziano Fiorenzani Okay I will soon as I get home
Okay I got it ... I can take it from here ... I will always follow your videos , and continue to build awesome QuadCopters .
brother your teaching style is very good --Thank u . brother i have a problem that Mode change not work in dronekit ! no response in pychon3 but python 2.7 work properly . how i fix it??
Hey Great Work. Can you make a video with a Jetson nano connected to the Pixhawk ?
Do you find anything?
many thanks for a very helpful video
Sure, I am glad it did help you
Hello sir, now i am working on a autonomous UAV fixed-wing project. I was happy and pleasured to see your working. Thank for that. I have an issue that when i tried to install samba i am having problems as temporary faliure resolving 'raspbian.raspberrypi.org'. I searched for solution but couldnt find helpful one. Hopethat you will help me about that.
Have a nice day
Samba is just a tool for helping you sharing content. You could also use an ftp server (Like the one already included in MobaxTerm), or git
Hi, Tiziano. Thanks for the tutorial, it's an excellent work. I have a question also: I have a raspberry pi which is to run a Dronekit-based object detection program; How can i access to my raspberry pi over the Mission Planner to get the object detection program started before the drone takes off?
Connect through wifi and build a simple user interface in python for example. Send UDP messages to command your raspberry pi
Simply amazing, grazie!
can you show us how to run any Python script on RPi and see the simulation on mission planner ? A small video this would be very helpful, thank you in advance
to ssh into raspberry pi 3 just take the ssd card, install ubuntu on it, then go to the roots folder and create a folder called ssh
then get your ip scanner of choice, connect the raspberry via LAN and scan for your pi
everything else is common, go to terminal, ssh pi@ip and your in like flinn with raspberry as password
Course you can, but when you have multiple boards connected, the easiest way to me is to give each of them a different host name and then connect with name.local, rather that sniffing their ip every time
Great, thanks. i am anxious to learn more about the capabilities of a companion pc. Are you going to be making more videos about writing your own scripts. can you point me to some good resourcers on this topic.
hello i have been following your tutorial for some time and i was able to this raspberry Pi and Pixhawk connection successfully and now i have to use a different controller the cuav v5++ but i tried the same way as the Pixhawk but it's not able to send data i will be happy if you could assist because it is for my 2nd year project i will be happy to share the progress of the new drone with you if you are interested
Thank you
Hi i did all the steps following the video and even disable rpi 3 bluetooth, however i got an error which state serial.serialutil.SerialException: [Errno 2] could not open port /dev/ttACM0: [Errno 2] No such file or directory: '/dev/ttACM0'
Ok, by default ACM0 is given to the bluetooth. Check again that step. Otherwise you can use the default port, should be ttyS0 (?). You can check with ls /dev/tty*
hi Tiziano, Thanks for this awesome tutorial video, I have one question, is the procedure explained in the video same for CC3D flight controller also ?
As long as is Mavlink and runs Ardupilot it should be ok

Sir, can we connect pixhawk 2.4.8 with raspberry Pi and install drone kit?
Awesome video .
how the (public?) IP address is managed? Is there an AWS-like service to connect and reach the drone "node" when we go connected?
For those of you who are trying this on ardusub companion software
-username:pi
-password:companion
You will thank me later :)
It qould be amazing to controll the drone with 3g network. Nice video btw
It actually is. For example check this video: ruclips.net/video/iUctV-tqh_M/видео.html or even this example with a Navio2 (basically a Raspberry Pi on steroids) diydrones.com/profiles/blogs/navio-awsome-flight-controller-from-emlid-tested-with-4g-cellular
Yeah that's exactly what I am currently working on.
I use a Huawei 4G LTE USB modem with a Sim inside.
I created a crontab entry that automatically connects to an openvpn Network after system boot.
This way the drone is reachable over the internet from any GCS that is connected to the same OVPN network.
Additionally mavlink-router service must be installed, configured and running in background so that the telemetry traffic is
routed from udp socket to the serial port and back.
It takes a bit of work but once it runs stable it is indeed very powerful. The remote control range over mavlink of your drone is now unlimited as long as mobile reception is available.
Sir can you please guide me about how do i connect apm 2.8 with raspberry using usb..... I tried connecting it using uart but failed miserably now not even connecting to mission planner..... Please help sir
Do not use 8bit boards
I noticed that at the start of this video you you listed the Intel Edison as an option. That seems, to me a better option, so can you do a video on that setup? Or tell us how to use this instead?
Intel recently dropped the whole Edison project, in case you haven't heard already.
I can not installing samba to raspberry pi 4 . There is many errors occurs. can u help
I don't understand why. In my case, you can Use MobaxTerm for ssh and SFTP all in one tool
Dear sir, fantastic vídeo!
Can se aplly thís to a homnibus f4 or f3 series flight controles boards?
As long as you flash Arducopter on it
earlier in the video it shows connection by serial to the raspberry pi. later it shows connection via micro usb. which one should we use?
For a quick debug you can use the USB. I'd recommend the serial port for your application, as sometimes the USB could trigger some debugging mode you don't want during the flight.
What about connection of Pixhawk and Jetson Nano?
It works the same way
Hi.
I am very interested in this tutorial, but I don't know if you already updated the repositories of how_do_drones_work.
Could you do a new tutorial?
Good evening

Hello,
I'm using pixhawk flight controller. The problem is with banking angle which was shown in the flight data screen. When I roll the flight controller to left, it's banking to right and vice versa. Can you help me out to solve this problem?pls help
it looks like you mounted the autopilot backward or the parameter AHRS_ORIENTATION is not correct
Perhaps we can do a python script to display osd information ?
Yes. Try it out!
Very interesting ! it's just what i'm trying to make!
If I would like to buy a new drone (or make myself...) with pixhawk connectable to Rpi3 the way you show, where can I try ?
marcoHammond check out the Ardupilot.org or px4.io website, in their companion pc page. You can find even other all in one solutions
I am getting this error even after ensuring that all the above steps are correctly done. Please help !

Yep
I am using pixhawk 4 and a Raspberry pi 4 and connected them in serial through telem2 port on pixhawk 4. So I am using /dev/ttyAMA0 with baud rate fixed at 921600 (following ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html) but I have no heartbeat. Can you help me when I run test_connect.py
if you used pixhawk before, you should delete all files into pixhawk sd card.
thank you sir, will this work for fixed wings too?
Yes, I have a video and a library that I developed just for fixed wing
@@prandtlmayerthank you for replying 😊.. yes sir i have watched it . its only about simulation will it work real models?
I have an APM 2.8, If I connect the RPI on the telem port, then where will I connect the telemetry module used for connecting to the ground station through the Mission planner? There is only one TELEM port. Is there any way I could use both with APM?
Apm is not a good choice. Use any 32 bit board
Thanks for the great tutorial Tiziano, something I was looking for.
I have a little and strange problem though.
I am not able to connect over USB (ttyACM0), connection times out. I do see ttyACM0 appear and disappear (ls /dev/tty*) as I plug and unplug USB cable but the following python script keeps on failing
>> vehicle = connect ("/dev/ttyACM0", baud="115200", wait_ready=True)
Lost me at configuring smb.conf and cannot discover pi on network.
Solution: For those of you that have a similar problem - go to Control Panel>Programs and Features>"Turn Windows features on or off" (left panel)>check "SMB 1.0/CIFS File Sharing Support"> reboot.

Can you connect the telem2 of the pix hawk to giout tx and rx pin of the raspi if you have a 4ghat on the raspi already?
As long as those pins are unused, yes. You can also use a USB connection
@@prandtlmayer how can you check they are not used ? I could not find any video explaining the commands to change to have it connected to usb of raspi.
plz tel me one thing how i can find coordinates while ardu connected with GPS and we take image from picamera ?????
Once connected, use the vehicle.location field
Hello, excellent video really helpful.
I have a question, I'm looking into adding a linux computer to my projects but I am still not sure wether is better to add a Raspberry pi to a pixhawk controller or if I should go with a controller that alredy has the computer inside of it like the Beagle Bone Blue, what would you recommend?
If this is your first built I'd say keep things separated, a microcontroller based flight computer and a Linux companion PC.
Tiziano Fiorenzani thank you. Do you have a recommendation on which pixhawk to buy?
I am getting this error in the throttle part any reason why ?

KeyError: 'THR_MIN'
Since the time of the video, they changed the name of the parameter
@@prandtlmayer is there a new name, also I have been researching, does it support pixhawk 4 ?
Great video. One question. I want to run dronekit python code from Raspberry Pi while connected to Pixhawk. And I want to see the process from mission planner which is connected with Piaxhawk with telemetry radios. When I tried it, it says mode 0 not available on mavlink definition. Don't know how to solve. Thank you
최정훈 stick with the tutorial. Have you followed step by step?
It would be helpful if you explained what and why you were doing things instead of just telling the steps... I do know how to set it up but I have no clue why you changed the memory to 1024 and what’s X11 tunneling is
If you watch the other videos of the playlist they might answer you why I am setting up a companion PC. In this video I just show how. The swap memory is jist the virtual memory, that is a little small but default.
@@prandtlmayer Thank you for your answer, indeed it helped.
Would it be possible to connect a raspberry Pi to other flight controllers like the Mamba F405 directly with a raspberry pi? I am trying to do so using serial or PPM or SBUS but cannot find out how. It seems like the raspberry pi must act like a radio-controller. Would I need to use Betaflight or something else?
As long as you know the protocol, you can connect with whatever you want. The very least interface level is using Servoblaster for controlling Gpios as servo and interface to the board as a radio receiver
Sir, is it possible to connect the Raspberry Pi 3 to the Pixhawk via the USB ports on both devices (instead of connecting the GPIO pins to the Telem port) ? I am trying to connect a Raspberry Pi to the Pixhawk Cube on the 3DR solo mainboard to implement a autonomous object tracking function.
It's possible even though is not recommended. The autopilot might think it's in debug mode. Check it out on the Ardupilot forum
Is dronkit supported raspberry pi 4 + rasbian buster sir ?
Can I install win10iot core for rasp pi 3, (I will plug a small stick 4g modem I hope drivers will work on win10 core). And then install mission planner windows version to rasperry pi 3 and control the pix hawk 4 via bluetooth or wired connection?
I don't know, but it's worth trying
very greatful Thankyou for the push, got everything to get going just 1 question. Do you need both drone kit and Mavlink on the RPi. In the documentation it says you can load dronekit if you want to do tracking and add other features but is not clear if it is required to run just mavlink over 3/4g? If all you want is to control the drone not have video tracking and such, also it states that most of dronekit is in the mavlink API.
After your little push I have done a lottttttt of reading and taken the huge learning curve as you suggested and followed your advice and I am very grateful that you pushed me to do that. Your right it is much more fun to do it yourself, I just didn't think I had the time so thanks for pushing me off my lazy Butt.
Also did you every get around to do a dronekit Fixed wing/Plane setup? You mentioned that you had been working on such a video. I have not been able to find your video if so, so if you have could you please link it.
Thank you again really appreciate it Gus
I am just collaborating with the local College for a paper about Fixed Wing and Obstacle Avoidance. I am developing the libraries and the SITL. So I will probably come out with a video about it soon.
As for your question, Mavlink is just a protocol, dronekit is sort of a wrapper around the library pymavlink. It makes things much easier for you to handle a vehicle through mavlink interface, creating the object vehicle with lots of properties and methods and giving you the chance of creating your own messages and reading other messages using listeners. You can run dronekit on the companion pc as well as on the ground: it does not matter, as long as you specify the connection port.
I have been using mavlink-router a lot to share the connection with the system to all the other nodes running on the same network. It's sort of mavproxy but lighter weight
Tiziano Fiorenzani so on your github repository would the mavlink api's work for a plane? Also just so you know after some reashearch all I want to do is be able to control my plane over3/4g with mavlink. Mavlink would give me the ability to actually do really long controled flights with a joypad or stick over mission planner GCS. I will obviously want to go further as I get into it but as for now its so I can switch to cruise mode then take over with FBWA and simple controls. Not image recognition or avoidance at the moment. Although that would be a fantastic thing for a plane but would need better than hobby grade sensors.
If you could let me know if you feel that simple control through a GCS with just mavlink is achievable such as some of the videos on youtube of people just using gamepads to fly 15km it would be great.
O and thank you not only have you made me study up on drone stuff I am making a RPi magic mirror for a family member with dementia to help them and integrating it with google home to try and make their life a little easier and it was your comment 'what fun would that be when I ask if I could just buy a RPi setup for flight so you have help in many ways, I am very greatful.
Studying is the key. Never give up on studying, never feel lazy. Nothing is worse than laziness for an engineer. I had done that mistake in the past, never again.
Anyway, I just setup a very nice python library for controlling a plane and I will be releasing the first issue with a video. It won't be long. You can arm and takeoff as a copter, control altitude and heading angle... very nice to expand.
Tiziano Fiorenzani looking forward to it. Am subscribed so look forward to a notice about the video.
After executing the test code I get back the following error:
pi@raspberrypi:~/Rover $ python2 Test.py
>>>> Connecting with the Rover
Probably you haven't set the connection properly. Check the connection and the serial ports baudrate are set the same
Can you do a video how to setup Ardupilot with a cellular radio control link?
That is something I should learn myself first
David Kaden have a look at ANDRUAV. There are not many videos which I hope to rectify but it works straight out of the box with a phone one drone conected to pix and phone as GCS. I use it and works really well.
I am trying to muddle my way through getting a RPI setup going then will swap over and see if any better than ANDRUAV. Free download only works on android. O and its free.

@@prandtlmayer great ! Thank you for your reply😁
First of all, thank you for your time on providing usefull tips for us.
I'm really trying to do this connection using the FC telemetry port and RPi3 UART, but without success. My python code using dronekit works well using NanoPi NEO Air companion computer, but not using RPi3B+. I tried with RPi4B too, nut without success. I followed a lot of tutorials to config the UART ports in Raspberry Pi, but none of them made the thing works. Some data is arriving at /dev/ttyAMA0 according to minicom, but dronekit cannot stablish connection. Could you please give me any help with this? Thanks in advance!
Probably you have still AMA0 assigned to Bluetooth. Check ttyS0
Tiziano Fiorenzani, it was the ground cable. I forgot it was mandatory to close the circuit with the UARTs. Thanks a lot for your time.

Hi everybody. Does Ardusub support to connect pixhawk 2.4.8 with pi 3 model B ?
Are you using a 32bit board?
@@prandtlmayer yes. Pixhawk is a 32 bit board. ArduSub firmware is provided for many of these platforms, but only the Pixhawk 1 is fully tested and supported. So i just want to know there is someone test pixhawk 2.4.8 with ardusub
Bro can you tell how to install latest firmware on pixhawk of arducopter 3.4
Well, bro, 3.4 is probably a two year old version. In any case, you can use any Control station software you like, like Mission Planner. Follow the wiki on ardupilot.org
I am a little new at this and I am trying to build a Drone capable of autonomous flight. what can we do with connecting a raspberry pie? could send and receive data wirelessly (using Bluetooth or something else) ? and also could you connect a raspberry pie in a similar fashion to a audupilot? Thanks a lot :)
Anshul Arora but this series is about that. I think you need first to step back and study deeper Ardupilot on Ardupilot.org, go through the wiki and then you can think of doing more advanced things
is there any reason why we use the lite version of raspbian ?
You don't need a lot of the included software

Great video, sir. I am getting an error that /dev/ttyACM0 doesn't exist (can't open the port ttyACM0) Can you help me, please?
type ls /dev/tty* and check what ports you have. If you plug the autopilot with a USB cable (not recommended for real flight, use the UART instead), the port is usually ttyACM0 unless there is something else on that port or the port is still appended to the previous session. It will then assign ttyACM1 or ttyACM2.... If you use the UART, the predefined port on the Pi3 is ttyS0 or ttyAMA0 if you have disabled the bluetooth (as stated in the description)
Can i use pixracer along raspberry pi?
Is there any difference between pixhawk and pixracer and pixhawk mini?
arpit srivastava course you can. Any autopilot running ardupilot will do
ciao tiziano!video fantastico! tutto questo serve per avere una connessione remota dal drone al pc? ma é una connessione 4g ?spero di essermi fatto capire! grazie in anticipo!
Il tipo di connessione e' indipendente. Puoi connetterti con il companion pc tramite il wifi (che per quanto mi riguarda e' la cosa che faccio solitamente). Puoi certamente connettere un modem 4G all Raspberry e connetterti ad internet. Questo e' ottimo se vuoi gestire il tuo sistema da remoto, molto remoto.
La Pi3 ha il wifi built in, e con un access point di buona fattura puoi avere un range di alcune centinaia di metri

Sorry I was talking about using dronekit-sitl. It turns out the AWS instance that holds the plane image was down. I followed these instructions and in addition I configured USB as eth so that I can sh direct over USB by using this guide www.thepolyglotdeveloper.com/2016/06/connect-raspberry-pi-zero-usb-cable-ssh/
I personally don't use dronekit-sitl anymore, only if you want to test basic control, but the version of the firmware is outdated. If you run on Linux machine (not raspbian), you can run the ardupilot sitl with sim_vehicle.py. In windows you can do the same (even though it's a little bit more involved) or you can use Mission Planner and let it download the latest master rerlease and simulate it. I have a video about this
i am running a sub rov and its set up using Raspi3 with a holybro Pix4. the Pix4 died on me and was given a a radiolink pixhawk4. Looks the same but it would not connect to the RSPi. So i updated the Pix4 with a pix4 firmware and still nothing. I am new to this and so been searching all over the net for 3 days for a solution. any suggestion? Thank you.
What firmware are you running
@@prandtlmayer good news i manage to get the sub rov to work. I use the Qground control. Discovered i had lost power to the dc distribution system because of a faulty hobbywing ESC. Got that changed out bit now my sub's thruster will only turn in one direction. I swapped the thruster with a brand new unit but still the same result. Tried to swap channel on the Pixhawk but the results are the same. The ESC is the identical make and model as the faulty unit. Maybe it needs to be setup as its a new esc? Any advise?
do this steps apply to the raspberry pi zero? I want to set it up as a companion pc and write python scipts and maybe opencv.
luis hernandez i setup the pi zero in the same way. Works nice, but not as powerful as the 3
Hi tiziano can you please provide the details for the file, as i think you have removed or edited the python file dronekit_test_03.py
its renamed but still file 3 so just use that
more tutorials!
Any updates?

Is there other board can be connected with raspberry pie
Every autopilot compatible with Mavlink in general. For dronekit, better Ardupilot
4:49 - shouldn't it be "browsable' instead of 'browesable'?
Actually is "browseable" : www.samba.org/samba/docs/current/man-html/smb.conf.5.html
Can I use Raspberry Pi 4 with Pixhawk
Anything will work, any Linux or windows board
Is there a way to connect pixhawk 2.1 to raspberry pi?
Same way. Through the telemetry port
4:59 We can't access to scripts folder before enter our password. Eventhough we write the password correctly we can't open the pidrone and access to scripts. The error is "Access is denied".
It says we don't have permission to access to the RASPBERRYPI network
Verify you have followed all of the steps for setting up the board. You can also switch to "Mobaxterm" that includes an ftp server with drag and drop, so you can skip samba completely
@@prandtlmayer Thanks a lot for your answer, we opened file on PuTTy and made changes in it but we ended up with an error:
Traceback (most recent call last):
File "test_connect.py", line 80, in
print("Maximum Throttle: %d"%vehicle.parameters['THR_MIN'])
File "build/bdist.linux-armv7l/egg/dronekit/__init__.py", line 2714, in getitem
KeyError: 'THR_MIN'
We couldn't understand the error and we don't have much time. Can you tell what's wrong?
@@prandtlmayer We suppose 'THR_MIN' is no longer available as a parameter, what should we use instead of 'THR_MIN' ? Will 'THR_PASS_STAB' work?
Hello. the same problem happened with me. how did you solve the problem.
Hello,
Hope all is well. Just a quick question on your companion computer (RPi) interface. How's the reliability with connection between micro USB port on Pixhawk to USB A port on RPi? Will it be reliable enough for running control loops on RPi while flying?
Thank you in advance,
AK
Reliability is good, but I would not go that way. Use the serial port instead. You can go as fast as 1Mbps and does not have all of the hurdle and fragility of USB
@@prandtlmayer Thank you for your input! Will set up to use serial port instead of USB.
Hi. I am new to RP. Does all the programs work with RP 4 version? Thanks.
Every single board computer running a Linux distribution would work. Some are better than others, but the raspberry Pi covers most of your projects and has a good support from the community
Hi Tiziano, great video, how can I chose my flight controller? I'm seeking a more cheaper FC instead of Pixhawk that can run with raspberry pi + px4/ardupilot.. Because I'm in a project that will involve multiple autopiloting drones with flightpaths. Thank you.
There are many flavors and I do have my favorites. As for you, it depends on your budget. If you are setting up a cheap system, go with any 32 bit "pixhawk" clone (hobbyking, holybro, rctimer...) They will work fine, run Ardupilot or PX4 and they connect to any companion. If you need smaller boards, there is the pixfalcon and similar you can check out. The difference is that the smaller boards usually have only one IMU. Otherwise you can lean towards a RaspberyyPi hat type, like the Navio
@@prandtlmayer Thank you very much.
Sorry to bother you again Tiziano.
Ciao, I will go for pixhawk or navio2 like you suggest, my project involves gps missions with the support of ardupilot or maybe px4. I've seek info about the pros and cons of both flight controllers but it seems that there isn't a reliable reviews about witch one chose. Seems like Navio2 has a better gps tracker (?).
Any suggestions? And thank you again.
Regards from Verona, Italy.
I can't wait till the Edison video ! I love Intel processors ...
It's just a matter of ! "Focus on the added value " .
Is there a need to install MAVProxy for this?
You don't need to. You are ok with the SITL already. Mavproxy is a great tool to know though, very useful if, for example, you want to share your one connection with multiple computers, phone apps...
