Hello-

I'm Anthony and have been working on a build for the last month now of a quad that will be using LTE. I have been building quads for several years, started from kits to 3d printing my own to CNC from carbon fiber. I have been building these traditionally using the following equipment as example- 2.4 GHz TX/RX, 5.8 GHz or 1.3 GHz vid rx/tx nazav2 or pixhawk for auto. I've been using the 915 MHz modules for telemetry. I own a precision Ag business in the southern United States and fly crop fields nearly every day (weather permitting) and the largest drawback to this equipment is range.

Since I custom build my own frames I can pretty much build it for however long I want it to fly I just can’t keep link with it for the distance I want or if I decide to move to a field on the other side of a wood line from where I’m standing. I bought a PI 3, Navio 2, Logitech c525, a couple of Verizon mobile hotspots (did have dongles) couldn’t get port forwarding to work so I went to Wi-Fi modems... (another story).... anyway, the reason I'm emailing you is because I know you have the knowledge to get your equipment off the ground and going using cellular, I'm totally ignorant on Linux however; I'm learning.

I really need some help to determine how to get the PI to communicate with my pc (running win 10) as my MP GS. I've been fighting for a month over this and can't seem to wrap my head around how to get it going. I've been successful connecting the 2 over the same wireless network but trying to do it over cellular has been a real headache, and I hate wasting money- but, I hate wasting time even more lol. Could you please mentor/guide me through this? I'll be in your debt. Thank you for your time!

I simply setup a vpn conenction from my Pi to the fritzbox, used the MAVproxy (instead of the TTL to to ethernet converter)
and it works well. It is not optimized for latency or performance but i'm using my drone with the python dronekit to make autonomos
missions, so i'm okay with that. Here's how i set up the vpn connection (only works with fritzbox)

sudo apt-get install vpnc
sudo nano /etc/vpnc/fritzbox.conf
    (insert and change to your settings)
    IPSec gateway fritzbox.no-ip.org
    IPSec ID pi
    IPSec secret OvNBulWSsmzwqZ2d
    IKE Authmode psk
    Xauth username rpi
    Xauth password secret
    local port 0

you now have to put

sudo vpnc fritzbox.conf

in the rc.local file after the dronestart command.

Here's how to set up MAVproxy: http://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html

I now wrote myself a python scriptd and soldered a button to my pi's GPIO's and made the button start the MAVproxy with my specific GCS IP

Thx for the info Dane,

Let me see if I got this right maybe someone will correct me if I'm wrong. Ok, my initial plan was to put a wifi connection or connect dongle to the aircraft - login to my vpn from the aircraft. Connect wifi to my pc and login to vpn from pc. I was originally under the impression both devices would talk to the VPN from the outside and act as if both were on the LAN. So far it looks like the pc will have to be on the router lan and the quad will login to the VPN and that's how they establish communication. Is that correct? Or can 2 independent devices on 2 separate connections communicate to the standalone router through vpn and act as if they're on the same lan? If I'm right with the first assumption that the pc will have to stay connected to the router lan, then I've been doing it right from the beginning because, I can get them to work that way... just ridiculous having to be near a router all the time lol.

Thanks for your input!

thegreatdane6

If both devices are connected via vpn to the same router they act like they're in the same network (thats the sense of vpn), you just need to get the local IP they get from the router so you are able to connect.

ADSB_OWNER

Then.... I'm not doing something right lol. I have an ASUS router and setup ddns from no-ip. I register the ddns in the router and can connect to the VPN with the pc and the quad the only thing that will let me communicate with theach quad is putty through ssh.... I can type command lines but if I try to fire the navio up to send Com back to the pc it doesn't receive it the traditional way through udp 14550.... as of right now the only way I can receive those coms is if I connect the pc to the router and boot the pi and have it boot to the vpn... ugh I should have took some school in this it hard for someone ignorant like me lol Thank you for your help

Hello all, I registered just to say how impressed i am with this blog. I grabbed UAVcast image and I have my RasPi2 with Logitech c615 web cam streaming out just fine to VLC. Looks like i'll need a little hardware to get this connected to my pixhawk, one step at a time though. I'm sure i'll have a few questions, hopefully i can answer questions for others.

Thanks for all who contribute to this!

Hi folks, nice image and awesome all-in-one navio-rpi-cell drone package.

I'm using(tested) Huawei 3g E3131s-2 and Huawei lte e3272 which are working well with RPI3 after uqmi setup (just followed the Bernt isntructions). Nevertheless, I have some questions:

1) As I understood in order to get SSH and gstremer connection to the drone from the GSC in outdoor (outside of your local home network) you have to get at least 2 devices which have access to internet for both side (RPI & GSC). Using tele2 mobile provider (Huawei 3g E3131s) on RPI side registered it on the noip dydns services, and name smth like tele2rpitest.ddns.net and the same stuff for GSC (using Huawei lte e3272) and name it smth like altelrpi.ddns.net, and I can't make a SSH connection between it. I've tried using putty (and linux terminal as well) entering tele2rpitest.ddns.net port 22 and push the Connect button (there is no any feedback, just stuckin for a while and got timeout error ). Am I doing smth wrong?

2) for 1st question I've some idea about port forwarding. And may be it's need make some setting on the routers, BUT when I'm entering the (192.168.0.1 router's web interface) there are no any "options" where I can setup VPN, port forwarding, etc...

So I searched and faced up with weaved service which doing port forwarding and other stuff like a SSH, TCP, etc.. service working well on raspberry pi remotely, without any port forwarding headache. It works fine, but it's seems to me too much laggy about 3 at least and 8 seconds at most for waiting and typing the next command on the terminal via SSH. (actually I can't say so, because I cant estimate it and compare with normal process like if I have some possibilitie for right port forwaring settings on my usb 3g modem). At least I can connect to my Raspberry pi which flying around from any places where exist mobile cell coverage.

But, I'm still stuck in how get link between RPI and GSC, please any help will appreciate.

Hi all that works rasp3 with emlid rt kernel image ?

That is way better than a TTL adapter. Good info!

have you tried to set your AP to "internet.public " ?

I am trying to install in Navio2.
I am loading the img on navio website onto the sd card and from there installing UAVcast.
about 50 min into the installation I get multiple "segmentation fault"errors as this one:

 Selecting previously unselected package usb-modeswitch.
Preparing to unpack .../usb-modeswitch_2.2.0+repack0-2_armhf.deb ...
Unpacking usb-modeswitch (2.2.0+repack0-2) ...
Processing triggers for initramfs-tools (0.120+deb8u1) ...
Segmentation fault
dpkg: error processing package initramfs-tools (--unpack):
subprocess installed post-installation script returned error exit status 139

What can I do to get it installed? If I install you img directly onto the sd card i get an error when trying to run ArduPilot something about "i2c device"

Hi Daniel. Try to run a apt-get update and verify that your package list get successfully updated.

Hi Christian,

I am a French student and I’m trying to implement your system to have a long range telemetry and feedback video. But I’m wondering why do you use the Raspberry’s Ethernet port for telemetry instead of the serial link? We could wire the Pixhawk’s telemetry port directly to the rpi’s serial link (as shown below) with a PPP protocol? In this way, we wouldn’t need to use a converter?

Hi Martin

I was never able to get the UDP working by simply connect the serial directly to the Raspberry GPIO, that’s why i used the TTL to Eth converter. I did manage to get MavProxy running at UDP this way, but mavproxy uses allot of the raspberry CPU, so i decided to skip it.

You are welcome to provide any other solution to make this system become more convenience to use. Im sure there are other ways.

Martin_Vigneau

Hi Christian,

Thank you so much for you quick response.
I'm a beginner in these skills so I guess if you were not able to get the UDP working, I won't !

I would have another question : Is the telemetry link bidirectional? Because the function udp_redirect () seems to redirect data from the ethernet port to the internet but what about the other way ?

Thank you Christian for your help

Hi
Yes the telemetry is bidirectional. It works exactly the same way as any other radio link. 🙂

Ok Thanks Christian !
