Telemetry over cellular IP

Develop standard, re-usable inexpensive solutions for IP-enabled always-on UAVs over cellular IP networks such as GPRS, 3G, 4G etc.

Primary goal: Telemetry over low cost cellular [achieved in testing]

Secondary goal: Bi-directional GCS/Telemetry over cellular IP [achieved in testing]

Tertiary goal: High speed IP for streaming IP video over cellular 3G/4G

STATUS: Bi-directional telemetry over cellular IP (UDP or TCP) is now working. It has been flown successfully while logging live telemetry to a GCS at home, several miles away [distance is really unlimited]. Currently working on improving code, more testing and broader hardware support.

Hey Guys,

Quick update, I got it to connect and start getting the params, but now it freezes on one and stops loading. "One" being random once "GPS_GLITCH", once "STB_YAW_P", and a host of others. Please help. Also, I've attached another version of the code here:

Hey guys,

I'm trying to implement telemetry over GPRS on my X350 Pro, so I'm using an Arduino Uno to do the configuration as per your instructions then I relay the serial communication over UDP using a SIM900D module. I initiate the UDP connection to MP, but then I get the message "Getting Params..(sysid 1 compid 1)", which continues for about 1.5 minutes then finally I get a "Connection Failed" message with the following details:

Timeout on read - getParamList
1 Packets where received, but nop paramater packets where received

at MissionPlanner.MAVLink ....

What am I doing wrong?

Here is my code for the Arduino Mega 2560:


Thank you in advance,

Or you could use GoPro/usb Webcam connected to Raspberry pi with usb modem 3g /4g.
Serial connection with APM and ser2net(only TCP) or this which supports UDP :)

If you can make OTG to work as serial connection you can run ser2net on the other side make VPN connection to your ground station to avoid all IP shenanigans from your cell provider. If there is enough bandwidth you can run IP webcam and stream video to your ground station. Any phone supporting OTG should work. Finding old 4G phone can be done for less than $50. Cheaper than drone cell and more powerful.

i was thinking about it, but sooner or later i will feel a need to use a power of full android os(camera,etc, backup gps location).

disassembled phone without screen,battery,etc and casing will be really light and for a plane 20-30g for such a powerful element in the game is nothing :)

Comment by Simon Wunderlin on February 20, 2014 at 10:26am

Milan, this should work. Maybe you want to check the DroneCell, it is a 3G modem that can be connected to the telemetry port. It's much smaller, lighter than a cell phone and requires probably less power. With that said, the DroneCell has not much CPU power ... it's basically just a modem.

Comment by Milan Polimac on February 20, 2014 at 9:05am

please correct me if i am wrong, 

is it possible to build this kind of setup:

APM telemetry port (GND,tx,rx,vcc) >>>> FTDI >>>OTG >>> android phone (usb host) >>> andorid app that till relay from serial to tcp or udp

i think it is much better solution than use of bluetooth inside of aircraft.

i will try today or tomorrow to setup this , but please correct me if this is even possible, i am IT guy weak in electronics.

Hi all, what is the latest wokring code for arduplane/ copter with telemetry? Got the Dronecell 3.0 and APM 2.6. Very eager to try the telemetry over cellular. I think I got everything ready, only missing the code. If anyone could guide me in the right direction, that would be great. Thanks!

Comment by Tim Mulder on November 15, 2013 at 8:53am

Anyone have any thoughts on using this ( for 3g telemetry?
