Even if I had a DroneCell and even if I had the created a link for two-way telemetry I would only get reception when I crashed thanks to not being allowed to fly near civilisation. Is this really worth £1000 worth of effort when reception should be sketchy is used legally?

 

I totally agree in having it on standby and if a crash is detected it send you a text with info about the crash so you can try to find it.

The DroneCell works at much higher altitudes... you could get telemetry in a lot of areas with varying conditions. I could see it really benefiting those that fly FPV.

I to am interested in seeing this thing work... I myself will try to get something working here in the future, once I to purchase a drone cell... The voltage and currents are not the problem, because there or circuits that can voltage sift or step up to step down voltage and or current... On their website the have generic communications code that shows how they would implement each of the communication ways... I.E. send text or emails or such etc... they also share how they would use UDP and TCP/IP and all that good stuff so I think in the end, it will be the coding of the APM to the drone cell which will be the only problem... I am just now starting to look into the coding of APM...

 

If we can get a team going to work on this, that would be great... I would like to help in any way I can...

I'm willing to fund this project if we can get something done in a short time frame.

OK, so I have done a bit of research and There has been talks and actually someone working on this... How much are they working on it, this is unknown... So far sparkfun has created pretty much the exact thing as the Drone cell, but I think the voltages it can handle are different... I also found out that you will need a server set up to get/give an IP and to get or send the UDP packets which will require a port number...

Just find me a Dronecell and i'll get it done. The problem is they're all out of stock now. I've tried finding an older phone with a serial port and built-in TCP stack, but they're very hard to find and not a very elegant solution.

 

I lost a arduplane powered plane for a few hours yesterday and it made me look into Dronecell in detail. The docs are pretty good, and it looks like it has a simple transparent data mode that would make it easy to pass a serial connection to a 3G connected laptop in the field. This could work either directly or using a hosted server running a simple application that relays the packets on two different ports to and from the dronecell and laptop.

Any updates on this? I'm thinking about trying this with an old Nokia phone that has serial in/out. Did anyone try connecting a generic serial device to the serial 3 port on the Ardupilot Mega?

Chris,

I am interested in this as well... I have found some information but I have posted above in an earlier post... I wasn't able to start on this because I didn't have the components to do such... Now that I finally got my circuits for the APM I am now going to buy one of these and try to start working on this...

Before I jump right in and try to figure this out...  Can someone tell me, is it up to the ground station or is it up to the APM or both? What I mean is, does the ground station or the APM  have anything to do with or able to handle tcp/ip or UDP packets? If not, then we will have to write code for the APM to use the drone cell and with the ground station...

Both APM planner and my GCS (HK GCS) can do TCP and UDP. UDP is not for 2-way as the order of the packets cannot be guarenteed....so you'll want to do TCP.

I think this "transparent mode" looks very interesting - and easy ?
