Hello all!

I was looking at q-ground control and noticed that mavlink supports up to 255 devices. This got me thinking. How does one go about controlling multiple drones at a physical communication level?

Using the 3dr 915 mhz radios - Can I simply have multiple remote units for the drones and a single usb unit for the laptop? Since mavlink includes a device id would this act like mesh network where each drone and each ground station using the 915mhz frequency can hear all the other signals?

Can anyone help me understand better how this works?

Thanks all!

  • Has anyone figured this out?

  • I am wondering as well, no one ever tried this? I had a look on the datasheet for the used  chipset 

    http://www.hoperf.com/upload/rf_app/HM-TRP.pdf and I can not find any information about multi-link, multi-point.... connection and also nothing in the current firmware https://github.com/tridge/SiK. But I also did not find anything why it should not work.

    I know it should work with the (older) xbee version, would love to get information about it!

  • Hi folks,

    Any feedback on this? We're wondering about the same question. We're using a 433MHZ, but it shouldn't make a difference.


  • Criro - your idea may work but I would like to be able to have all of them speak with a ground control software and each other at the same time.

    It seems you are describing a one to one network when I need something that will allow 1 receiver to listen to many drones and issue commands to many drones at the same time, while also allowing the same for each drone to listen to its neighbors.

  • I was wondering the same thing. I have 4 quads that I want to turn autonomous and i would love to be able to launch all of them at once  and control them from one laptop.
