    Tello Firmware refuses to download

    Yes - working now for me too. The update does seem to have markedly improved the smoothness of take-offs (which seemed to have got worse at some point over the last couple of firmware releases). Prior to this update my Tello was jumping around a lot as soon as it left the ground; now it...

    Unofficial Standalone Golang Tello Package Released

    This is normal behaviour(!) for the Tello, and nothing to do with my package. See this thread and this one for more details.

    Unofficial Standalone Golang Tello Package Released

    It's difficult to guess what's causing that without seeing the code you are using to make the calls into the tello package. My first guess would be that you haven't successfully established a network connection to the Tello via eg. ControlConnectDefault(), and a video connection via eg...

    As Yet Undiscovered Commands

    I have done two things, fixed the package (library) to send the FULL range of joystick values as they were accidentally halved before, and changed the app I am working on to always send maximum joystick values when the stick reads over 50% (a crude 'response curve' I suppose). It's working now.

    Unofficial Standalone Golang Tello Package Released

    I have just released v0.9.1. Besides some minor documentation changes this release fixes the joystick mapping function so that the full range of values is now sent to the Tello. This means it is now possible to use the 'engine start' function via joysticks in the lower-inward position for more...

    As Yet Undiscovered Commands

    I think that explains why - even with game controllers - my API and some of the others aren't triggering the engine start. On game controllers, as you move a stick away from one of the major compass points (N, S, E, W) the values go off maximum, i.e SE is not max S + max E but a bit less than...

    As Yet Undiscovered Commands

    Do you have any idea what the stick value range is for this to activate? I can't seem to get it to work with a game controller using my Go API.

    As Yet Undiscovered Commands

    No - that's not what this is about. Here we are trying to discover some commands that are probably built-in to the Tello firmware, but have not so far been identified.

    As Yet Undiscovered Commands

    It seems that, despite all our efforts thus far, there must be some undiscovered commands for the Tello. The currently-known commands are listed at Low-Level Protocol on our wiki. Perhaps we could list here the ones that seem to be missing and see if anyone has any ideas? There are some...

    instead of takeoff, want to use start and up and down API to start and control Tello moments

    I suspect this would be achieved via an, as yet, undiscovered command to the Tello. I'll start a new thread about these commands.

    Interested in a Windows Desktop for the Tello?

    Hmm... The trouble with having keyboard control is that I don't see an intuitive way to handle speed control, so I was going to keep this application controller-only. Unless you have a good idea how it might work ? :sneaky:

    Interested in a Windows Desktop for the Tello?

    Nice idea, but I don't have such a device. Does it behave like a game controller when connected to a PC via USB?

    Interested in a Windows Desktop for the Tello?

    I'm working on an Windows (and Linux) desktop application for flying the Tello. It would be helpful to know what controllers people would like to use... Let me know what type if it's not on the list.

    Accurate Tello position data

    It doesn't, 92 is the yaw - so it's correct.

    Unofficial Standalone Golang Tello Package Released

    Hi @FlandersNed , Thanks for the detailed report. Firstly, you are pushing the auto-flight funcs pretty hard by asking them to move the drone just 50cm - the tolerance built-in to the package (exported as AutoXYToleranceM) is 30cm. I found that figure by experimentation - much lower and the...
