    Station mode and sockets

    The UDP forwarder will only forward UDP streams, like the Tello video stream. There are several other packages to control the tello, such as hanyazou/TelloPy or clydemcqueen/tello_ros

    Station mode and sockets

    There's no broadcast capability that I know of. For most swarm use cases each drone needs unique instructions, so this isn't a big limitation. In my case, I'm using the video stream from each drone to do precise localization using fiducial markers. Video streaming isn't supported in station...

    Station mode and sockets

    @twissmueller No. That was pretty much the entire response.

    Station mode and sockets

    Update: I got an email response from Ryze: "... at present, when the tello enters the station mode, the streamon instruction is not supported."

    Ap command

    Ap command

    @robfero At this point I don't think video is supported in station mode. I set up a wlan sniffer to watch all wlan frames going to/from the Tello EDU, and I don't see evidence that it's sending video in station mode. Setup: -- used airmon-ng to set up monitor mode on my wifi card with the...

    ZigBee Support?

    AFAIK, usual port is 8889. Port 9999 seems to be listening w/ TCP. I'm not able to get any info from telnet'ing into that port, however.

    Ap command

    Hi, @robfero -- were you able to get video to work while the drone was on a different network? Thanks.

    Station mode and sockets

    Update: I got the "ap" command to work on a single EDU drone, and I'm able to put the drone into SDK mode and get telemetry data on port 8890. However, I'm not receiving video packets on port 11111. Using wireshark, I do see occasional UDP packets arriving on port 8899. The payload is 12 bytes...

    SDK responses

    1. rc commands set all 4 channels at once 2. rc commands set velocity, where as the named commands set target position.** Velocity is more useful for my application. **The docs indicate that the named commands (left, up, etc.) set a target delta, though I haven't played around with these, and...

    SDK responses

    Thanks for the confirmation.

    SDK responses

    Are you seeing responses to "rc a b c d" commands? I'm not seeing those. I am seeing responses to commands like "takeoff", "battery?" and so forth.

    ROS2 / C++ driver for Tello

    Hi, folks: I've posted a ROS2-Crystal Tello driver at clydemcqueen/tello_ros I've tested it on Ubuntu 18.04, but it should be possible to get it running on any ROS2-supported platform. If you've never heard of ROS2, you can learn about it here: ROS2 Overview The driver is written in C++, so...

    Station mode and sockets

    Has anybody worked with 2+ Tello EDU (SDK 2.0) drones in "station mode" (sharing a single access point)? A few questions: 1. Presumably the drones use DHCP to get new IP addresses. How does the controller discover the assigned IP addresses? 2. Do all of the drones send video packets to...

    Camera intrinsic parameter

    I don't know of any way to pull this data from the SDK. I ran a camera calibration using ROS tools. This was the resulting camera calibration: camera_matrix = numpy.array([[921.170702, 0.000000, 459.904354], [0.000000, 919.018377, 351.238301], [0.000000, 0.000000, 1.000000]]) distortion =...
