    Tello edu takeoff problem

    Now I have the same problem. I have two Tellos, one EDU and one normal. I flew them without any problems, did a swarm, and so on. Now, after a longer break, I wanted to fly again. The normal Tello works, but the EDU doesn't. In tello3.py I enter command, get OK. battery? --> I get the...

    Onboard Raspberry Pi

    Any luck yet? I experienced spinning a few times, not related to the Raspi. Maybe it was just coincedence. You might try CG calibration (in the original Tello app). Maybe you had WIFI disturbances, this could be made worse by the Raspi.

    [Download] Official Ryze Tello EDU Mission Pads

    It does have the "3" printed on it. It really should be visible. And I did not change the mdirection, so it should look down. Tello was roughly 60cm above the pad. Thanks for the hint, I will look at the telemetry stream.

    [Download] Official Ryze Tello EDU Mission Pads

    So far, I did not yet have any success with the mission pads. I found my original ones again, so it is definitely not the fault of the printed cards. I issue "command", then "mon", "takeoff" and and wait until I get the ok after takeoff. The pad is below Tello, so Tello should see it. I...

    SWARM of 2 Tello Drones (Simple Tello / Non-EDU Version)

    It works fine on the Raspberry Pi. When I tried my script on a notebook running Mint 19.10, I experienced a strange situation: I was able to talk to both Tello's like sending "command" or "battery?". The both replied. But when I wanted to takeoff or send "rc -100 -100 -100 100" to start the...

    SWARM of 2 Tello Drones (Simple Tello / Non-EDU Version)

    Well, I have not yet tried the receive side, but as you have two (or more) sockets tied to two different network interfaces (or more), you should be able to separate the incoming streams. When sending commands, it is the same situation: Both (or all, if you connect to more than two) Tellos have...

    pattern editor for robomaster TT

    Hi, it seems that you completely misunderstood my posting. I do not use a camera, I don't read any patterns, I put nothing on any wall or floor. It does what I wrote and that's it.

    pattern editor for robomaster TT

    Hello everybody, I have written a simple editor for creating patterns to be shown on the Robomaster tellotalent extension. Nothing fancy, just a little tool I quickly wrote to create a few patterns for myself. Maybe you find it useful, too. You can find it here: GitHub -...

    SWARM of 2 Tello Drones (Simple Tello / Non-EDU Version)

    I tried to attach the python file, but it is not shown here. So I copy&paste the code here. It is definitely far from perfect, just a proof of concept. # tello demo by Ryze Robotics, modified by Martin Piehslinger import threading import socket import sys import time...

    SWARM of 2 Tello Drones (Simple Tello / Non-EDU Version)

    I made it! 1) It really works under Linux only (tested on Raspberry Pi). When I try it under Windows, setsockopt reports an illegal argument. 2) I did not find any documentation on option name 25, but it works 3) The option value is the name of the network adapter. wlan0 and wlan1 on the...

    SDK 3.0 for Tello EDU

    Meanwhile I have a TT. The "motoron" command sets the speed of the propellers lower than I did with "rc -100 -100 -100 100" and followed by "rc 0 0 0 0" .

    SWARM of 2 Tello Drones (Simple Tello / Non-EDU Version)

    Thanks a lot! I own a normal Tello and an EDU, and I thought about doing a swarm using a second wifi dongle. It should work by setting the EDU into station mode, but your solution is a lot easier. And it opens up swarm programming for non-EDU users. Does anyone know how to get the equiivalent...
