Hello

Please check the firmware version of your tello, update to the last firmware using the tello mobile app and then test again.

In the meanwhile i will try to setup a clean environment and try to recreate this issue.

Thanks a lot!

Thank you very much. my firmware version is 01.04.92.01 and I try to updated to last one (02.05.01.17) but failed. mobile app show updating message by using my own wifi but tello uses local wifi so I can't update firmware when I connect to tello.

I will try again later.

I believe that you can connect to a network with internet access to first download the firmware and then connect back to the drone to upload the firmware.

Since you are running on a older version this might be the issue. The pytello lib is made to work with tello V2.# firmwares

Thank you for video.

I follow the guide and I am sure that my app has a problem.

Every time I switch to Tello and push start, the app show my firmware is [Latest Firmware] and can’t update.

Hi, I am having exactly the same issue as @chaos4ros2 - so I'm also trying to update the firmware but then I'm having the exact same problem even with the app, it tells me 'latest firmware' but in reality I see the firmware version is 01.04.91.01. Did you manage to update the firmware and solve the problem?

Hey again, I think I might have the other half to this puzzle. It seems that firmware 02.X is set only for the tello edu.

I tried with a tello edu, and assuming it's the first connection on its boot it works

Granted, when I do use an edu it seems to only reduce the error to:
error while decoding MB 33 41, bytestream -5.

It seems intermittent, but it's gone away. I haven't been able to get rviz to stream the video topic yet, but I'm going to leave it for now. If you had any insight it would be appreciated (I am trying this on ros-humble which may also be causing issues).

You could likely close this issue, and I can make a new one for this.

Edit: Got it working. I think it was likely that I'm running both rviz and this node in a container. That said, I also did refactor the node initialization in the tello driver aswell, but idk if that changed it ¯_(ツ)_/¯
