Hello all,

I am new in this forum and this is my first post.
If I understand correctly, the RMTT expansion kit includes also a distance TOF sensor. See this link:
I would appreciate it if somebody can show me how this can be activated.

In the ROBOMASTER TT SDK 3.0 User Guide, there is a Tello command (?)
" EXT tof? Read the tof value. tof xxxx The unit of xxx is mm. It returns 8192 if the detection range is exceeded."

I am not sure if this is related to the forward TOF sensor.
Rhanks!

Hello all,

I finally manage to activate and use the sensor distance TOF of the Multicopter upgrade kit after I update the Tello TT (or Tello EDU) firmware to v02.05.01.19 Date: 2022.05.07!!
For sure you have to have the Multicopter upgrade kit Suitable for DJI RoboMaster TT has to be installed/connected in advance.
I wrote a simple python script to send the command "EXT tof?" to the Tello and to get the response which is the distance of the TOF sensor to the object in front of the Tello.
Then the python code will send a command to the Tello to move back when the sensor is reading there is an object in front of the Tello whihc is 500 mm or less..
So basically something similar to the youtube video I posted above.
