YouTube: Mind+ Tutorial How to connect and run code on Robomaster Tello Talent on Mind plus software

Update Drone Firmware

Can only be done through the phone app!
Download the newest Firmware in the App while still connected to the internet - before connecting to the drones wifi
Connect to the drones Wifi (TELLO-xxxx) without the extension module connected!
Under the app settings update firmware

Modify Extension Module Wifi AP

Connect only the extension module with a usb cable to your PC
Open the Mind+ software
Under Extensions (Bottom left) select “RoboMasterTT (ESP32)”
Then change the Wifi AP to something like below and press upload

HINTS

When the drone is set to STA / connect to router mode with the switch on the extension module, the propellers will start spinning once connected. If you want to stop the propellers simply lift the drone.
