Overview
The TT SDK connects to drones via Wi-Fi UDP protocol, allowing users to control drones through
text commands.
After installing the RoboMaster SDK, users can control the TT product, including the open-source
TT controller and the drone itself. For specic instructions, visit the following website:
https://robomaster-dev.readthedocs.io/latest/
Safety Function
After Tello executes the current command, if no command input is received (other than the [TELLO]
battery?" command sent by the open-source controller for the battery status) within 15s, it will
automatically land.
Resetting Wi-Fi
In the power-on state, long-press the power button for 5s, during which, the drone will reboot after the
status indicator goes out. When the status indicator quickly ashes yellow, the SSID and password of
the Wi-Fi network will be reset to their factory default settings, with no password required by default.
Architecture
Users can use a Wi-Fi network to connect the Tello drone to a PC, Mac, or mobile device.
