Description: TT detects the mission pad with ID 2 with the enabled mission pad detection function.
If recognition succeeds, the drone will y to the coordinate point (0, 0, 100) and then to the coordinate
point (100, 100, 100) in the mission pad coordinate system along an arc at a speed of 40 cm/s.
If recognition fails, it will hover, return "Error. Not valid marker", and wait for the next command.
* The arc is the short arc of the only circle formed by the current position of the drone, (0, 0, 100)
and (100, 100, 100).
If the three points are on a straight line or the radius of the resulting circle is not within the range of
0.5 m - 10 m, an error is returned.
Command Description Possible response
jump x y z speed yaw
m(id1) m(id2)
Tello ies to point (x,y,z) of the mid1 coordinate
system and hovers, recognizes the mid2 mission
pad, and rotates to the set yaw value at position
(0,0,z) in the mid2 coordinate system
ok/error + Error
message
Example: jump 100 100 100 40 90 m1 m2
Description: TT detects the mission pad with ID 1 with the enabled mission pad detection function.
If recognition succeeds, TT will y to (100, 100, 100) in the mission pad coordinate system at the
speed of 40 m/s, hover, and attempt to recognize the mission pad with an ID of 2. If this mission pad
is recognized, the drone will rotate to a position 90° relative to the x-axis in the coordinate system of
the ID 2 pad.
If recognition fails in either recognition process, the drone will hover and return "Error. Not valid
marker".
TELLO Status
When the host computer sends "command" to Tello UDP port 8889 to enter the SDK mode, Tello will
send Tello status information to UDP port 8890 of the host computer. The data is a string, and the
content is as follows:
“mid:%d;x:%d;y:%d;z:%d;mpry:%d,%d,%d;pitch:%d;roll:%d;yaw:%d;vgx:%d;vgy%d;vgz:% d;temp
l:%d;temph:%d;tof:%d;h:%d;bat:%d;baro:%f;\r\n”
Description
• Mid: For the detected ID of the mission pad, -2 will be returned if the mission pad detection
function is not enabled, and -1 if the function is enabled but no pad is detected.
• x: The x-axis coordinate of the drone relative to the detected mission pad (in centimeters). -200 will
be returned if the mission pad detection function is not enabled, and -100 if no pad is detected.
• y: The y-axis coordinate of the drone relative to the detected mission pad (in centimeters).
-200 will be returned if the mission pad detection function is not enabled, and -100 if no pad is
detected.
• z: The z-axis coordinate of the drone relative to the detected mission pad (in centimeters).
-200 will be returned if the mission pad detection function is not enabled, and -100 if no pad is
detected.
• mpry: The pitch, yaw, and roll angles and degrees of the drone in the mission pad. If the mission
pad is not detected, 0 will be returned.
