A text-based DJI Tello Emulator
A DJI Tello text-based emulator. Listens to an UDP port and executes a subset of Tello commands. It is based on a fork of tello_sim and relies on plotext to plot data on a terminal.
I needed a way to execute integration tests quickly and reliably, without the hassle (and potential harm) of connecting to a real Tello. Text-based plots allow to easily visualize the flight route.
Use Docker to build this image docker build -t tello-text .
In order to properly simulate the connection interface of a Tello, it is necessary to expose an UDP port when running the image
docker run -p 18889:18889/upd -it tello-text
If the emulator was started correctly it will log the following message
Connecting...
Emulator listening on 0.0.0.0:18889
It is now possible to test commands, for example by using a UDP client nc -u localhost 18889
Tello commands are text-based. Any emulation session will be started/reset with command and terminated with halt.
Tello Text supports the following commands:
| Command | Drone action |
|---|---|
| command | setup drone/reset flight data |
| takeoff | drone takes off |
| land | drone lands |
up z |
moves up for z cm |
down z |
moves down for z cm |
left y |
moves left for y cm |
right y |
moves right for y cm |
forward x |
moves forward for x cm |
back x |
moves back for x cm |
cw deg |
rotates clockwise for deg degrees |
cw deg |
rotates counter-clockwise for deg degrees |
flip dir |
flips in a direction (l, r, b or f) |
| halt | Closes connection and stops emulator |
Some possible improvements are:
- expand command set
- add cli support
- export flight data
No Tello was harmed while hacking this repo.
