# Tello Low-Level Protocol Wrapper
A wrapper for [Tello Low-Level Protocol](https://tellopilots.com/wiki/protocol/) for Java applications.
## Usage
You can access the Tello Low-Level Protocol by simple
interface
of [Facade](./src/main/java/com/xpfriend/tydrone/core/Facade.java).
- **run** : Start communication with the Tello.
- **entryCommand** : Sends a command to Tello.
- Supported Commands:
- **takeoff**
- **land**
- **stick rx ry lx ly speed**
- **rx:** (left) -1 < 0 < 1 (right)
- **ry:** (backward) -1 < 0 < 1 (forward)
- **lx:** (down) -1 < 0 < 1 (up)
- **ly:** (ccw) -1 < 0 < 1 (cw)
- **speed:** 0 (slow) or 1 (fast)
- **picture** - Take a picture and save the jpeg file in the `~/Downloads` folder.
- **pickImage** : Get a video frame image (960*720 RGB24) as a byte array.
- **getStates** : Get the Tello states as text like: `bat:%d;lit:%d;wifi:%d;yaw:%d`
- **setRecording** : If `true`, video recording will start; if `false`, the video will be saved in
the `~/Downloads` folder.
## Example
For example, the operation "take off, take a picture, and land" would be the following code:
```java
public class Example {
@Test
public void testPicture() throws Exception {
try (SimpleMain main = new SimpleMain()) {
// start communication with Tello
main.run();
Thread.sleep(2000);
// takeoff
main.entryCommand("takeoff");
Thread.sleep(3000);
// take a picture
main.entryCommand("picture");
Thread.sleep(3000);
// land
main.entryCommand("land");
}
}
}
```
