tello-api

Description

Node API for the tello drone.

Supporting the 1.3 SDK version

The API if using the dgram sockets under the hood to connect to drone through UDP.

Installation

yarn add tello-api

npm i -save tello-api

Usage

API is working with async/await syntax Currently it's supporting only one command at the time

Typescript example

import { Drone } from 'tello-api'

const drone = new Drone(); // will create new instance with default ports
await drone.connect(); // will init the command and state sockets
const temp = await drone.command('battery?'); // will return battery result

await drone.takeoff() // drone will take off
await drone.up(25) // drone will go up
await drone.land() // drone will land

await drone.disconnect(); // remove all listeners from the sockets

To create an instance with different drone host and ports use the DroneConstructorInput interface as in example with defaults 👇

const drone = new Drone({
    commandHost: 192.168.10.1;
    commandPort: 8889;
    statePort?: 8890;
});

When connecting to the drone, client UDP port on your machine assigned by default. To change that use the optional parameters to connect command: DroneConnectInput interface as in example with defaults 👇

const drone = new Drone();

await drone.connect({
    clientPort: 9888,
    defaultCommandTimeout: 12000 // time in ms 
})

Developing

npm install

OR

yarn

Testing

I'm using the node-tap for testing To run tests npm test should be enough. Config is in .taprc file.

Future Development

• Cover all SDK commands (go, curve, set commands not supported yet)
• Generate API docs from the ts files.
