Motivation
Provide an async promise based unofficial sdk for the tello drone based on the official documentation.
Installation
add it to your project using npm install tellojs --save or yarn add tellojs
Usage
this sdk provide functions when you import for the next capabilities:
const sdk = require('tellojs')
const x = number,
y = number,
z = number,
speed = number,
yaw = number,
start = {x, y, z},
end = {x, y, z},
ssid = string,
password = string
//CONTROL COMMANDS
await sdk.control.connect() // Enter SDK mode.
await sdk.control.takeOff() // Auto takeoff.
await sdk.control.land() // Auto landing.
await sdk.control.emergency() // Stop motors immediately
await sdk.control.stop() // Hovers in the air
await sdk.control.move.up(x) // Ascend to “x” cm.
await sdk.control.move.down(x) // Descend to “x” cm.
await sdk.control.move.left(x) // move left to “x” cm.
await sdk.control.move.right(x) // move right to “x” cm.
await sdk.control.move.front(x) // move forward to “x” cm.
await sdk.control.move.back(x) // move backwards to “x” cm.
await sdk.control.move.go(end, speed) // fly to x y z in speed (cm/s)
await sdk.control.move.curve(start, end, speed) // fly to x y z in speed (cm/s)
await sdk.control.rotate.clockwise(x) // rotate clockwise 'x' degrees.
await sdk.control.rotate.counterClockwise(x) // rotate counter clockwise 'x' degrees.
await sdk.control.flip.left() // Flip to the left.
await sdk.control.flip.right() // Flip to the right.
await sdk.control.flip.back() // Flip in backward.
await sdk.control.flip.front() // Flip in forward.
//SET COMMANDS
await sdk.set.speed(x) // set speed to x cm/s
await sdk.set.rc(x, y, z, yaw) // Send RC control via four channels.
await sdk.set.wifi(ssid, password) // Set Wi-Fi with SSID password
//READ COMMANDS
await sdk.read.speed() // Obtain current speed (cm/s).
await sdk.read.battery() // Obtain current battery percentage.
await sdk.read.time() // Obtain current flight time.
await sdk.read.height() // Obtain get height (cm)
await sdk.read.temperature() // Obtain temperature (°C)
await sdk.read.attitude() // Obtain IMU attitude data
await sdk.read.barometer() // Obtain barometer value (m)
await sdk.read.tof() // Obtain distance value from TOF（cm）
await sdk.read.acceleration() // Obtain IMU angular acceleration data (0.001g)
await sdk.read.wifi() // Obtain Wi-Fi SNR.
//STREAM STATE
const stateEmitter = sdk.receiver.state.bind() // Binding to port of state
stateEmitter.on('message', res => console.log) // React to messages on received
sdk.receiver.state.close() // Stop receiving messages
//STREAM VIDEO
const videoEmitter = sdk.receiver.video.bind() // Binding to port of video
videoEmitter.on('message', res => console.log) // React to messages on received
sdk.receiver.video.close() // Stop receiving messages
/*
Example output of state:
{
pitch: 1,
roll: 0,
yaw: 0,
speed: { x: 0, y: 0, z: 0 },
temperature: { low: 51, high: 53 },
tof: 6553,
heigh: 0,
battery: 87,
barometer: 24.65,
time: 0,
acceleration: { x: 16, y: 3, z: -990 }
}
Example output of video: is binary ;)
