Provide an async promise based unofficial sdk for the tello drone based on the official documentation.
add it to your project using npm install tellojs --save or yarn add tellojs
this sdk provide functions when you import for the next capabilities:
constsdk=require('tellojs')constx=number,y=number,z=number,speed=number,yaw=number,start={x, y, z},end={x, y, z},ssid=string,password=string//CONTROL COMMANDSawaitsdk.control.connect()// Enter SDK mode.awaitsdk.control.takeOff()// Auto takeoff.awaitsdk.control.land()// Auto landing.awaitsdk.control.emergency()// Stop motors immediatelyawaitsdk.control.stop()// Hovers in the airawaitsdk.control.move.up(x)// Ascend to “x” cm.awaitsdk.control.move.down(x)// Descend to “x” cm.awaitsdk.control.move.left(x)// move left to “x” cm.awaitsdk.control.move.right(x)// move right to “x” cm.awaitsdk.control.move.front(x)// move forward to “x” cm.awaitsdk.control.move.back(x)// move backwards to “x” cm.awaitsdk.control.move.go(end,speed)// fly to x y z in speed (cm/s)awaitsdk.control.move.curve(start,end,speed)// fly to x y z in speed (cm/s)awaitsdk.control.rotate.clockwise(x)// rotate clockwise 'x' degrees.awaitsdk.control.rotate.counterClockwise(x)// rotate counter clockwise 'x' degrees.awaitsdk.control.flip.left()// Flip to the left.awaitsdk.control.flip.right()// Flip to the right.awaitsdk.control.flip.back()// Flip in backward.awaitsdk.control.flip.front()// Flip in forward.//SET COMMANDSawaitsdk.set.speed(x)// set speed to x cm/sawaitsdk.set.rc(x,y,z,yaw)// Send RC control via four channels.awaitsdk.set.wifi(ssid,password)// Set Wi-Fi with SSID password//READ COMMANDSawaitsdk.read.speed()// Obtain current speed (cm/s).awaitsdk.read.battery()// Obtain current battery percentage.awaitsdk.read.time()// Obtain current flight time.awaitsdk.read.height()// Obtain get height (cm)awaitsdk.read.temperature()// Obtain temperature (°C)awaitsdk.read.attitude()// Obtain IMU attitude dataawaitsdk.read.barometer()// Obtain barometer value (m)awaitsdk.read.tof()// Obtain distance value from TOF（cm）awaitsdk.read.acceleration()// Obtain IMU angular acceleration data (0.001g)awaitsdk.read.wifi()// Obtain Wi-Fi SNR.//STREAM STATEconststateEmitter=sdk.receiver.state.bind()// Binding to port of statestateEmitter.on('message',res=>console.log)// React to messages on receivedsdk.receiver.state.close()// Stop receiving messages//STREAM VIDEOconstvideoEmitter=sdk.receiver.video.bind()// Binding to port of videovideoEmitter.on('message',res=>console.log)// React to messages on receivedsdk.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 ;)*/
