Minidrone-js   
---------------

Minidrone-js is an easy to use drone library for the Parrot
Minidrones. In theory it supports many different Parrot drones
besides Minidrones but this is untested.

This library is loosely based on the work by [fetherston] for
[npm-parrot-minidrone] and [amymcgovern] for [pymambo].

Functionality

This library is designed to support the two-way command communication
protocol used by Parrot drones. It supports receiving sensor updates
and sending commands based on the [xml specification].

[xml specification]: https://github.com/Parrot-Developers/arsdk-xml/blob/master/xml/

Installation

``bash
npm install minidrone-js --save
`

Example

This example will make the drone take-off, do a flip and then land again.

`js
const {DroneConnection, CommandParser} = require('minidrone-js');

const parser = new CommandParser();
const drone = new DroneConnection();


/*
* Commands are easily found by reading the xml specification
* https://github.com/Parrot-Developers/arsdk-xml/blob/master/xml/
*/
const takeoff = parser.getCommand('minidrone', 'Piloting', 'TakeOff');
const landing = parser.getCommand('minidrone', 'Piloting', 'Landing');
const backFlip = parser.getCommand('minidrone', 'Animations', 'Flip', {direction: 'back'});

/* Helper function /
function sleep(ms) {
return new Promise(a => setTimeout(a, ms));
}

void async function() {
await new Promise(resolve => drone.once('connected', resolve));

// Makes the code a bit clearer
const runCommand = x => drone.runCommand(x);

await runCommand(takeoff);

await sleep(2000);
await runCommand(backFlip);

await sleep(2000);
await runCommand(landing);

await sleep(5000);
process.exit();
}();
`

Troubleshooting

#### MacOS won't connect to the drone
- First turn off Bluetooth
- Run the following code in your shell

`sh
rm -v ~/Library/Preferences/ByHost/com.apple.Bluetooth.*.plist
sudo rm /Library/Preferences/com.apple.Bluetooth.plist
`

- Turn Bluetooth back on

Or alternativly using [blueutil]:

`sh
blueutil off
rm -v ~/Library/Preferences/ByHost/com.apple.Bluetooth.*.plist
sudo rm /Library/Preferences/com.apple.Bluetooth.plist
blueutil on
``
