Dyalf

A Node.js Library to interact with Star Wars Sphero droids

Pair droids with your device

To pair droids with your device for the first time, you need an external tool to find UUID. I use

node blescanner.js

included in this library.

Usage

const dyalf = require('./dyalf');


let r2 = new dyalf.R2D2('4bef2b0786334e2fac126c55f7f2d057');


let main = async () => {
    await r2.connect();
    await r2.openCarriage();
    await r2.closeCarriage();
    await r2.sleep(1000);
    await r2.animate(7);
    for (var i = -160; i < 180; i += 5) {
        await r2.rotateTop(i);
    }
    await r2.sleep(1000);
    await r2.off();
    dyalf.shutdown();
};

main();

Troubleshooting

Use @abandonware/noble npm package to avoid the xpc-connection error.

MacOS won't connect to the droid

Restart your Mac is a valid option! Alternatively:

• Turn off Bluetooth
• Run the following code in your shell

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

• Turn Bluetooth back on

You can automate this procedure using blueutil:

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