Controlling a Parrot Mini Drone from Chrome for Android, using Web Bluetooth.

(https://youtu.be/gXu3G3cg52k)

Currently requires Chrome or Opera (watch this space for Samsung Internet support ;-)).

Run the web app up on your dev machine with any simple web server that can serve static files, e.g.: python -m SimpleHTTPServer 8080

Go to chrome://inspect/#devices and enable port forwarding for port 8080. Now you should be able to visit localhost:8080 on your Android device, to see the dashboard.

NB. You can't just point to an IP address because Web Bluetooth requires HTTPS, if not serving from localhost.

If you wish to host a version somewhere, it will need to be over HTTPS. (Previously you needed the Web Bluetooth flag enabled in the browser or to register your site for an origin trial but) it is now enabled by default, since Chrome 56 and Opera 43.

There may be bugs! Please observe the usual caution with drone flying as well as making sure you have a backup method of disabling the drone in the event of a bug! (A technique I have used is to raise something like a strong piece of card up towards the drone from underneath. When it detects it has been touched, the drone should shut down automatically).

• Ensure the drone is switched on and the lights are green.

• Press the 'Connect' button.

• Select your drone name to pair with.

• Now you're in control! Try Take Off, Flip and Land.

I still need to fix taking off multiple times - for now you will need to refresh the page.

If it doesn't work, try switching the drone off and on again, wait for the green lights, and then try the above again. Please note the drone will need to have enough battery life remaining or it may silently ignore commands.

If you still have trouble, you can have the remote debugging tools open in Chrome to see the console logs and this may help you to see where it's going wrong, at least. If you spot any fixes / improvements that could be made, PRs are welcome!

If you are interested to learn more about the API to communicate with the drone, you can find links to docs here.

I am indebted to voodootikigod's rolling spider project for demonstrating how to communicate with the drone. This demo borrows a lot from it.

Thanks also to @beaufortfrancois for collaborating with me to get the demo working better!
