With the launch of the Raspberry Pi 3, Bluetooth Low Energy (BLE) is now at our disposal. With BLE, there are a few technologies for implementing one-way beacons that broadcast data. Apple has been pushing iBeacon since 2013, and Google just launched their Eddystone solution last year.
If you’re looking to target Google’s Eddystone on your RPi 3, [Yamir] has you covered. He’s put together a guide on setting up an Eddystone-URL beacon within Raspbian. This type of beacon just broadcasts a URL. Users within range will get a notification that the URL is available, and can navigate through to it. Eddystone-URL works on both iOS and Android.
The process for setting this up is pretty simple. The
hcitool commands do all the work. [Yamir] was even nice enough to make a calculator tool that generates the
hcitool command for your own URL. While is hack is a simple one, it’s a nice five-minute project. It’s also handy for broadcasting the URL of your Raspberry Pi if it’s running a web server as part of a more intricate hack.
