This is the 2nd part in a 3 part series. In this part we will use an existing demo app to understand how things should look. We see how to emulate an Eddystone beacon using a node package.
You can find the first part here.
Get the hardware
There are quite a lot of getting started hardware development kits out there. Each one has it's pros and cons, and in the long run you'll end up owning multiple such devices. But for the sake of this blog post I am going to focus on using the cheapest or most easily available hardware to try out actual beacons.
If you own one of the recent MacBooks you are in luck as you don't need to buy anything. Go to About this Mac -> System Report -> Hardware -> Bluetooth.
If it says "Bluetooth Low Energy Supported: Yes", you are in luck.
If your Mac doesn't have support for BLE or you own a Linux machine, I suggest you get a cheap USB dongle. I have used the one from Adafruit and it's great value for money.
