Android 5 doesn't have Web Bluetooth enabled by default because Google were worried about permissions (Android 6 lets an app ask as and when it needs access to some device, and in 5 you had to ask at install time).
You can do it though, but you have to manually install Chrome - have a look at the page linked from the Getting Started guide: http://stackoverflow.com/questions/34810194/can-i-try-web-bluetooth-on-chrome-for-android-lollipop
It's a bit involved, but that page is the one linked directly from The Web Bluetooth page
