What is best way to add bluetooth low energy (BLE) to XAMARIN.IOS: CoreBluetooth or BLE plugin?

I've seen 3 plugins:
WOJCIECH
ARITCHIE
XABRE

But the first 2 don't build. And the 3rd crashes on my iPhone.

So I want to know if it's less work to just implement CoreBluetooth on my Xam.IOS app or to debug those plugin problems.
