I have been trying to connect an iPhone 5 to OSX Chrome (Version 38.0.2096.0 dev) over BLE using chrome.bluetoothLowEnergy API.
I\'m using BLE Utility on my iphone
The BLE implementation for the Mac is not complete yet as far as I know. A good place to follow the development of the API is on the Chrome issue tracker. This is a link to the issue related to the Mac one specifically. To see all the bluetooth changes, just search for bluetooth under open issues.
