I'm getting the same exception when deploying my app to a Motorola DROID RAZR (API 16). It appears the exception is happening when I create the adapter: new Robotics.Mobile.Core.Bluetooth.LE.Adapter(). Have you found a solution or workaround?

I am getting the same error on my Huawei y300 with API 16.

Might it be because BLE was introduced in Android 4.1 (API 18)?

Yes it was - we ended up targeting a minimum API of 18.
