Robotroller.iOS Stream failed error while connecting to BLE

Hi,

I am working my way through the Xamarin's Monkey Robotics Robotroller example.
I followed the tutorial steps, deployed the Netduino (v3) code now I'm getting following error

Adapter: Waiting for state: PoweredOn
adapter.StartScanningForDevices()
Adapter: Starting a scan for devices.

Seems to me like the app is able to discover the BLE device but failed to establish a connection with it.

ServiceId = new Guid ("713D0000-503E-4C75-BA94-3148F18D941E") is not being found on the BLE device, which has "Device Information" and "TI SensorTag Smart Keys" services.

Have I made a silly wiring/right device mistake?
