Several months ago I published a UWP app on GitHub that interacted with a Texas Instruments CC2650STK SensorTag using the Bluetooth Low Energy (BLE) API. It was based upon a previous Microsoft sample UWP app for interacting with an earlier TI SensorTag. Whilst the new app ran well on the Windows 10 Desktop and Windows 10 Phone, it was found to be erratic on the Raspberry Pi3 running Windows 10 IoT-Core.. working well some times but errant other times. Windows 10 Creators Edition added a key feature to BLE, namely the ability to connect to a device that is advertising without being paired. This blog examines the erratic nature of the RPi3 with BLE and investigates whether this is solved with the Creators Edition. In so do a comparison is made between between BLE Paired and Unpaired connectivity in the UWP app development context..
