This blog presents a Universal Windows App that connects to an embedded Bluetooth device over the Bluetooth Serial Profile using a genetic Bluetooth USB dongle. This app will run on both a Windows 10 IoT-Core devices such as a Raspberry PI2 and a Windows 10 Desktop. The blog covers in detail the key issues with pairing including where a passkey is required with a RPI2 as well as a Bluetooth primer. Update 1.2: One bug fix (was writing send text twice) and and one code improvement (menu returns DeviceInformation so no need to requery for it.)

The serial pins on the Raspberry PI now have a driver in Windows 10 IoT Core on RPI2!
Publ2shed on Codeplex and GitHub. More details later:Win10 IoT Core Universal Windows App runs on a Raspberry PI 2 (& desktop) that reads some sensors (on an Arduino board) saves to and from Azure Mobile Service
In a previous blog I covered the use of the FTDI D2XX driver on a Windows 10 IoT Core Raspberry PI 2. An issue arose with respect to Startup Tasks. Microsoft have looked into the issue.

There are currently 2 reserved GPIO pins on the RPI2 that ordinarily are SOC (I call native) serial. A future Tx and Rx but not at the moment. Serial is achieved on the RPI2 with Win 10 IoT Core via a USB-Serial device connected to a Host USB port on the RPI2. There are though limitations in that the widely used FTDI chipset is not supported by Microsoft, although we have a solution. An alternative is over Bluetooth but there is an issue there.
The following is the complete Debug output for running the Startup Task. Two versions are shown. One with Managed Code Debugging and one with Native Code Debugging. Mixed is not permitted. An exception is thrown when the FTManager is instantiated. This error is not trapped by a Managed Code (c#) try-catch
In a previous blog I covered the use of the FTDI D2XX driver on a Windows 10 IoT Core Raspberry PI 2. This covered a missing plank from the Win10RPI2 armour that was much called for. It facilitates the use of USB-Serial devices based upon the FTDI chipset of which there are many. Jark took an idea I had to use the FTDI ARM Windows RT D2XX driver for the RT Surface 1 & 2 and created a comprehensive Universal Windows App that used the driver. His GitHub project contains complete instructions to install the driver on a RPI2. This project is though an App. What about a using it in a Startup Task on a headless RPI2? A blocking issue has arisen.
