Windows 10 IoT Core
Windows 10 IoTCore, as implemented on the Raspberry Pi 2 (RPI2) initially came with no WiFi or Bluetooth (BT) connectivity. These were then added as USB dongles but with a limited listed of hardware that worked. RPI3 has built in WiFi and BT. What is the state of play with IoTCore connectivity with the RPI now? Are there any issues?

In the previous articles in this series, a UWP app was developed as an array of XAML buttons that acts as the UI for an app running on a remote embedded or IoT device. Once connected the remote app sends a configuration for the UI as a Json string. Connectivity between the UWP and remote apps over Bluetooth and USB Serial has been covered. In this article connectivity over network sockets is covered. The article includes 101 on TCPIP Network Sockets for UWP and Arduino.
This article reworks the previous few articles that use BT Serial and the connectivity so that USB virtual serial is used for communication. It covers in detail USB Serial connectivity between a UWP app and an Arduino devices as well as with a Windows 10 IoT-Core device (eg RPI).
Turn your old Surface into into a large touchpad. As part 3, add a Text Output control to the UI that can note which button is pressed along with (later on) output from the remote app.

Have you got an old RT Surface 1 or 2 gathering dust and don't know what to do with it?
As I discussed in a previous blog article, the Raspberry PI3 Bluetooth driver for Windows 10-IoT-Core becomes errant and misses updates when the update rate is high. This is a known issue with the RPI. This problem does not exist other Windows 10 systems including the Dragonboard running IOT-Core. This article again discusses the problem and presents a workaround that does work. Includes how to disable/enable a driver using devcon.
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..
A library on Codeplex. Been a long time coming: Arduino sketches and UWP class libraries and apps, focused upon scanning a phone keypad as input (Bluetooth serial) to a UWP app running on a phone, desktop or IoT-Core device.
I did a presentation last Thursday for the Melbourne Azure Meetup.
The slides are at: http://www.slideshare.net/cedriverwiz/windows-10-iotcore-to-azure-iot-suite

Whilst it does not go into great detail about Azure IoT Suite, it covers everything in the leader up to it. including:
AppInstall can be used to install Appx packages on an IoT-Core device This blog covers an updated version of the toolkit for use on the latest Winsider IoT-Core builds.
