IOT
After an absence from significant IoT-Core activity, whilst working on a significant phone app (as blogged here) I’m back in the IoT-Core space. Things have changed for the better so here goes. This blog covers my experiences with getting a RPI3 going with the latest Technical Preview build. Tools are now available to simplify setup and there is now a Remote Viewer. As a test UWP app, I have used (after a small modification) the Icons app on Codeplex, Universal Windows 10 SDK App Icons app as blogged in a previous blog. The app was modified because popups (as in MessageBox) are not supported in IoT-Core (Use thereof can cause an app crash in later OS versions). This feature change is covered.

The previous blog explained what needs to be done to be able to deploy and debug apps with latest build for IoT-Core (Build 10586). On the Microsoft IoT forums it was reported by some that if they didn’t set up as in the previous blog they got a pin request. This blog provides some detail as to how the Universal (Unencrypted Mode) authentication works. It also explains why some got the PIN request.
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 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
A Universal Windows App that mimics the web portal to a Windows 10 IoT Core device. Makes use of the web portal through REST and uses JSON to process the response for display. Can get ipconfig, processes, installed app, default app, OS info etc… All in an app.
In my previous blog Windows 10 (including IoT) USB HID device identification was covered in detail. This included an app that takes the relevant IDs for an HID device and checks whether it is present on the system. Two of the IDs could be looked up via a menu as they come an HID Usage table. The menu data was loaded from a JSON (text) file and translated using Linq to a list that is the Xaml data source binding for the menu. This blog demonstrates the mechanism for loading JSON data from a text file into an Xaml ComboBox.
This blog discusses a UWP (Universal) app that enumerates the drivers on a Windows 10 system (including IoT). Its like the Windows Device Manager app. Full source code is available.
