Windows 10 IoT Core
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
The sample app (A UWP app communicating with an Azure IoT Hub using TPM): https://github.com/djaus2/AzureHubRegisterIoT
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.
The Week or Two That Was
DAVID JONES V1.1
Some of the issues I have been looking at over the last week or so.
In the previous two blogs I discussed using the Web Portal running on a Windows 10 Phone to remotely or in-phone install and Universal Windows Platform app. In this blog I discuss options for install UWP app packages on Windows 10 IoT devices. This is a work in progress as I have not had success some of these methodologies.
The Dragonboard 410C from Arrow has been certified for Windows 10 IoT-Core and comes with Android installed. This blog takes a close look at the board’s features. Subsequent blogs will look at using the board in Android and IoT-Core modes.
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.
