IoT With Azure - Enterprise Cloud Road Show 2015

I got an opportunity to present a session on Internet of Things (IoT) with Azure in the Enterprise Cloud Road Show 2015 event conducted by Microsoft. All the sessions taken by MVPs. Thanks Biplab Paul - Community Manager and Gandhrav Rawat for this opportunity. I have shared a snapshot of this Event.

Global Azure Bootcamp 2015 - Microsoft IoT Solutions with Azure



Global Azure Bootcamp is a one day world-wide event on 25th April, driven by Microsoft Azure experts and community enthusiasts, to help thousands of people get up to speed on developing Cloud Computing Applications for Azure. This event is organised by Karthikeyan Anbarasan (MVP) through Chennai Microsoft User Group (CMUG). I got an opportunity to take a session on “Microsoft IoT Solutions with Azure” with a live demo on accessing Azure Event hubs and Stream Analytics using Intel Galileo with sensors – Windows IoT. 
You can refer the previous blog  Windows IoT on Galileo – Using Event Hubs and Stream Analytics for source code.


Thanks CMUG!!!

Windows IoT on Galileo – Using Event Hubs and Stream Analytics



This blogs explains you on how to access Azure Event hubs from Galileo integrated with Adafruit 10-DOF IMU sensor board and using Azure stream Analytics to pipeline the sensor data stream to Azure storage services. 

Prerequisites

WEC2013 - e-consystems Bluetooth LE stack

e-con systems has developed its own Bluetooth LE stack for Windows Embedded compact 2013. Hope this will take Windows Embedded compact 2013 platform to a newer market place like healthcare, fitness, security and home entertainment industries. Please see the below link to know more.

Also see the below demo video on e-con systems Ankaa development kit ( iMX6 SOM based dev kit) running on WEC2013 with TI Bluetooth LE Sensor Tag.

Windows IoT on Galileo – Using Event Hubs (Connectthedot.io)



An interesting open source project going on Microsoft Open technologies named connectthedot.io.  


Fig) Connectthedot.io
This is intended to help developers to connect small devices to Microsoft Azure and implementing data analytics with Azure services such as Event hubs, Stream Analytics and Machine Learning.

One interesting thing I found from the project is, we can access Azure Event hubs from Galileo Windows IoT using simple C++. Here is the link for the sample application created using “Galileo Wiring App”.

This application get the data from sensors and push it as events to Azure Event hub. This application creates JSON packets and send it through AMQP protocol to Azure Event hub. Challenging part (sending data from Galileo) is released by Microsoft Open Technologies. Receiving part should be a cake walk. Sample for receiving data from Windows 8.1 PC or WP8.1 is already given in MSDN using Azure .Net SDK. 

I used azurestorage services for earlier demo/blogs with Galileo. Now I am going to try this application with my sensor module connected with Galileo. Hope you can also enjoy this.

Windows IoT on Galileo – Accessing Azure storage services



Now Galileo is capable of accessing azure storage services after several tries and tweaks. As you know Windows developer Program for IoT released the Casablanca C++ REST SDK for accessing cloud services from Galileo but this is not sufficient to access azure services and we need to port or develop another layer on top of it to access specific Azure services. I searched and fortunately found a C++ library that can specifically made to access Azure storage services and again that is using the Casablanca C++ REST SDK. Wow!!!. But this happiness was not withstood for long time after building it and running it simply on Galileo. Let’s get hands dirty!!!

Prerequisites

  • Supported for both Intel Galileo Gen1 and Gen2.
  • Latest OS update released on 21-Nov-2014 (common .wim for Gen1 and Gen2) for    lightning (improved performance on I2C, SPI, and UART etc..) 
  • Visual studio 2013 with Windows IoT SDK (Visit: windowsondevices.com for more details) and Microsoft IoT C++ SDK and its dependent NuGet Package is required.
  • NuGet package for C++ REST SDK (Casablanca) Version ≥ 2.0.1 (tested with version    2.0.1 and 2.2.0)
  • Source code for C++ REST SDK. Go through the instructions given in the below link.

Windows IoT on Galileo – Connecting Adafruit 10DOF IMU Breakout Part-2



This blog is the continuation of the previous blog Windows IoT on Galileo – Connecting Adafruit 10DOF IMU Breakout Part-1 and explain you on the changes required on the source code to support with new OS update ( A common OS version for both Galileo Gen 1 and Gen2) and SDK update released on Dec 2014. Updated project is available on the following link in the codeplex. It can support for the older version of OS image for Gen 1 using Galileo SDK and lightning version of OS update for both Gen1 and Gen2 with Microsoft IoT C++ SDK. https://adafruit10dofgalileo.codeplex.com/

Development Environment
·         Supported for both Intel Galileo Gen1 and Gen2
·         OS updated released on 21-Nov-2014 (common .wim for Gen1 and Gen2) for lightning (improved performance on I2C, SPI, and UART etc..)
·         Visual studio 2013 with Windows IoT SDK (Visit: windowsondevices.com for more details) and Microsoft IoT C++ SDK and its dependent NuGet Package is required.
