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

• Supported for both Intel Galileo Gen1 and Gen2.
• Latest OS update released (A 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.
• As explained in Windows IoT on Galileo – Using Event Hubs (Connectthedot.io) , Download the sample Event hub source code given for Galileo from github.

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”.

https://github.com/MSOpenTech/connectthedots/tree/master/Devices/DirectlyConnectedDevices/IntelGalileo

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 – Sensors to Server Part-2

As a final touch and the continuation of earlier Windows IoT for Galileo – Sensors to Server, This blog explain you on how to retrieve sensor data from Azure storage table services that already have sensor data pushed from Galileo Windows IoT.

      Prerequisites

• Visual studio 2013 with Windows phone 8.1 SDK.
•  NuGet package for Windows Azure Storage services version 4.3.0 and its dependencies.

Windows IoT on Galileo – Sensors to Server

This blog explain you on how to push data to Azure storage table services from Adafruit 10-DOF IMU sensor module connected to Galileo Gen1 or Gen2.  

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.
• http://ms-iot.github.io/content/Casablanca.htm
• NuGet package for Microsoft Azure Storage Client Library for C++ 0.3.0-preview
• Source code for Azure Storage Client Library for C++ 0.3.0-preview from Github.
• Sample source code to access the Azure storage client library. I used the source code for accessing table for this example but it should work for all storage services.

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!!!

This blog explain you on how to connect the Adafruit 10DOF IMU (A combo board provides 3-axis gyro, 3-axis compass, barometric pressure and temperature sensors) to Galileo Gen 1 board using Windows IoT. I bought this sensor board for some other purpose but I found it is also Arduino compatible, so I tried with Galileo and succeeded.

Windows Embedded Compact – Accessing Microsoft Azure Storage services

Microsoft Azure storage services contains queues, tables and blob storage. This table is a non SQL tables which store data in a simple manner and it has its unique advantage than the Azure SQL Database in cost aspect.
There is no standard library so far to access Azure storage services in Windows Embedded compact. Accessing storage services requires HTTP REST API implementation, e-con systems has developed a .Net CF based framework to access Azure storage services from Windows Embedded Compact.

Windows IoT on Galileo – The Beginning

As many of you know Microsoft is focusing on Internet of Things (IoT) and it has started developing an IoT version of Windows OS. It was announced in the Build 2014 conference. As a first step, Microsoft open a Web site and encourage developers (Professionals, Students and Hobbyist) to register here in order to receive a worthy Intel Galileo development kit with Windows IoT on it. You can see more information about Windows Developer Program for IoT in the below link.
http://dev.windows.com/en-us/featured/Windows-Developer-Program-for-IoT

As a Microsoft MVP, I am privileged to receive the earlier shipment of Galileo kit. Thanks to Windows Embedded (IoT) team. Many of the registered developers will receive this package soon.
