Now … I can write something !!
About two weeks ago I received a great present from Secret Labs (thanks to Chris Walker) … the new Netduino 3 Wi-Fi board !
This time, with great honor, I will be among the speakers of the Community Days 2014 to be held September 23 to 25 in Rome, after I was there more times as attendee in the past.
The honor will be double, because I will have the session with my dear friend Valter Minute that I recognized as the "Maradona" of embedded systems.
Our session entitled "Internet of Things: my washing machine connected to the Internet?" will be completely dedicated to IoT starting from embedded systems (Microsoft based) to the possible solutions in the Cloud, including the future project "Reykjavik" based on Azure and presented at Build 2014; the title tells the truth, among other things, we will have as its protagonist a washing machine (toy) !
You can find all the information concerning the agenda of the sessions and logistics on the official website in addition to the registration form.
We look forward to this event every year will not disappoint the expectations of those who participate !
After I wrote the article about the Node-RED installation with a Web Site in Microsoft Azure, I decided to start another "small" open source project closely related to the "flow-based programming" with Node-RED using the Microsoft Azure services.
Starting from Azure SDK for Node.js I am asked myself the following question: why not make available to the Node-RED users all the Microsoft Azure services in their "flows" ?
From there I had a new project idea : Azure Nodes !
This project, available on GitHub, adds a bunch of nodes ("azure" colored) to the Node-RED toolbox through which you can interact with the Microsoft Azure services. The current version is still in Beta and it supports only the Service Bus features (queue and topic / subscription) very useful in the Internet of Things, I love.
The documentation is available in the Wiki pages related to the project even if the use of the nodes is remarkably simple and intuitive.
There are still many (too much ?) debug messages displayed ...
This article is not intended to be an introduction or full guide on Node-RED but it will describe how we can run it in the cloud ! Thanks to its NodeJS base and the power of all services provided by Microsoft Azure, you can create an Azure Web Site for a NodeJS application that can host Node-RED so that you can access, control and develop on it from everywhere !
In this way, we don’t need to s ...
Friday, June 6th IoT@Work event was held in Rome at the Microsoft headquarters and it was organized by the DomusDotNet community and the online TinyCLR.it community (of which I am member).
Thanks to the hospitality of Massimo Bonanni and all the guys in the community, we spent an entire day dedicated to the Internet of Things.
In the morning, Mirco Vanini started showing us what Internet of Things is and what it is not with a series of real use cases and future projections of this new business. The next session saw myself as the lead in tackling a technical point of view of main protocols that are used in the IoT, each with their own advantages and disadvantages. The morning sessions were completed by Lorenzo Maiorfi who spoke of "flow-programming", its application in the IoT and two main tools that can be used for this purpose: NodeRed and Orleans.
A new case study for M2Mqtt project and this time with a demo at one of the most important event in the United States, Visual Studio Live !
Rick G. Garibay, Microsoft Azure MVP, was speaker at the Visual Studio Live event in Chicago with two interesting sessions including one dedicated to IoT with Microsoft Azure and entitled “From the Internet of Things to Intelligent Systems – A developer’s primer”.
Rick has made a very interesting demo with Azure Device Gateway (also known as Reykjavik project) of which we have already heard at Build 2014; thanks to it we can connect multiple devices, through different protocols, in the Azure IoT world.
Regarding the devices, the demo had an Arduino board and a Netduino Plus 2 board, connected to a RabbitMQ broker via the MQTT protocol. Obviously, the part relating to the .NET Micro Framework used the M2Mqtt library !
You can find all the materials related to this session on the official blog of Rick at the following link, the ...
In this post, we'll see how easy it is to execute GnatMQ, the MQTT broker for .NET Framework, in the Cloud using the Microsoft Azure platform. The execution of the broker can be started through a Worker Role that is one of the "Cloud Services" offered by Microsoft.
Create the Cloud Service
In the "Server Explorer", click with the right button on "Windows Azure" and "Connect to Windows Azure ..." and execute login using our Azure credentials(the ones we use in the online management portal).
The "Server Explorer" refreshes and displays all the "Windows Azure" services currently active with our account (Cloud Services for web role and worker role, Service Bus with its namespaces, Virtual Machines and so on).
Since our goal is to execute the GnatMQ broker in a worker role, we need to create a new "Cloud Services", right-clicking on it and selecting "Create Cloud Service ...". Select the subscription you want to associate the new service, the name and the region where it will be executed.
The creation o ...
In the course of this tutorial we will see how it is possible to use the Raspberry Pi as a AMQP (Advanced Message Queuing Protocol) client and connect it to Windows Azure Service Bus that supports the AMQP version 1.0.
Obviously, the choice of the client library is almost forced : Apache Qpid Proton. This library developed in C still provides the bindings for other languages including Java, Python, and PHP but in the course of the article we will use only the native version.
Generally, the Raspberry Pi is used with the Raspbian (based on Debian) distribution which is a Linux distribution. This means that we can install the Qpid Proton library as we do on a normal Ubuntu distribution on a PC or on a virtual machine on Windows Azure.
Connect to the Raspberry Pi
All of the following operations can be performed by directly accessing the Raspberry Pi through a monitor, keyboard, and mouse connected to it or remotely through the use of SSH connection.
The latter solution is certainly the most convenient, usi ...
As a further confirmation that Microsoft wants to be part of the business of the Internet of Things, was released a "limited preview" of a new product on Azure: Azure Microsoft Intelligent System Service.
The primary objective is to provide a single platform capable of acquiring data generated by heterogeneous systems (and thus non-Microsoft) for further processing and analyzing in real-time with tools like HDInsight.
The main features will be :
Connectivity : ability to connect any device regardless of onboard operating system;
Configuration : definition of rules to automate processes on the device;
Administration : ability to monitor, configure and update devices in the field;
Extensibility : greater scalability and efficiency through infrastructure based on cloud;
At the following link, it is possible to request a limited preview to which potential users will have access as a result of a questionnaire for assessing the project to ...
One of the protocols most commonly used in the messaging systems that can be also used for the Internet of Things is the AMQP (Advanced Message Queuing Protocol) that already is OASIS standard and now it is at version 1.0.
The Service Bus offered by Windows Azure supports this protocol, that ensures communication between clients developed on different platforms. In the case of a Microsoft platform we have no problem thanks to the Windows Azure SDK (now at version 2.3) that completely abstracts the underlying communication protocol with the Service Bus (AMQP, SBMP, ...) thanks to its programming model.
if we are working on a non-Microsoft system, one of the best choices is to adopt the libraries of the Apache Qpid project and in particular the Qpid Proton. This library is developed in C and it provides the bindings for other languages including Java, Python, and PHP.
In this tutorial, we will see how to create an Ubuntu Server 12.04 LTS virtual machine on Windows Azure, install and use the Qpid Pr ...
