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 !
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.
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 ...
With a week later than the expected output, I finally released in Beta an MQTT broker completely developed in C# that can run on .NET Framework and .NET Compact Framework 3.9 (on systems with Windows Embedded Compact 2013) his name is ... GnatMQ !
It has the M2Mqtt library “core” with which it shares the features of MQTT protocol about the part of the connection to the clients and the messages management.
Obviously, it is completely open source and available on CodePlex but is currently in Beta version (aspect numerous reports on your part!).
Main features included in the current release :
All three Quality of Service (QoS) Levels (at most once, at least once, exactly once);
Will message (QoS, topic and message);
Username/Password via a User Access Control;
Subscription to topics with wildcards;
Publish and subscribe handle using inf ...
Today is "born" a new dedicated website by Microsoft on the Internet of Things that talks about the Internet of Your Things and highlights that the IoT can be achieved by each of us with his own "things" that can interconnect with each other through the Cloud.
On the website you can find all the information about this new (or already mature ?) project on which Microsoft is focusing its business using what is already good for the embedded world (all operating systems of the Windows Embedded family to which I would add the .NET Micro Framework) and joining it to the powerful of the Cloud (Microsoft Azure is well known).
It's true what the new CEO Satya Nadella said with intention to want "a cloud for everyone , on every device" for which the #cloud4device can be understood in its most general main, not only smartphones and tablets but also devices and "things" that connect to the big network !
You can subscribe to a newsletter that will begin on July 1st, but ... maybe from that date ... we'll see ...
On Saturday 15th of February was staged the second edition of Microsoft Embedded Conference which was held at the Holiday Inn in Naples and organized by the DotNetCampania community (I am a member of it), TinyCLR.it and Embedded101, this community that is a reference on Windows Embedded of which, I’m a "board of directors" member since November 2013.
Also this year there was a good turnout of attendees even though it was Saturday, because the main topic was the Internet of Things and M2M Communication of which we hear persistently in the last period as the business of the future for the big network.
At 8:00, the team was ready for the preparations and organization in order to accommodate very well the attendees and ensure that the event will start on time. As with all events, we started with the keynote of our president Michele Aponte, who presented the community and to whom I have given ...
I have just updated on CodePlex and Nuget my uPLibrary library (version 18.104.22.168), adding automatic detection of any IPv6 address to the HTTP client (HttpClient class) .
To determine the address class (AddressFamily), I implemented the '"Extension Method" GetAddressFamily () for the IPAddress class through the static class IPAddressUtility, needed only because the. NET Micro Framework does not itself provide the property AddressFamily in the IPAddress class.
1: public static AddressFamily GetAddressFamily(this IPAddress ipAddress)
3: return (ipAddress.ToString().IndexOf(':') != -1) ?
4: AddressFamily.InterNetworkV6 : AddressFamily.InterNetwork;
In this way, at the time of the creation of the socket, it is automatically set to the correct address family from the address to connect to.
1: // create socket and connect
2: this.socket = new Socket(
4: Sock ...
This is the time of a project completely dedicated to Cloud but always with the goal of providing additional functionality and capabilities to an embedded system.
uCloudy is a library that aims to provide a variety of clients for. NET Micro Framework to connect to the main cloud services. The first and for now only service supported in this first release is Windows Azure Mobile Services.
As we all know, Microsoft provides a set of SDK to take advantage of this service in Windows applications store, Windows Phone, iOS, Android and the Web I have tried to bring this functionality in embedded systems with. NET Micro Framework. All this has been made possible thanks to the RESTful interface that the mobile services provide for interfacing to them. Thanks to the HTTP client that I recently integrated into uPLibrary, I made a series of classes through which you can perform the four basic operations on the tables of mobile services: insert, update, delete, and query.
The client is implemented through th ...
