.Net Micro Framework : 4.3 SDK R2 Beta released with Visual Studio 2013 support and new look for the official web site !

News, news … news !

The waiting is over ! The first news of the new life of .Net Micro Framework have been announced publicly yesterday with the new SDK R2 Beta release for the 4.3 version.

M2Mqtt and GnatMQ … now on Windows 8.1 and Windows Phone 8.1 !!

      It seems that I was on vacation (given the lack of posts on my blog) and it's the truth ! Despite the holiday, I continued the development of the M2Mqtt project and today I am pleased to release the new version with WinRT support !! I made some changes on networking layer (from Socket to StreamSocket), thread (from Thread to Task) and security but finally the first MQTT client for all .Net platforms today also works on tablets with Windows 8.1 and on smartphones with Windows Phone 8.1. The new project, added in a Visual Studio 2013 solution, is a "portable class library" that I used and tested in a Universal App. The same for the "brother" GnatMQ, now in version (Beta), thanks to which we have an MQTT broker to run on tablet and smartphone with Windows 8.1 OS family. Of course I updated the Nuget package by adding the assemblies for WinRT. I hope I did something useful f ...

M2Mqtt 3.5 : .Net MQTT client with improved SSL/TLS support, other features and Apache 2.0 license !

    This time the M2Mqtt library has undergone some "important" changes in terms of new features and bug fixing. I have to admit that the improvements are mainly due to the people who use it and report me to add new features or bugs to fix. In addition to several issues reported on CodePlex, this time also Clemens Vasters, PM on Microsoft Azure, submitted some improvements to be applied in the context of SSL / TLS authentication. In fact, as already tweeted several weeks ago, Clemens used my library to run tests on the Reykjavik project (Device Gateway) presented at Build in 2014 and I can only be honored. SSL/TLS authentication In this case, the improvement is closely related to the .Net Framework version, since it is the only version to support what has been added. In particular, the MqttClient class makes available other constructors which can provide the following callbacks : RemoteCertificateValidationCallback : allows the user to execute further checks on the validation of the ...

M2Mqtt : added tracing support for the MQTT client

The M2Mqtt library is now at release with the new tracing feature in debugging mode. The project has the new Trace class that exposes the static member TraceListener declared as the following delegate : 1: // delegate for writing trace 2: public delegate void WriteTrace(string format, params object[] args); In this way, it is possibile to chose our preferred tracing mode setting a method to this delegate. Furthermore, it is possibile to set the tracing level using thet static member TraceLevel with the following possible values : 1: /// <summary> 2: /// Tracing levels 3: /// </summary> 4: public enum TraceLevel 5: { 6: Error = 0x01, 7: Warning = 0x02, 8: Information = 0x04, 9: Verbose = 0x0F, 10: Frame = 0x10 11: } A simple example of tracing usage could be the following : 1: Trace.TraceLevel = MqttUtility.TraceLevel.Verbose | MqttUtility.TraceLevel.Frame; 2: Trace.T ...

.Net Micro Framework and Internet of Things : a quick tour on coming news and long term future

            In the last days, I saw some interesting things around the future of .Net Micro Framework … First, a post in the GHI Electronics community forum that speaks about the 2014 plan for .Net Gadgeteer. Gary, GHI employee, says : We have some very exciting news to share with you today. First of all, we have been communicating your feedback to Microsoft and they have been very responsive. We can't share all the details yet but we can tell you that you will be very happy with what Microsoft will announce very soon. There are two main points about it : GHI reported to Microsoft all feedbacks by .Net Micro Framework and Gadgeteer users and I think with the objective to improve the framework; There are more details and news that Microsoft will announce very soon, so in the next days (week ? months ?) we will have new official information about .Net Micro Framework future; Of course … the above are great points ! ...

IoT@Work : Internet of Things event in Microsoft headquarters in Rome

  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 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. ...

M2Mqtt Case Study : MQTT with .Net Gadgeteer platform


Blake McNeill, Microsoft Developer Security MVP, has made ​​a very interesting demo using the MQTT protocol with the .NET Gadgeteer platform !

Blake is one of my main fan that uses very often all the open source libraries that I made on CodePlex. This time, talking about MQTT protocol, he has used the M2Mqtt project !

On the official web site, I have just created a page dedicated to case studies for those who wish to share their experience, hobbistic or professional, with client and GnatMQ broker usage. Just contact me and I'll be happy to set up a page dedicated to your project !

The tutorial is well done and describes all the main features and potential of the protocol as well as highlight the simplicity with which it is possible to integrate and use my MQTT client.

You can’t miss it !


M2Mqtt and GnatMQ : the MQTT project for all .Net platforms has its official website !



Finally, the M2Mqtt project, which includes the client library and the GnatMQ broker, has its official website !

In addition to a dedicated blog, there is a documentation section that currently contains the architecture description of the client library, the main advantages in using it and a simple application example. As for the broker, are the main features implemented and future.

In addition, the download section lists all the link to download the project (CodePlex, Nuget and Microsoft Code Gallery).

My objective is also to add a "case study" section with application examples, hobbistic or professional, and/or demos of those who are using the library and/or the broker. Obviously, anyone who wants to participate can contact through the contact section !

M2Mqtt : release for MQTT client on .Net platform

Development of M2Mqtt library continues .... now reached the version ! This time the new features are related to two requests from people who are using it. First, I added more overloads for Connect() method, because from when I removed the default parameters (for compatibility with older versions of the .Net Framework) I left the more complex constructor that requires all parameters. Many people, not knowing well the MQTT protocol, found themselves in difficulty in deciding what values ​​to pass to lesser known parameters (will message, clean session, ...). A further new feature concerns the client disconnected event (from the MQTT broker) that was requested on the official CodePlex web site. The MqttClient class exposes MqttMsgDisconnected event that is raised when a condition of connection failure with the broker is detected and typically in two cases : when there isn’t network traffic, when client sends the PINGREQ message (relative to the keep-alive) it doesn’t receive ...

Welcome to the Internet of Your Things !!

  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 ...
