M2Mqtt client : a "small" but useful update

I have made a "small" update on my MQTT client (now at version, adding an additional constructor on MqttClient class which has the host name of the broker as parameter (adding to the constructor that provides only the address IP). Such a constructor may be useful in all those cases in which you use a MQTT public broker , such as the Mosquitto test server that is at

   2: {
   3:     MqttClient client = new MqttClient("");

uCloudy : access to the cloud. NET Micro Framework is served!

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 ...

A micro HTTP client inside uPLibrary !

I never stop and even now that I'm on vacation I still .... develop! This time it's up to my uPLibrary I upgraded to version 2.0 (of course also on Nuget with support for three versions of the. NET Micro Framework 4.1 from 4.1 to the current 4.3) with a new component: an HTTP client. All you're probably asking questions about why the need to rewrite an HTTP client whereas there are already thoroughly tested the HttpWebRequest and HttpWebResponse directly included. Net Micro Framework. The reason is that in some boards with low memory (see Netduino), the assemblies for these two classes are too large and working with streams they are under-performing. For this reason, I decided to create a simple client (any advice for its improvement is welcome) that uses directly the socket without any intermediate layer of abstraction (a concept that many times in embedded systems must be limited to improve performance). The programming model is quite simple, as it involves the use of the HttpClient class that provides t ...

My M2Mqtt library on Channel9 !


The MQTT client, which I released on CodePlex that can be used with all versions of the. Net Framework specially with NET Micro Framework, was published with a blog post on Coding4Fun on Channel9 by Greg Duncan.

.Net Micro Framework on your wrist ? AGENT smart watch !

From the Secret Labs (makers of the family of Netduino board), a very interesting project funded through Kickstarter: AGENT smart watch, a watch "intelligent" completely based on. NET Micro Framework! The initial goal of $ 100,000 has been largely superseded even share reaching $ 1 million! Ten times higher than the target set! But what this product promises, whose distribution will begin at the end of 2013 for all those who have participated in the financing (the "backers")? Managed Runtime As anticipated, the AGENT is completely based on. NET Micro Framework (version 4.3) with all those who are the advantages for developers in managed code (eg C #), but mainly related to the development environment that is obviously Visual Studio 2012 ! Hardware : double processor, LCD and sensors Since applications developed for the smart watch may require more power, the AGENT has a Cortex-M4 to 120 Mhz to which, however, was accompanied by a second processor (an AVR, much reduced) in such a way that the primar ...

MQTT and .Net Micro Framework with Netduino Plus board : a simple alarm system !

Since I loaded my small MQTT client. Net Framework (Desktop, Compact and Micro) on CodePlex, I have never posted a simple example of the use of time for questions. In this post, we shall see how it is possible to realize a "simple" alarm system consists of two boards Netduino Plus both connected in the network, through the first board we are able to detect a movement through the use of a PIR (Passive InfraRed) sensor while the second is capable of receiving the notification of the detection (in this case does is to write it on the console Debug). Obviously, the second board may be trivially replaced by a smartphone through which we could be alerted in real time of the intrusion. Regarding the broker, it is the simple RSMB (Really Small Message Broker) of IBM which can be used in a totally free for non-commercial purposes and downloaded here. You do not need to install it but, in the case of Windows, is a simple executable to be launched in order to have a broker and MQTT listening on the default port (1883) ...

One of my new little project on CodePlex: M2Mqtt


I have just posted a new little CodePlex project: M2Mqtt.

It is a MQTT client (Message Queue Telemetry Transport) that can be used on all .Net platforms, obviously focused on. NET Micro Framework.

MQTT is a protocol for M2M (Machine to Machine) as part of the Internet of Things and for which lately has been a process of standardization by OASIS. Suffice it to say that thanks to his remarkable "lightness", was chosen as the protocol for the exchange of messages through the Facebook Messenger.

For further information please refer to the official website MQTT but I will not fail to publish as soon as possible a series of articles related to this protocol and to the use of the library that I just released.

I recommend .... stay tuned!

The Net MF weather station on Channel9!


The project on the weather station that I have already published on CodePlex is the subject of one of the blog posts Coding4Fun on Channel9, as always managed by Greg Duncan.

Netduino 2: also the younger brother of Plus enhances !

It just been officially announced on the Netduino forum the release of the new version of the base of the SecretLabs boards : the Netduino 2 ! After the release of the second version of the board that has Ethernet connectivity and microSD onboard, the Netduino Plus 2, the entry-level version board has a successor even more powerful. Microprocessor and memory Following the same line of Netduino Plus 2, the microprocessor is completely different from that of its predecessor, in fact it is a STM32F2 (from STMicroelectronics) based on architecture Cortex-M3 to 120MHz in place of an Atmel ARM7 to 48 Mhz. The jump of memory is amazing! The amount of available RAM is 60 KB and for Flash the amount available to our application goes from 128 to 192 KB. Input and Output The board provides 22 GPIO pins (compared to 20 above), part of which have the following features: 6 PWM; 4 UART; SPI interface; I2C interface; In addition, there are 6-channel ADC with a resolution of 12 bits (rather tha ...

μPLibrary on Channel 9 !


uPLibrary, dedicated to. NET Micro Framework, which I started developing for over a year and upgrade over time with new features has been reported on Channel 9 in Blog Coding4Fun thanks to the efforts of Greg Duncan at the following link.
