M2Mqtt client : a "small" but useful update

I have made a "small" update on my MQTT client (now at version 1.1.0.0), 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 test.mosquitto.org.

   1: public static void Main()
   2: {
   3:     MqttClient client = new MqttClient("test.mosquitto.org");
   4:     ...
   5:     ...
   6: }

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 !

channel9m2m_thumb[2]

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.

My CodePlex projects : upgrade to .Net Micro Framework 4.3

I let it go longer than expected but finally I did ... as they say ... better late than never!

All my projects on CodePlex have been updated to support the latest versions of. NET Micro Framework, the 4.2 and 4.3, but above all Visual Studio 2012!

I’m speaking about :

I hope I have done something pleasing for those who have used them until now.

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

m2mqttpng_thumb

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!

μPLibrary ThingSpeak client on Channel9 !

IoTChannel9_thumb[1]_thumb

This time on Channel9 there is the project of Duke Nukem gas sensoring with .Net Gadgeteer that makes use of my client ThingSpeak included in uPLibrary. I'm obviously happy to see that my "little" work can always be helpful to others and to be recognized as valid and working .... hopefully!
Should serve you, remember that it is always available on NuGet!

Netduino Plus Weather Station !

cloudybar_thumb[4]

I’m pleased to introduce you my new open source project on CodePlex…..Net Micro Framework Weather Station !

This project helps you to build a weather station based on .Net Micro Framework. The data come from some sensors (temperature, humidity, luminosity and wind speed) and you can read them, in real time, using a Web page on the integrated Web Server. Enabling data logging, you can save your data into a microSD.

Img1_thumb[2]

The project is built for Netduino Plus board and based on .Net Micro Framework 4.2 but you can use a different board changing only the pin for the sensors connections.

It uses Metro UI CSS (http://metroui.org.ua/) for Metro style Web page.

Gas sensoring project with my ThingSpeak client into uPLibrary

I’m pleased to know that my library uPLibrary has become one of the most downloaded in the NuGet. for Net Micro Framework, but that is mainly used for projects that are useful and real.
In fact, the client ThingSpeak I have integrated in the latest version was used in this project of gas sensoring on TinyCLR, using the platform. Net Gadgeteer. It 'also a video on YouTube with the demo and was made ​​public on ThingSpeak channel that shows the real-time measurements.
