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 :

• uPLibrary : .Net Micro Framework Helper Library;
• M2Mqtt : communication MQTT Client Library;
• .Net Micro Framework Weather Station;

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

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) ...

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!
