New release for my M2Mqtt library, MQTT client available for any platform based on .Net Framework (from the desktop to the micro via the compact), now at version 2.4.0.0 and as always is available on CodePlex and Nuget. Bug Fix : message identifier no longer cross-broker This time the update contains, among other things, an important bug fixes on the message identifier generation for PUBLISH, SUBSCRIBE and UNSUBSCRIBE messages provided by the MQTT protocol. In previous versions, the generation of this identifier was encapsulated in the base class of the hierarchy of messages, the MqttMsgBase, highlighting the anomaly of a message identifier increasing cross-broker, which was used the same variable (static) for the generation also if the client was instantiated multiple times in our application to connect to multiple different brokers. Obviously, the protocol provides that the identifier is bound to the client-broker pair, namely that it is unique for each connection to the broker. .Net Compact Framework 3 ...

This time again with great pleasure, my M2Mqtt library (MQTT client for all versions of the. Net Framework) is mentioned in the "fardware friday post" on the blog Coding4Fun on Channel9 at the following link !

The post highlights the main latest features, support for security through SSL / TLS protocol and event management asynchronously. It is also highlighted my demo on the use of the MQTT client with 2lemetry platform.

The satisfaction is double in knowing that my work is attracting a lot of interest and that the library is increasingly being used. Obviously, this leads me to improve it and in fact approaching many surprises and improvements!

On the horizon there are some good news for the future of .Net Micro Framework ! It 's been a year (exactly December 4, 2012) since it was first released version 4.3 RTM and any updates since then .... until the last few days! On the official forum of Netduino platform, Chris Walker (Secret Labs) responded on the lack of platform update with the following words: I sat down with the program manager for NETMF in Seattle two weeks ago, to discuss progress on NETMF 4.3 QFE1. QFE1 is getting closer; we're all pretty excited to move over the NETMF 4.3 core. Speaking of 4.3...we have a few surprises in store, once NETMF 4.3 QFE1 ships. We've been busy this year, especially in the software department. Quite a few community members have been contributing behind the scenes too. We should have lots of love and kudos to share in the near future. Chris obviously has participated at MVP Summit in November 2013, along with all other MVPs and with the development team on. Net Micro Framework. It se ...

Now you can find numerous online platforms that offer the service of "device to the cloud," in order to acquire data from remote devices, save and expose them to other devices: one of these is 2lemetry. It provides a RESTful interface over HTTP and an MQTT interface that we are going to use with the M2Mqtt client library. First you need to register online : At the end of the registration, you can log in to your account page and view some information, including the most important one is the "domain", which will be the root of all topics on which we are going to publish or receive messages via MQTT. At this point we can move immediately to develop a simple application by choosing between all platforms supported by the M2Mqtt library (.NET Framework, .Net Compact Framework or. Net Micro Framework). In a real case, we use the Netduino Plus board with a temperature sensor (usually the TMP102 already widely used in previous posts and where the driver can be found in uPLibrary) to send the data collected onlin ...

The Platform Builder build system is quite complicated but at the same time extremely powerful. In order to save valuable time during the compilation of our operating system image, it is necessary to know it in details so that we can avoid unnecessary operations. In addition, there are a number of "tricks" that allow us to make it much faster. Among these, there is the possibility to leverage the compilation on more "core" of our CPU, whereas all modern PCs have now from 2 "core" up. The key of this possibility is the environment variable BUILD_MULTIPROCESSOR, whose meaning can be interpreted in the wrong way if you do not carefully read the documentation. Mistakenly, you might think that setting it to 0, the compilation on more "core" is disabled and vice versa activated by setting it to 1. It is not so! Referring to the documentation on MSDN,, if you set the value to 0 you will let the system to automatically detect the number of "core" of the CPU and use all for the compilation by creating an appropriate ...
