This article is not intended to be an introduction or full guide on Node-RED but it will describe how we can run it in the cloud ! Thanks to its NodeJS base and the power of all services provided by Microsoft Azure, you can create an Azure Web Site for a NodeJS application that can host Node-RED so that you can access, control and develop on it from everywhere !
In this way, we don’t need to s ...

The M2Mqtt library is now at 220.127.116.11 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
6: Error = 0x01,
7: Warning = 0x02,
8: Information = 0x04,
9: Verbose = 0x0F,
10: Frame = 0x10
A simple example of tracing usage could be the following :
1: Trace.TraceLevel = MqttUtility.TraceLevel.Verbose | MqttUtility.TraceLevel.Frame;
2: Trace.T ...
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 ! ...
This year, I will have the great pleasure and honor of being speaker at the only one educational Italian conference on embedded world, Better Embedded 2014, which will take place on 4 and 5 July in Florence at the Hotel Londra.
My session will be focused on the Internet of Things with a look at "war" between the main protocols used for it, such as HTTP (REST), AMQP, MQTT and CoAP (I'll add XMPP and DDS as soon as possibile after deep into them). The comparison between them will be literally on the field, so no more an introduction to the protocols themselves but more battles on different fields in which each protocol will try to get the better on the others.
There will be a winner ? To find out, you just need to subscribe to the event and come to follow my session !
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 TinyCLR.it 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.
