I remember when I heard about it in the college... Now it is happening. The problem I see that if I want to create applications using things I will have to get in the middle of the chaos that is happening right now. Of course, in the software side there're great initiatives, such as RHIOT  and MQTT , but in the hardware side, well, I bought a lot of sensors, devices and I always have to spend some time with it to actually start creating applications.. Then I found the IoT Surfboard project. About IoTSurfboard The project leader is the java champion Vinicius Senger and it is aimed to allow from beginners to experts to create IoT applications. It is a board that is based on Arduino and comes with components and sensors already integrated: IoTSurfboard components The good thing is th...

First steps with MQTT using Mosquitto

In this post I will quickly show the steps I followed to install and test mosquitto , a MQTT server . Installing and starting Mosquitto In my case I simply added the yum repository and then, as root, I run yum install mosquitto . After a few minutes it was installed. To install it for your system, please see mosquitto download page . After the installation, you can run mosquitto in the command line and the server will be started: Running mosquitto. You can also run in daemon mode, see the mosquitto man page for further information To test the installation I suggest to install the mosquito clients: yum install mosquitto-clients.x86_64. Once you install the clients, let's use the mosquito_sub tool to subscribe to the topic fxapps/test: Subscribing to the topic fxapps/test. The -q parameter sets the QoS. For further information see mosquitto_pub man page .   Now we are able to public strings to it using mosquito_pub : Publishing a message to the topi...
