Virtualization is one of the most used methods to facilitate the compatibility of Software or simply the test of other Operating Systems, technically it is an operating system within another. I have tried for a long time Oracle VirtualBox is one of the most used virtualization software for x86 / amd64 architectures allowing virtualization. FreeBSD…

MQTT
Is an ISO standard (ISO / IEC 20922 PRF) publication-subscription-based “lightweight” messaging protocol for use at the top of the TCP / IP protocol. It is designed for connections to remote locations where a “small footprint” or limited bandwidth is required.

We have compiled Information regarding the MQTT Protocol making integrations with other devices and platforms:
Introduction to mDash platform for administration of IoT Devices
On this occasion I present the platform or an administration service for IoT devices called mDash, belonging to Cesanta, the creators of the IoT Mongoose Os development firmware. mDash allows firmware updates OTA (over-the-air) and remote administration, alerts and notifications, remote device control, file management with devices, all these features are for Espressif’s modules ESP32…
MQTT in ESP32 with ESP-IDF – ESP-MQTT & Node-RED
Normally if we look for tests with the ESP32 module and the MQTT protocol, they mainly use Arduino IDE for ESP32, there is no problem, but this time we will use espressif development environment “ESP-IDF” or “Espressif IoT Development Framework” for the ESP32 which has more advantages and features for more robust applications. ESP32 Module…
ESP8266 & Public MQTT Broker mosquitto.org & Node-RED
In the last tests we have taken the MQTT protocol since it has taken great strength the last few years and we think it is thanks to its simplicity, security, practicality and very lightweight projects IoT and M2M applications. Thanks to the contribution of developers and developers of MQTT applications, there are public MQTT Internet…
ESP8266 & Public Broker MQTT mosca.io & Node-RED
The MQTT protocol has taken great strength in recent years since it is simple, safe, practical and lightweight perfect for IoT and M2M applications. Thanks to the contribution of developers and developers of MQTT applications, there are public MQTT Broker for tests, are available to connect from any MQTT client in this case will use…
ESP8266 & Public MQTT Broker HiveMQ & Node-RED
The MQTT protocol has taken great strength in recent years since it is simple, safe, practical and lightweight perfect for IoT and M2M applications. Thanks to the contribution of developers and developers of MQTT applications, there are public MQTT Broker for Internet monitoring and control tests, are available to connect from any MQTT client in…
Tutorial ESP8266 Node-RED Granafa InfluxDB MQTT
Based on the previous instructions of the ESP8266 connection with the Node-RED implementing the mqtt protocol, we have performed tests of the connection of several software platforms for the collection and visualization of data. We consider these 2 Grafana and InfluxDB for development and Interactive From the internet of things. Install Node-RED Installation Node red Platform…
Tutorial Amplifier Audio PAM8302A ESP8266 Node-RED MQTT
There is a great variety of arduino tutorials generating melodies, one of the most common the famous “Imperial March” of the well-known Star Wars movie, I downloaded one of the examples for Arduino I made several modifications to work on an ESP8266 01 and I have included An audio amplifier to this test. We have also…
Tutorial ESP8266 DS18B20 Temperature Node-RED MQTT (Mosquitto) IoT
This time the integration of ESP8266 and the Node-RED platform was realized integrating a sensor DS18B20 of Protocol of Temperature Onewire. From an HMI or SCADA Web creator on Node-Red-Dashboard using the MQTT protocol and the pubsubclient library converting the ESP8266 into the MQTT Client will perform the sensor reading periodically. Video Test ESP8266 Temperature DS18B20…
Tutorial ESP8266 Control Servo Node-RED MQTT (Mosquitto) IoT #2
This time the integration of ESP8266 and the Node-RED platform has been made integrating an actuator in this case a servo controlled by PWM with rotation from 0 to 180 degrees. From an HMI or SCADA Web creator on Node-Red-Dashboard using as base the MQTT Protocol and pubsubclient library converting the ESP8266 into MQTT Client….
