Download Lubuntu Virtual Machine (PDAControlMV) IoT in VirtualBox # 1

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…

Basic Modbus RTU Master RS485 Test with ESP32 + XY-K485 + PZEM-016 (without libraries)

In this opportunity we will carry out tests and explanation of the Modbus RTU protocol implemented in ESP32 requesting data from the Single-phase consumption meter PZEM-016. The intent of this tutorial is: 1. Explain in a simple way the creation and operation of an industrial protocol, in this case the Modbus RTU protocol used and…

Review HELTEC Module (WIFI LoRa 32) 915-868Mhz for LoRaWAN #4

I have been collecting information about functional nodes for basic LoRaWAN tests for a while. This time I present the HELTEC LoRa 32 v1 Wifi module, it collects several interesting functions in IoT applications. This node is the integration of an ESP32 and a LoRa Chip SX1276 (868-915Mhz) 0.96 inch Oled screen, usb-serial converter CP2102….

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…
