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…

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…

Review Module Wemos TTGO ESP32 + OLED V2.0 + DHT11

I present a TTGO ESP32 module, this device has caught my attention since it is very complete, I ordered one to the Banggood.com online store for testing, the interesting thing is the union of the well known ESP32 module, DHT11 Sensor (Temperature / Relative Humidity ), 0.96 inch white OLED display, charging circuit for Lithium…

ESP-IDF for Modules ESP32 Complete Installation

This time we will install and configure  Espressif IoT Development Framework platform (ESP-IDF) from scratch, this is the official espressif development platform for the ESP32 modules. In previous tutorials we talked a little about the ESP32 that have Wi-Fi (2.4 GHz band) and Bluetooth 4.2 in a single module among other features. ESP32 eBox&Widora first review I took…
