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…

Integration PLC Panasonic Device Types – Bulk upload devices with Ubidots

En In this opportunity we will carry out tests with a Programmable Logic Controller, in this case a PLC FP-X C14R compact Panasonic brand, we will control it from the IoT Ubidots platform.
