This video is around the FiPy module from Pycom which comes with ESP32 controller and supports 5 network communication protocol support on a single board. The protocols include LoRa/Sigfox/LTE CAT M1/Bluetooth and Wi-Fi. There are radios available for LoRa and LTE whereas the ESp32 itself supports Wi-Fi and Bluetooth. Pycom supports programming the modules using micropython and there are plugins available for VS Code and Atom editor. They also provide easy to use APIs to access the module using ...
This video is a demonstration of the Firmata protocol application with MT7688 MPU and Atmega32u4 MCU with Arduino bootloader. The DHT12 sensor is connected to the I2C interface of the Atmega32u4 MCU and the MPU fetches the sensor data from the MCU using Firmata protocol. Then the MPU which is running OpenWRT publishes the data from the sensor to an MQTT topic. All the scripts executing in the MPU are written in Python.       Relavent Links: Codes and Schematics (Github Reposit ...
