Modificación del firmware del módulo ESP8266 para construir un dispositivo On – Off que será comandado por una aplicación residente en un dispositivo Android en una red Wlan.

Abstract

The purpose of this degree project is to modify the software of the ESP8266 module, to design and build an ON – OFF device, taking advantage of the Arduino platform software, commanded by a resident application on the Android operating system within a WLAN network. The procedure focuses on four important processes, firstly, a power supply is designed for the ESP8266 module, which works with 3.3Vdc, through a 5 Vdc source, from the general voltage line of 110 /220 Vac. The second process is to modify the module software, from its original, based on AT commands to the Arduino command system. Thirdly, the ESP8266 module is programmed, using Arduino, as a WEB server, which works on a wireless network. The fourth step is to design a resident application for Android, which serves as an interface between the user and the ON – OFF control device. The final result is the implementation of the designed device achieving the project objective.
