Abstract
Con el avance y el auge de Internet de las Cosas (IoT), las redes con topología en malla se han convertido en una solución popular, puesto que permiten la interconexión entre cientos, e incluso miles, de dispositivos IoT, los cuales han crecido de manera exponencial estos últimos años.
Hoy en día ya existen algunas tecnologías de comunicación inalámbrica exitosas que implementan dicha topología de red y que utilizan dispositivos de bajo coste y de bajo consumo. Bluetooth Low Energy ha sido históricamente una solución ampliamente aceptada dentro del mundo IoT debido a sus características. Con la incorporación de Bluetooth Mesh, que introduce la capacidad de desplegar topologías en malla en base a Bluetooth Low Energy, este protocolo se acerca a soluciones IoT a gran escala como, por ejemplo, automatización de edificios, redes de sensores, iluminación inteligente, etc.
Este documento pretende ser una guía para que el lector profundice en la tecnología Bluetooth Mesh, pues aparecen conceptos nuevos con respecto a Bluetooth LE, como, por ejemplo, proceso de aprovisionamiento, nodos, elementos, modelos, clave de aplicación, clave de red, etc.
Por otro lado, hay que tener en cuenta que el mercado ha evolucionado de la mano de esta novedosa tecnología, por lo que empresas líderes en el sector IoT han creado kits de desarrollo para implementar Bluetooth Mesh. En este caso, se hace uso de ESP-IDF, un framework desarrollado por la compañía Espressif Systems, que ayudará a implementar dos pruebas de concepto que muestren el funcionamiento de la malla Bluetooth a través de la configuración de múltiples modelos.
With the advancement and rise of the Internet of Things (IoT), mesh topology networks have become a popular solution, as they allow the interconnection between hundreds, and even thousands, of IoT devices, which have grown exponentially in recent years. As of today, there are already some successful wireless communication technologies that implement such a network topology that use low-cost and lowpower devices. Bluetooth Low Energy has historically been a widely accepted solution within the IoT world due to its characteristics. With the incorporation of Bluetooth Mesh, which introduces the ability to deploy mesh topologies based on Bluetooth Low Energy, this protocol approaches large-scale IoT solutions such as, for example, building automation, sensor networks, intelligent lighting, etc. This document is intended to be a guide for the reader to delve into Bluetooth Mesh technology, as new concepts appear regarding Bluetooth LE, such as, for example, provisioning process, nodes, elements, models, application key, network key, etc. On the other hand, it must be taken into account that the market has evolved hand in hand with this new technology, which is why leading companies in the IoT sector have created development kits to implement Bluetooth Mesh. In this case, use is made of ESP-IDF, a framework developed by the company Espressif Systems, which will help implement two proofs of concept that show the operation of the Bluetooth mesh through the configuration of multiple models.
