This repository contains all code, research and other resources related with my Master Final Project in Internet of Things about BLE Mesh. The goal is to create a firmware which can be flashed into a ESP32 dev kit in order to work in a BLE Mesh network using the sensor model. Moreover, in order to provide to the user a way to monitoring and interact with the network, It will be created a CLI and a dashboard.
- espCode: Contains original code from espressif repository
- samples: Some C code that, after testing, have been included into src.
- src: Contains the code developed for this final project. It is splitted into differents folders depends on what piece of the architecture belongs to
- cli: Contains a simple cli to interact with the BLE Mesh network. It is developed in Ruby.
- dashboard: Contains configurations files and a dashboard ready to use. Also, there is a collect_data.rb script but it is not used.
- sensor_client: Contains all the necessary code to build the client firmware.
- sensor_server: Contains all the necessary code to build the server firmware.
Every action is launched by the CLI. These actions are processed and transformed into ble task by the Client so, when a server response the client publish the data to make it available for the Dashboard. The Dashboard is composed by InfluxDB, Telegraf and Grafana.
When a task is received by the client, he processed in MQTT module and send the required info to BLE Cmd module using a queue. BLE Cmd check if a task exists with the name given (with the TaskManager module). If not or if it is a one-time task, then it is launched. When the server response, the client receive the message and give the info to message parser module to build a json. This allow to the MQTT module to publish this information.
