Real-time Location based Bluetooth MESH with PUB/SUB Two-way Communication
Jung-Tang Huang, Shun-Min Lin · 2023
Due to the needs of automation in today's industrial environment, the demand for the Internet of Things is increasing. Here, we use an innovative location-based Bluetooth MESH to provide the IoT MESH system in the factory or at home, and use the Bluetooth broadcaster function as the main wireless transmission of the network. By receiving the acknowledgement packet and the positions of the relay nodes, it provides a first-in, first-out Queue and a Fast-Scan routing method for the transmission algorithm, which can achieve one-to-one and many-to-many routing. Multiple PUB/SUB two-way communication can be transmitted through the cloud as the center or decentralized. Basically, the BLE nodes in the field can communicate with each other, and the transmission delay is in the range of tens to hundreds of milliseconds. It can monitor the physiological condition of the wearable device on the mobile users, and can also control the position of personnel, and can graft the wired sensor already installed in the factory into our BLE MESH system. One example realized is to connect the Modbus communication to our system, and in the future LE audio can also come into our system when it is officially launched on the market
