Extended Range Evaluation of a BLE Mesh Network for Control Application

with the rise of the Internet of Things (IoT)., wireless mesh networks have gained prominence, and there are already some successful technologies that use low-cost, low-power wireless devices to construct such network topologies. Bluetooth low energy (BLE) has become a recent topic of research in both the Internet and the wireless industry. ABLE wireless mesh network protocol utilizes the broadcasting capability of such wireless transmissions. In this paper, a sample of the BLE mesh network is proposed for smart lighting control and evaluation of the Bluetooth extended range communication. Three nodes for the ESP-32 evaluation board and NRF mesh application for android are used in this sample to provision and configure the BLE mesh nodes. These boards are programmed with the BLE mesh program and the Bluetooth range can be extended by a factor of three according to the node's deployment method. As well as network flexibility and coverage area are increased with more optional lighting control processes.
