BL .E Mesh solution

BLE mesh indoor positioning solution, which uses BLE nodes with Bluetooth mesh networking function for networking to form a positioning-orientedBluetooth mesh grid system that can scan BLE devices within the area and form a location information database. Mobile devices can access thecommunication stability is greatly improved. At the same time, due to the distributed setting of each Bluetooth device，The problem of signal .mesh network without a central node, each node can relay and send data, which realizes network communication. By controlling the data flow, thecommunication stability is greatly improved. At the same time, due to the distributed setting of each Bluetooth device，The problem of signal .occlusion is solved, and a very high positioning accuracy can be achieved by designing an appropriate setting interval. On the basis of indoorpositioning, vital signs data such as heart rate, step count, exercise volume, etc. can be obtained at the same time, and environmental sensor data such as temperature and humidity can also be obtained at the same time.
