Bluetooth gateway is mainly used to scan Bluetooth devices and iBeacon devices, and then realize remote cloud management, such as remotely controlling BLE Bluetooth devices, receiving data sent by BLE Bluetooth devices and sending them to the server.
Bluetooth beacon is a small information base station. Beacon technology captures information through Bluetooth intelligent technology and pushes it to mobile devices within communication coverage. Mainly used for indoor navigation, people flow analysis, cargo tracking, etc. For example, push brand promotion information in department stores and the location of catering facilities in time, or push cultural relics information to tourists in museums.
Working principle of Bluetooth gateway
As the Bluetooth gateway is a gateway device integrating Bluetooth and Wi-Fi, that is, the Bluetooth module scans the device and obtains data, and the Wi-Fi module obtains the scanned data and uploads it to the server through the network. Specifically, the Bluetooth module scans its signal coverage. First, when a Bluetooth device enters the range of the Bluetooth gateway, it connects with the Bluetooth part of the Bluetooth gateway and transmits the current data. Then, the Bluetooth part of the Bluetooth gateway receives the data, connects with the WiFi module through the serial port and transmits the data.
Secondly, the WiFi part of the Bluetooth gateway uploads data to the server through the wireless router to control and modify the current situation; Finally, after calculation and analysis, the server displays the positioning information of Bluetooth devices in the front end, and the control instructions can also be transmitted to WiFi of Bluetooth gateway through the server, WiFi to Bluetooth, and Bluetooth to Bluetooth devices to realize control.
