Realize the communication between BLE Bluetooth and Wifi through serial port. Bluetooth beacon is a broadcast protocol based on low-power Bluetooth protocol, and it is also a low-power Bluetooth device using this protocol. But it can't be connected to any low-power Bluetooth host, and it is usually placed in a fixed location indoors and broadcast continuously to the surrounding area.
The structure of Bluetooth gateway determines that it can be flexibly applied to various Bluetooth +Wi-Fi application scenarios. For example, by adding colored lights to the intelligent Bluetooth gateway, the mobile phone can remotely control indoor lighting, sockets, switches, remote controllers, door locks, curtains, water meters, electricity meters and so on.
Bluetooth gateway mainly has scanning function, connection function, data transmission function and indoor positioning function. It can be flexibly applied to schools, shopping malls, factories, nursing homes, exhibition halls, tourist attractions, airports and other places to realize application scenarios such as personnel or asset positioning and sensor data collection.
Bluetooth gateway function
Bluetooth gateway can store and forward data transmitted by Bluetooth devices, thus realizing long-term storage and transmission of data. This is very useful for smart homes, smart factories and other scenes that need remote monitoring equipment.
Bluetooth gateway can analyze and process the data transmitted to the Internet, so as to draw useful information and conclusions. This is very useful for some scenarios that need data analysis, such as intelligent health monitoring and intelligent transportation.
Bluetooth gateway can encrypt and authenticate the transmitted data, thus ensuring the security of the data. This is very important for some scenarios that need to protect data security, such as finance and medical care.
