In the Internet of Things era,Bluetooth devices have widely penetrated into home,industry,sensing and other scenes,but the limitation of short-distance transmission is still a problem that Bluetooth devices need to overcome.Yingshangwei's Bluetooth Ethernet gateway scheme based on low-power MCU CH9145 is born to solve this problem,which can quickly realize the intercommunication between Bluetooth devices and TCP/IP networks,break the distance limit,and realize remote control and data acquisition.
The low-power MCU CH9145 of
Yingshang Micro-Agent is a highly integrated single-chip solution,with built-in Bluetooth 4.2(BLE)module and 10M Ethernet interface,and a complete TCP/IP protocol stack.The biggest advantage of this scheme is that the data transmission between Bluetooth devices and the Internet can be realized without additional programming,which greatly reduces the development threshold and product time to market.
The highly integrated design of MCU CH9145 makes it possible to realize two-way seamless transmission of Bluetooth data and Ethernet data without additional complicated components.Whether it is a Bluetooth smart home appliance at home or a Bluetooth sensor in an industrial scene,as long as it is connected to the gateway based on the low-power MCU CH9145,it can easily connect to the Internet.Even if it is thousands of miles away,it can control the device and obtain data in real time through a mobile phone,tablet or PC,completely breaking the use boundary of Bluetooth devices.
In addition,the low-power MCU CH9145 also provides multi-channel GPIO interfaces,which can be used to realize remote switch control.Equipped with an ADC acquisition channel to support reading analog data through Bluetooth;At the same time,a UART interface is integrated,and the baud rate can be set flexibly from 300 to 921600bps.Rich interfaces enable various Bluetooth peripherals such as temperature and humidity sensors,intelligent switches and security devices to access the Internet through this gateway.
This Bluetooth Ethernet gateway scheme based on low-power MCU CH9145 is especially suitable for smart home,industrial monitoring,environmental monitoring and other fields.For example,in the smart home scene,users can remotely turn on the air conditioner and lights at home on the way to work;In agricultural monitoring,managers can check the temperature and humidity data in the greenhouse in real time;In the industrial environment,engineers can remotely monitor the running status of equipment and get early warning information in time.It not only solves the networking problem of Bluetooth devices,but also provides a reliable MCU solution for the remote and intelligent upgrade of all kinds of intelligent devices with the characteristics of low power consumption and high adaptability.
