Solution of high integration BLE Bluetooth module based on virtual serial port

　　In the Internet of Things terminal and industrial control equipment,Bluetooth module undertakes the function of short-distance wireless data exchange.RAMSUN provides a set of progressive hardware solutions covering single channel,dual channel and triple channel communication for typical scenarios such as wireless serial port devices,USB interface bridging and multi-channel concurrent communication.The Bluetooth module is designed based on BLE virtual serial port technology,which is fully compatible with mainstream conventional serial port applications,and can quickly realize wireless data interoperability of devices without complicated secondary development,and is widely suitable for industrial control and intelligence.

 

　　CH9140 Bluetooth-to-serial chip is a basic high-performance Bluetooth module,which focuses on the bidirectional data transmission between BLE Bluetooth and single serial port,perfectly adapts to the wireless transformation of conventional serial port equipment,that is,it can be used immediately,greatly shortening the equipment development cycle.CH9141 Bluetooth serial port transparent transmission chip has been upgraded on the basis of basic transparent transmission function,supporting dual-mode configuration of serial port AT command and Bluetooth transmission,equipped with MODEM contact signal,and expanding practical functions such as GPIO,synchronous GPIO and ADC data acquisition to adapt to intelligent devices with diversified functions.

 

　　According to the application scenario of multi-serial port equipment,CH9142 Bluetooth-to-dual serial port module is optimized,which can realize stable data transmission between Bluetooth and two serial ports at the same time,is compatible with traditional serial port programs,and can complete wireless adaptation without changing the original equipment programs.As a three-way composite Bluetooth module,CH9143 integrates the triple transmission channels of BLE,UART and USB to realize the free switching and mutual transmission of three types of interface data,and has a wider functional coverage,which can meet the multi-interface communication requirements of complex devices and is an efficient and low-cost wireless communication solution.

 

　　The virtual serial port design of BLE Bluetooth module shields the bottom details of Bluetooth protocol stack,so that the traditional serial port device can be upgraded to a wireless node only by changing the physical connection mode,which greatly shortens the product development cycle.For applications that need multi-slave management,USB online debugging or dual serial port aggregation,the above chipset provides a clear gradient and ready-to-use Bluetooth module selection path,taking into account the balance between performance,cost and development efficiency.If you need BLE Bluetooth module,please feel free to call.
