BLE-TPT Bluetooth serial port transparent transmission module is designed based on high-performance CH9141 chip,which is a ready-to-use module and can be seamlessly integrated into various products.Its design concept focuses on simplifying the development process,while providing rich hardware interfaces and flexible configuration methods.The module not only provides a standard serial communication interface,but also is equipped with GPIO(General Input and Output)and ADC(Analog-to-Digital Converter)pins,which is convenient for users to connect sensors or actuators and realize more complex logic control.
 

Bluetooth serial port transparent transmission module supports BLE 4.2 protocol and can run in broadcast mode,master mode and slave mode.Its stable RF performance ensures that the Bluetooth transmission distance can reach 100 meters in an open environment,which is enough to cope with most indoor and outdoor application scenarios.
 

The core function of BLE-TPT Bluetooth serial port transparent transmission module is to realize transparent transmission between Bluetooth interface data and serial port(UART)data.This means that for the devices connected to the serial port of the module,the data sending and receiving process is no different from using traditional cables.Bluetooth serial port transparent transmission module adopts Bluetooth virtual serial port technology.On the computer side,just install the corresponding virtual serial driver,and the system will automatically generate a virtual COM port.This design shields the complicated communication protocol at the bottom of Bluetooth,and enables users'existing applications developed based on conventional serial ports to communicate with remote devices with zero modification.
 

According to different application scenarios,the Bluetooth serial port transparent transmission module supports multiple Bluetooth working modes:

①Slave mode:This is the most commonly used mode.As a Bluetooth peripheral,the module waits for the connection of mobile phone,computer or other master devices.In this mode,users can customize parameters such as Bluetooth name and manufacturer information to create a unique device logo.

②Host mode:Bluetooth serial port transparent transmission module can actively scan and connect other slave devices,which is suitable for constructing point-to-point or star-shaped networks.

③Broadcast mode:The module continuously sends out data packets,which is suitable for scenes requiring one-way data distribution or beacon application.
 

No matter what mode you are in,once the Bluetooth connection is successful,the Bluetooth serial port transparent transmission module will be recognized as an available virtual serial port device,whether on the PC side or the mobile device side,which is very intuitive to use.BLE-TPT Bluetooth serial port transparent transmission module provides an efficient and reliable wireless transformation scheme for all kinds of serial port equipment with its comprehensive functions,strong compatibility and friendly secondary development environment.
