Product functions and features

This product is an embedded Bluetooth protocol stack RS-232 interface bluetooth adapter. The main function of the product is to replace the traditional serial cable connection, users do not need to do too many changes to the original wired connection scheme, you can quickly upgrade the original serial cable to connect to the wireless serial port Bluetooth connection. This product provides a simple, fast, secure and reliable wireless solution for industrial, medical, commercial and other applications that do not want to have too many connections.
] this product into the interior of the Bluetooth communication protocol, so there is no need to also install the driver, can be used in Windows system, can also in DOS, Linu and other non graphic of the operating system in use.
] users do not need to understand Bluetooth communication technology professional knowledge, for the user, or the common serial communication, with the traditional serial cable connection and there is no difference, communication program development staff just write the serial communication code can be.
Adopt CSR chip Bluetooth Bluetooth 2.1 standard. Enhanced BER error rate performance and automatic frequency hopping technology, which can ensure high efficient and secure communication, and has a stronger anti-interference ability, to ensure the stability and reliability of the communication.
] users can through the at commands to set from 1200 to 1382400bps twelve different baud rate (the default value is 9600, N, 8,1), you can also set a more personalized Bluetooth name for the equipment.
] support Bluetooth serial port profile (SPP), and notebook computer with the Bluetooth function, equipped with Bluetooth adapter of desktop computers, handheld PDA Bluetooth, Bluetooth GPS Bluetooth spp service equipment connection and communication.
] emission power conforms to the Bluetooth class2 standard, built-in high sense of degree PCB printed antenna, stable communication distance can be up to 15 meters, pass through the wall for wireless data transmission.
- RS232 serial Bluetooth adapter through the MiniUSB interface adapter for power adapter.
