Product selling point:
1. RS-232 interface Bluetooth adapter with embedded Bluetooth protocol stack. The main function of the product is to replace the traditional serial cable connection. Users can quickly upgrade the original serial cable connection to a wireless serial Bluetooth connection without making too many changes to the original cable connection scheme. For industrial and commercial applications that do not wish to have too many connections, this product provides a simple, fast, safe and reliable wireless solution.
2. This product is embedded with the Bluetooth communication protocol, so there is no need to install additional drivers, it can be used in Windows system,
It can also be used in non-graphical operating systems such as DOS and Linux.
3. Users do not need to understand the professional knowledge of Bluetooth communication technology. For users, it is still ordinary serial communication, which is different from traditional serial communication.
There is no difference in cable connection, communication program developers only need to write serial communication code.
4. Adopt CSR Bluetooth chip that supports Bluetooth 2.1 standard. Enhanced BER error rate performance and automatic frequency hopping technology to ensure efficient safety
Complete communication, and has stronger anti-interference ability to ensure the stability and reliability of communication.
5. Users can set a total of twelve different baud rates from 1200bps to 1382400bps through AT commands (the default value is 9600,n,8,1), and can also set a more personalized Bluetooth name for the device.
6. Support Bluetooth Serial Port Profiles (SPP), can connect and communicate with Bluetooth-enabled notebook computers, desktop computers equipped with Bluetooth adapters, handheld Bluetooth PDAs, Bluetooth GPS and other devices that support Bluetooth SPP services.
7. The transmission power conforms to the Bluetooth Class2 standard, with a built-in high-sensitivity PCB printed antenna, the stable communication distance can reach 15 meters, and wireless data transmission can be carried out through the wall.
8. The RS232 serial port Bluetooth adapter needs to supply power to the adapter through the MiniUSB interface on the adapter.
9. Equipped with a RESET reset button, which can delete the paired device information saved in the adapter and re-pair with a new Bluetooth device.
