Product Description
The function and characteristics of the product
The main function of BT5701 serial Bluetooth adapter is to replace the traditional RS232 serial communication cable. BT5701 has built-in Bluetooth SPP protocol software, can be connected to the serial port cable into a wireless Bluetooth serial port connection, to replace the traditional serial cable connection, serial communication and wireless. For those who do not wish to have the application field of industrial, medical, business line, surveying and mapping, this product provides a quick and easy solution to the wireless serial communication.
- this product embedded Bluetooth protocol software, so do not need to install the driver, can be used in the operating system interface, and also can be used in any operation interface with RS232 serial port device.
- the user does not need to know the professional knowledge of Bluetooth technology, for the user, or the common serial communication, serial cable is connected with the traditional and there is no difference, application developers only need to write the serial communication code.
- support Bluetooth Serial Port Profiles (SPP), can be Bluetooth serial communication with notebook computer with Bluetooth function, equipped with a USB Bluetooth adapter, desktop computer, handheld Bluetooth PDA, Bluetooth GPS, Bluetooth SPP service equipment.
The built-in high quality 400mA lithium battery, can provide nearly 24 hours of work to the power adapter. The user can through the MiniUSB interface adapter to adapter power supply and internal rechargeable lithium batteries.
The user can through the AT command set from 1200BPS to 115200bps a total of eight different baud rate (the default value is 9600, N, 8,1), you can also set a more personalized Bluetooth name for the device, or modify the Bluetooth pairing password.
The transmit power with Bluetooth Class2 standard, built-in high sensitivity PCB printed antenna, stable communication distance up to 15 meters, can be wireless serial communication through the walls.
Adopt the CSR Bluetooth support Bluetooth 2 standard, automatic frequency hopping rate performance and the enhancement of the error, can ensure the safety and the efficiency of communication, and has stronger anti-interference ability, guarantee the stability and reliability of communication.
In the market and its application
The purpose of using BT5701 is to replace the original serial cable connection, but how to replace the user before buying the product should have a clear plan. The following is a typical use of BT5701 products.
The use of BT5701 and Bluetooth connection - from laptops, USB Bluetooth adapter, Bluetooth PDA Bluetooth master, this is a way of using the most common BT5701. The machine is installed in the serial port on the device, wait for the Bluetooth master to find, when the main equipment to find BT5701 from the machine after a request from the master device, matching, and the main equipment to enter the correct password verification from pairing (BT5701 factory default pairing password is 0000), paired bluetooth connected after the completion of the main system the equipment will be assigned a Bluetooth virtual serial port number for the Bluetooth connection, the application will run on a host device only needs to be set up to use the serial number, you can with the BT5701 serial communication, serial port and Bluetooth adapter connected with the serial port equipment serial communication.
The BT5701 from the machine and the BT5701 host used in pairs. The host and the two serial connected in serial cable from the machine, the host power will automatically search from the machine and machine to complete the connection from the pairing. After a successful connection, the master and slave Bluetooth status indicator light is no longer flashing, into a long bright state. And from the host machine is connected, even if the two different baud rate, but also can transfer data. Master used in pairs without setting, two modules are power can be performed after the serial communication. If the distance is too far from the host machine and interrupted, the master and slave Bluetooth status indicator exhibit of lanterns restored before the connection is flashing, when they again approached, will automatically return to the state of the connection.
The BT5701 host to connect Bluetooth devices use: currently on the market common Bluetooth GPS and Bluetooth printer, the general use of Bluetooth from inside the machine, use the AT command to the host and from the machine set the same passkey, close together can be connected.
