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 wired serial connection into a wireless Bluetooth serial port connection, thereby replacing the traditional serial cable connection, the realization of wireless serial communication. For those who do not wish to have the application field of wired industrial, medical, commercial, surveying and mapping, this product provides a simple and quick wireless serial communication solutions. Widely used in electronic industry express said, scanning gun, serial printer, total station, management type network router and switch, equatorial and so on serial device.
- this product embedded Bluetooth protocol software, so there is no need to install another driver, can be used in the operating system operation interface, also can be used in any operation interface but with RS232 interface device.
- the user need not know the professional knowledge of Bluetooth technology, to 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 a serial port communication code.
- support for Bluetooth Serial Port Profiles (SPP), can be the Bluetooth serial port communication and notebook computer with the Bluetooth function, equipped with USB Bluetooth adapter desktop computer, hand-held Bluetooth PDA, Bluetooth GPS support Bluetooth SPP service equipment.
- built in high-quality 400mA lithium battery, can provide nearly 24 hours of working power to the 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.
- emission power in accordance with the Bluetooth Class2 standard, built-in high sensitivity PCB printed antenna, stable communication distance up to 15 meters, can be wireless serial communication through walls.
Adopt CSR chip Bluetooth support Bluetooth 2 standard rate performance and automatic frequency hopping technology, the enhancement of the error, can ensure the efficient and safe communication, and has stronger anti-interference ability, guarantee the stability and the reliability of communication.
- market and Application
The purpose of using BT5701 is to replace the original serial cable connection, but how to replace, users in the purchase of products before they should have a clear plan. The following is a typical of several BT5701 products use.
Use the connection - from BT5701 and Bluetooth notebook computer, USB Bluetooth adapter, Bluetooth PDA Bluetooth master, this is a way to use the most common BT5701. The machine is installed in the serial port equipment, wait for the Bluetooth master to find, when the main equipment BT5701 find from the machine, send pairing request from the master device, and in the main equipment to enter the correct password to verify from the machine pairing (BT5701 default pairing password is 0000), paired connection is completed, the system host the equipment will be assigned a Bluetooth virtual serial port number for this Bluetooth connectivity, application program running on a host device only needs to be set up to use the serial number, then with the BT5701 serial communication, serial port connected with the Bluetooth adapter and the serial communication serial port equipment.
- BT5701 from the machine and the BT5701 host used in pairs. The host and connected with two serial connected in the original serial cable from the host machine respectively, after power on automatically search from the machine and complete from the machine matched connection. After a successful connection, the master and the slave Bluetooth status indicator light is no longer flashing, into a long bright state. The master and slave are connected, even if the two different baud rate, can also be mutual transmission of data. Using master-slave pairs without setting, two modules are after power can carry out serial communication. If the host and the distance is too far from the machine is interrupted, the master and the slave Bluetooth status indication exhibit of lanterns recover to the connection before flashing status, when they again approached, will automatically revert to the state of the connection.
BT5701 host is connected with the Bluetooth from equipment used: currently on the market common Bluetooth GPS and Bluetooth printer, internal general use Bluetooth from the machine, use the AT command to set to and from the host machine same passkey, close together can be connected.
Express industry, the user can adapt with the Shanghai Yaohua XK-3190-A1, XK-3190-A7, XK-3190-A27, XK-3190-A15E and so on electronic, but some electronic weigh baud rate is 9600, some are 1200 so express industry users please message note baud rate and other parameters at the time of purchase. We can give for modification.
