BT5701 Serial Bluetooth Adapter
13510272068
Product model: BT5701
Product name: RS232 wireless serial port communication Bluetooth adapter
Manufacturer: Beijing Shuimuhang Electronic Equipment Co., Ltd.
■Product functions and features
The main function of the BT5701 serial Bluetooth adapter is to replace the traditional RS232 serial communication cable. BT5701 has built-in Bluetooth SPP protocol software, which can transform the wired serial connection into a wireless Bluetooth serial connection, thereby replacing the traditional serial cable connection and realizing wireless serial communication. For those applications in the fields of industry, medical treatment, commerce, surveying and mapping that do not want to have too many connections, this product provides a simple and fast wireless serial communication solution.
●This product is embedded with Bluetooth protocol software, so there is no need to install additional drivers. It can be used in an operating system with an operating interface, and it can also be used on any device without an operating interface but with an RS232 serial port.
●Users do not need to know the professional knowledge of Bluetooth technology. For users, it is still ordinary serial communication, which is no different from traditional serial cable connection. Application developers only need to write serial communication code.
●Support Bluetooth Serial Port Profiles(SPP), Bluetooth serial communication can be carried out with Bluetooth-enabled notebook computers, desktop computers equipped with USB Bluetooth adapters, handheld Bluetooth PDAs, Bluetooth GPS and other devices that support Bluetooth SPP services.
●Built-in high-quality 400mA lithium battery, which can provide nearly 24 hours of working power to the adapter. The user can supply power to the adapter and charge the internal lithium battery through the MiniUSB interface on the adapter.
●Users can set eight different baud rates from 1200bps to 115200bps through AT commands(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.
●Transmitting power conforms to Bluetooth Class2 standard, built-in high-sensitivity PCB printed antenna, stable communication distance of up to 15 meters, and wireless serial communication through walls.
●Using CSR Bluetooth chip that supports Bluetooth 2.0 standard, its enhanced error rate performance and automatic frequency hopping technology can ensure efficient and safe communication, and have stronger anti-interference ability to ensure the stability and reliability of communication.
■Markets and Applications
The purpose of using BT5701 is to replace the original serial cable connection, but how to replace it, the user should have a clear plan before purchasing the product. The following are several typical usage methods of BT5701 products.
●BT5701 slave is connected to Bluetooth master devices such as Bluetooth notebook computers, USB Bluetooth adapters, Bluetooth PDAs, etc. This is the most common way to use BT5701. The slave is installed on the serial device and waits for the Bluetooth master to find it. When the master finds the BT5701 slave, it sends a pairing request from the master and enters the correct slave pairing password on the master for verification.(BT5701 factory default pairing password is 0000), After the pairing connection is completed, the system of the Bluetooth master device will assign a Bluetooth virtual serial port number for the Bluetooth connection. In the future, applications running on the master device only need to set the serial port number to communicate with the BT5701. Perform serial communication with the serial device connected to the serial Bluetooth adapter.
●BT5701 slave and BT5701 master are used in pairs. The host and slave are respectively connected to the two serial ports connected by the original serial cable. After the host is powered on, it will automatically search for the slave and complete the pairing connection with the slave. After the connection is successful, the Bluetooth status indicators of the master and slave will no longer flash, and become a steady state. The host and the slave are connected, even if the baud rates of the two are different, they can transmit data to each other. The master-slave pair use does not need to be set up, and serial communication can be carried out after both modules are powered on. If the distance between the master and slave is too far and the connection is interrupted, the Bluetooth status indicators of the master and slave will return to the blinking state before they were not connected, and when they are close again, they will automatically return to the connected state.
● BT5701 host connects to Bluetooth slave devices: the common Bluetooth GPS and Bluetooth printers on the market currently use Bluetooth slaves internally. Use AT commands to set the master to the same pairing code as the slave, and connect them close together.

■Purchase instructions
BT5701 serial port Bluetooth adapter has male and female heads, as well as master and slave. When customers purchase the BT5701 serial Bluetooth adapter, they should specify male or female, master or slave according to their actual use. The following is a description of the selection of male and female master slaves. Please read carefully before purchasing.
●BT5701 master can only communicate with BT5701 slaves. It can automatically search for slaves and complete the pairing connection with slaves with the same pairing password, and remember the address and password of the last paired slave, and it will only find what it remembers after powering on The master will give up the memory and search for a new slave until the pairing clear button is pressed.
●The use of BT5701 slave is much more extensive! The slave can only wait for the Bluetooth master device to search, and can pair and connect with Bluetooth notebook computers, computer Bluetooth adapters, Bluetooth PDAs and other Bluetooth master devices. The slave cannot remember the address of the master, so it is meaningless to press the pairing clear button of the slave.
●BT5701 is also divided into male and female, which depends on the serial port on the device to be connected to BT5701. If the serial port on the device is DB9-F female, you should choose the male BT5701; if the serial port on the device is DB9-M male, you should choose the female BT5701.
Therefore, the BT5701 serial Bluetooth adapter can be further subdivided into the following four types:
1. Male slave, 2. Female slave, 3. Male master, 4. Female master.
In practical applications, the male slave is the most widely used type, and its sales account for more than 80% of the sum of the above four types.(The default shipment is male slave)
