Place of Origin: Guangdong China (Mainland) Brand Name: hkshanhai Model Number: BT5701 Serial port communication bluetooth: BT5701 Bluetooth master device BT5701 Bluetooth master device: the BT5701 host connected Bluetooth from the device Implementation of the standards: serial port profile (SPP) Packaging & Delivery Packaging Detail: box Delivery Detail: 2days Specifications High Quality Bluetooth adaptor 1: Bluetooth protocol: Bluetooth serial port profile (SPP) 2: Modulation: 2.4G Direct Sequence. High Quality Serial port communication bluetooth adapter BT5701 malBT5701 three dimensional diagrame and female first two the, BT5701M male adapter the, BT5701F female adapter purchase required. Note: The host can only be connected to the slave, if you buy a host is necessary buyer slave. Slave can connect with any Bluetooth adapter. product features and featuresThe main function of the the BT5701 serial Bluetooth adapter is an alternative to traditional RS232 serial communication cable. BT5701 has an embedded Bluetooth SPP protocol software, and can be wired serial connection into a wireless Bluetooth serial port connection, thereby replacing the traditional serial cable connection, wireless serial communication. For those who do not want to have too many connections the field of industrial, medical, commercial, mapping applications, the product provides a simple and fast wireless serial communication solutions.This product is embedded within the Bluetooth protocol software, so there is no need to install the driver, you can use operator interface of the operating system, but any operator interface with RS232 serial devices.The user does not need to understand the Bluetooth technology expertise, for the user, or an ordinary serial communication, and there is no difference between the traditional serial cable connection, application developers only need to write the serial communication code can be.Bluetooth Serial Port Profiles (SPP), can be equipped with a Bluetooth-enabled laptop to USB Bluetooth adapter desktop computers, handheld Bluetooth PDA, Bluetooth GPS, Bluetooth serial communication devices support Bluetooth SPP service.Built-in quality 400mA lithium battery, power adapter provides nearly 24 hours of work. MiniUSB interface adapter adapter power supply and charge the internal lithium battery.Users can set via AT commands from 1200bps to 115200bps a total of eight different baud rate (the default value is 9600, n, 8,1), also the name of the Bluetooth device settings more personalized, or modify the Bluetooth pairing password. transmit power in line with the Bluetooth Class2 standard, built-in high-sensitivity PCB printed antenna, stable communication distance up to 15 meters through walls for wireless serial communication. CSR Bluetooth chip supports Bluetooth 2.0 standard, its enhanced error-rate performance and automatic frequency hopping technology to ensure the efficient and secure communication, and has stronger anti-interference ability to protect the stability and reliability of the communication.The BT5701's purpose is to replace the original serial cable connection, but how alternative, users should have a clear plan before purchase. The following is the BT5701 several typical useBT5701 Bluetooth master device connected to the machine with a Bluetooth laptop, USB Bluetooth adapter, Bluetooth PDA use, the BT5701 is the most common kind of use. Slave installed serial devices, waiting for Bluetooth master device to find, when the master device to find BT5701 from the machine, from the master device issued pairing request on the master device input the correct slave pairing password for authentication (BT5701 factory default pairing password 0000), upon completion of the mating connector, Bluetooth master system for the Bluetooth connection assigned a Bluetooth virtual serial number, after the applications running on the master device is only set to use the serial number, can be carried out with the BT5701 serial communication, thus serial communication serial Bluetooth adapter to connect serial devices. BT5701 and BT5701 host slave pairs. Master and slave, respectively, then the original serial cable to connect the two serial port, the host power will automatically search from the machine and complete the pairing connection with slave. After a successful connection, the master and slave Bluetooth status indicator is no longer flashing state becomes long bright. Master and slave connection, even if the baud rate of the two, also can transfer data. Without setting master and slave are used in pairs, two modules on power after the serial communication. If the master and slave is too far away to cause the connection is broken, the master and slave Bluetooth status indicator will be restored to the state not connected before flashing will automatically revert to when they are again close to the connection status.the BT5701 host connected Bluetooth from the device: the common Bluetooth GPS and Bluetooth printer currently on the market, the internal general use of Bluetooth slave, with the AT command set host slave pairing code, close together can be connected.Main SpecificationsImplementation of the standards: Bluetooth SIG v2.0Bluetooth protocol: Bluetooth serial port profile (SPP)ommunication rate: 1200,2400,4800,9600,19200,38400,57600,115200 bps Modulation: 2.4G Direct Sequence Frequency Hopping (FHSS) communication distance: 15 meters of open spacetransmit power: 3 dBm, Class2 Receiver Sensitivity:-80dBm....
