High quality BT5702 UART serial bluetooth module serial Bluetooth adapter Product features and characteristics This product is currently on the market the most simple and easy-to-use a serial Bluetooth adapter can be connected directly responsible for the serial communication microcontroller TX and RX pin, the traditional UART serial communication transformation for wireless serial communication. The goods through the product embedded Bluetooth the SPP protocol stack software, wired serial communication data into virtual Bluetooth serial communication data, and further connected to other devices with Bluetooth communication function via Bluetooth, which replace the traditional serial communication connection within 10 meters wireless serial communication.This product is embedded within the Bluetooth communications protocol software, so there is no need to install additional drivers can be used in a graphical operating system, can also be used in any simple UART serial port device.This product is a TTL level, the need to connect to the pin on the chip can be used, requiring the user to have the expertise of the MCU, non-professionals do not buy this product.The CSR Bluetooth chip supports Bluetooth 2.0 standard. Enhanced BER 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.Users can set by AT command 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.Bluetooth Serial Port Profiles (SPP) with a Bluetooth-enabled laptop, desktop computer equipped with a Bluetooth adapter, Bluetooth cell phone or Bluetooth PDA, Bluetooth GPS Bluetooth serial communication devices support Bluetooth SPP service.Transmit power to comply with the the Bluetooth Class2 standard, built-in technology is mature PCB printed antenna, the stable communication distance of up to 10 meters through walls wireless serial communication. Markets and applications   Use of this product, users do not need to do too many changes to the original wired connectivity solutions quickly wired serial connection to upgrade to the wireless Bluetooth serial connection. 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.Serial communication cable to replace instruments, such as Total Station, mounts, electronic scales, serial printers, etc.For GPS navigation systems, logistics POS data acquisition systems, utility meter reading systems, industrial control and remote telemetryAutomotive ECU wireless detection, intelligent remote control car, wireless LED display, building automation and security monitoring systemMain Specifications Implementation of the standards: Bluetooth SIG v2.0Bluetooth protocol: Bluetooth serial port profile (SPP)Interface: single-wire serial interface (TXD or RXD), two-wire serial interface (TXD and RXD)Communication rate: 1200,2400,4800,9600,19200,38400,57600,115200 bps.Modulation schemes: 2.4G ISM direct sequence frequency hopping (FHSS)Communication distance: 10 meters of open space, Class 2 levelTransmit power: 4 dBmReceive Sensitivity:-79dBmOperating voltage: 4.5V-6V (core module operating voltage of 3.3V)Operating Current: 40mADimensions: 36x32x3 mmInstructions for use  Hardware connectionPress shown the connection method, chip UART serial communication port TXD and RXD pin is connected to the the BT5702 Bluetooth adapter.BT5702 host and slave. The host only be used in conjunction with BT5701 or BT5702 slave can take the initiative to look for from the machine and automatically pair connection. From the use of the machine is more widely, it can be connected with any host supports Bluetooth SPP serial protocol (Series Port Profile), such as a Bluetooth-enabled computer, cell phone, PDA, etc., from machine to wait for Bluetooth Master host to look for and respond to its pairing request. Master and slave default pairing code is "0000". BT5702 interface definitions as shown aboveSupporting lead definition: the red line - power supply (4.5V-6V), the blue line - then MCU TXD, yellow line - then MCU RXD, black line-GND GroundRESET button is used to clear the memory of the host slave address code, the button on the slave invalidAT commands (without the end of the command with a carriage return and line feed)Note 1: You must ensure that the BT5702 baud rate of microcontroller serial port baud rate is always consistent, modified BT5702 baud rate, you must immediately modify microcontroller serial baud rate;Note: You must be the light is flashing non-connection state to send the AT commands. Indicator light is on, the Bluetooth connection is established, the AT command will be sent as a communication content to communication objects.Test commandSend: ATBack: OKModify the Bluetooth serial communication baud rateSending Format: AT + BAUDnReturn information: OK ...Such as sending: AT + BAUD4 and return information: OK9600The communication rate corresponding to the parameter n:n = 1,1200, n = 2,2400, n = 3,4800, n = 4,9600, n = 5,19200, n = 6,38400, n = 7,57600, n = 8,115200 bpsThe Bluetooth serial Parity is setSending Format: AT + PN, no parity, which is the default setting of the adapterSend Format: AT + PO odd paritySend format: AT + PE, even parityModify the Bluetooth nameSending Format: AT + NAMEnameReturn information: OKsetnameSuch as sending: AT + NAMEirxon, returns information: OKsetname Bluetooth name was changed to irxon up. The Bluetooth name should not exceed 20 characters. The host Bluetooth name, please do not try to modify.To modify Bluetooth pairing passwordSending Format: AT + PINxxxxBack: OKsetpinSuch as sending: AT + PIN0000, return information: OKsetpin, Bluetooth pairing password changed to 0000Xxxx is you want to set a new pairing password, 4 figures, this command can be used from the machine or host. Password change could not take effect, need power adapter completely discharge before forgotten the original password.(AT command set various parameters can be powered down to save, modify time, long-term effective) Shipment:1. We will ship the goods within 1-3 work days after payment confirmation.2. We can ship goods via DHL/Fedex/UPS/TNT/EMS.Pls tell us which you prefer. We suggest DHL, because it is cheapest and fast in China.3. We are not responsible for any accidents, delays or other situations related with shipping company. But we will keep focus on the package tracking.4. Any import fees or charges are the buyer's responsibility.Refund & Replacement1. 30-days (After Our Delivery Date) GUARANTEE OF QUALITY. 2. We suggest customers buy new&original goods. We don't sell any New& Bulk parts (Refurbished parts) unless customers accept themselves.3. We 100% make sure the good quality of new&original goods. But we can't 100% control the new&bulk parts.4. The return back delivery cost of new&bulk parts need paid by buyer witout failure reports. The return back delivery cost of new&original goods with failure reports is free for buyer. Company Information and ContactHK shanhai Co., Ltd. is located in the beautiful city of Shenzhen, which is near Hong Kong, with convenient transportation access. We deal with all kinds of electronic components and parts. We perfect ourselves comprehensively and enhance our product quality control and pre-sales and after-sales service by our internal management so that we can satisfy demand from new and old customers better and better.   ...
