Using CC2540 Bluetooth 4.0 solution,Adopt CC2540 Bluetooth 4.0 solution  

4.0 Bluetooth features:This paragraph4.0 Bluetooth 232, 485, 422 slave devices support all Bluetooth 4.0 version APP software, but when 2 Bluetooth 4.0 modules are required as a master-slave pair connection, they can only be connected with the same model of the store''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s Bluetooth 4.0 module host and cannot be compatible with 2.0 Bluetooth.BLE serial port rate is low but can support Apple IOS system,Serial port transmission rate 4.0 is 3 times slower than 2.0（The upper limit of 4.0 rate is 2.5K/sec. 2.0 is 10K/sec as the normal rate. There may be a delay when using 4.0 Bluetooth in real-time monitoring.）.

To use this USB serial port 4.0 Bluetooth, it must be used in conjunction with our 4.0 slave machine（4.0 Bluetooth 232 or 485）, 2 master/slave sets are automatically connected when powered on.

Product introduction: compact size “length 52X width 32X height 16mm”, complete functions, abundant accessories, industrial-grade interface, super cost-effective, built-in antenna and external antenna for dual purposes, increase the signal to ensure that the signal is more than 10 meters effective = Super anti-interference. The product can convert the wired serial port into a wireless Bluetooth mode, replacing your original USB-to-serial data cable, and realize the wireless connection from the computer to the device serial port, and from the tablet or mobile phone to the device serial port. The default parameter baud rate is 9600 n 8 1  password 8888, built-in lithium battery can work independently for 6-8 hours, with USB+5V mobile phone charger, 232 with male and female conversion head, 422,485 with large screw terminal. The host with the reset button can restart the search pairing function.

PLC models that have successfully tested the Bluetooth connection: Mainstream  Delta/XinjeSeries, Mitsubishi/FATEK, South Korea LG-K series, as long as they are compatible!   For more PLC and MCU Bluetooth connection operation essentials, please consult me ??and provide remote operation services!

Product instructions: First connect the product to your device serial port and turn on the power switch at the rear of the product, wait a few seconds to see the green light flashing as the slave waiting for working status.  

 Note: When the rear switch of the product is in the “on” position, the internal lithium battery is turned on. At this time, the external USB power supply can be used to charge the battery. When the switch is in the “off” position, the external USB power supply can only supply power to the module, and cannot charge the battery.

“ Provide 7-24V external power supply mode customization, the shell remains unchanged, and the voltage conversion module is external."  The modification fee is 10 yuan  changes to 100 yuan / only free shipping.

”Provide a battery-free version of customization and free modification, and also reduce the material cost of 10 yuan, and change it to 80 yuan per package.

1: The product is used as a slave module to be connected by other master modules. After setting the same password, turn it on and wait for it to be connected. Start the search by computer bluetooth adaptation or built-in bluetooth or mobile bluetooth to find my module, start pairing input 8888 after pairing is successful, start the software to call the correct bluetooth virtual serial port number（Computer equipment management-search in the port COM item）To connect to your device, the Bluetooth wireless serial port data transmission and reception is realized. The operation is the same as your original wired connection, but the calling com is different.

2: Use the serial port assistant to send the command “AT+ROLE=M ” is to set the module as the host. After power on, it will automatically search for peripheral modules and pair and connect. The hole on the back of the product is the clear record button. Search for new modules again.

 4.0 Bluetooth features: this model4.0 Bluetooth USB devices can only be connected with the 4.0 Bluetooth slaves of our store, and are not compatible with 2.0.Serial port transmission rate 4.0 is 4-5 times slower than 2.0（The upper limit of the rate of 4.0 is 2.5K/sec. 2.0 is the normal rate of 10K/sec.There may be a delay when using 4.0 Bluetooth in real-time monitoring.）.

To use this USB serial port 4.0 Bluetooth, it must be used in conjunction with our 4.0 slave machine（4.0 Bluetooth 232 or 485）, 2 master/slave sets are automatically connected when powered on.

3: The computer USB driver is installed normally, and the device management sees "Prolific USB-to-Serial com port(com4)"

 This product uses the serial port assistant to send AT commands to set parameters

1: The command “AT+ROLE=M ” is to set the module as the host, which is also the default mode. After power on, it will automatically search for peripheral modules and pair and connect.  

Product default: host, password 000000,  baud rate 9600,  data bit 8, stop 1, no parity, no flow control

2: Default name: DXT2C,  can be changed arbitrarily, send command AT+NAMEXXXX

4: Command “AT+ROLE=S ” is to set the module as a slave

5:AT+BAUD=X modify baud rate（For example: AT+BAUD=9600   is set to 9600

X is: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600, 1382400.
