In 2016, Dingxintu launched a new classic Bluetooth serial port multi-function product
MultifunctionWireless Bluetooth 4.0BLE serial port adaptation 158 yuan/only Super high cost performance!
At the same time, it supports Bluetooth 232, 485, TTL, three serial signals.
Using CC2540 Bluetooth 4.0 solution,Adopt CC2540 Bluetooth 4.0 solution
4.0 Bluetooth features: this model4.0 Bluetooth 232, 485, 422 slave devices can only be connected with our 4.0 Bluetooth USB host, not compatible with 2.0.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.).
The module is a pure slave and does not support being connected by the HC06 host. If BLE wants to connect the module to the module, you must use our USB4.0 adapter-supporting use, that is, 2 master/slave sets are automatically connected after power on.
The original price is 158 yuan, a full set: you can choose and match according to your needs

It can convert the wired serial signal into wireless Bluetooth TTL / 232/485 three kinds of serial signals, connect with the wireless serial port of mobile phones and computers, instead of the wired serial port, the effective distance is 10-20 meters, built-in 900MAh lithium battery-work for 30 hours. “ Provide custom built-in 9-24V power supply mode, the shell remains unchanged"
The product only converts the serial port signal received by Bluetooth, and does not support wired conversion such as wired 232 to 485. The big black switch on the right side of the product is the 232/485, TTL signal selection switch. The small black switch on the left is the power switch-that is, switch the machine.
The USB on the side of the product means that the charging port is fully charged. The red LED light is off, and the green LED on the panel is always on.
The product Bluetooth supports master-slave integration, and AT is valid when not connected(Similar to HC06 mode).
The 232/485 and TTL three serial modes of the product cannot be output at the same time, only one of the three can be selected.
Reminder: When the large switch on the right is in the 232 range, the TTL signal of the small 5-pin TTL interface on the left is valid.
Pin 1 and Pin 6 of DB9 are the A and B terminals of product 485 with 3.3V output, so you don’t have to worry about the passive 485 of your device. But pins 1-6 are shared with 232(When using the DB9-485 terminal, it defaults to pin 1 and pin 2 to be effective. At this time, you need to short-circuit the terminals 2, 6, that is, connect my 6 pin B to pin 2 B.), When used as 232, pins 1, 6 will be electrified. If it affects the communication of 232 serial port, please connect only to pin 2.3.5 of the serial port!
Note: Sending AT is valid without connection-easy to use and different from PIO pull-up mode,Single chip microcomputerSend AT commandintervalwithWaiting for replyIt takes longer because the module has to analyze whether the serial port is coming from data or instructions. It is recommendedInterval and waitOK replytimeIt is: 500-900ms can not be lengthened.
The product module is the slave by default, the password is 8888, the baud rate is 9600, and the name is dxt2C, which can be changed to the master.
Product connection distance description: The use distance in the Bluetooth connection is 40% farther than the start connection, that is, the transmission can be 20 meters on the connection. If you want to restore the connection, you must be close to 12 meters. Attenuation, the attenuation is most obvious when the partition wall turns again. If you want to use it at a distance of more than 20 meters, please choose similar products of our store''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s 100-meter Bluetooth.http://item.taobao.com/item.htm?spm=686.1000925.0.0.ttFQ5Z&id=41221869153
Product instructions: first connect the product to your device serial port and turn on the power switch of the product, wait a few seconds to see the green light flashing as the slave waiting for working status. “ Provide custom built-in 9-24V power supply mode, the shell remains unchanged"
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 paired connections. The hole on the back of the product is the clear record button. Press it to search again. New module.
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.
Bluetooth connection conditions:
1: The adapter''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s Bluetooth password should be consistent with “PLC 232 Bluetooth” the default password is “000000 baud rate 9600
2: Within a reasonable range of 8-15 meters
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
