In 2015, Dingxintu launched a new classic Bluetooth serial port multi-function product
The original price of this link is 159 yuan
106 yuan is With the simplest configuration“Pure 232”The product calculation is as follows:
Original price 159 yuan Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t 2（7 yuan）, 3（20 yuan）, 5（4 yuan）,7B（15 yuan）,8 （7 yuan）
Calculate 159 minus（7+20+4+15+7=53）=106
Ie: don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t
2: USB cable + small USB charger Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t take 7 yuan off
3: Built-in 900MAh lithium battery, 2 hours full charge can work for more than 30 hours Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t take 20 yuan off , Note: The battery logistics can only be transported by land but not by air
5: One USB to TTL module Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t lose 4 yuan
7: The product is composed of three parts: Bluetooth module + 232 conversion + 485 conversion,
A: Only use pure 485 Bluetooth, remove the 232 part Can be reduced by 10 yuan
B: Only use pure 232 Bluetooth, remove the 485 part Can be reduced by 15 yuan It can also be changed to have its own male-to-female conversion function-standard female head + adapter
8: Do not outside the box Minus 7 yuan
9: No product shell Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t lose 5 yuan
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!
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.
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, which flashes when the connection is successful and not connected.
Product Bluetooth supports master-slave integration, sending 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.
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. However, pins 1-6 are shared with 232. When used as 232, pins 1, 6 will be charged. If it affects 232 serial communication, please connect only to 2.3.5 pins!
Note: Sending AT is effective if it is not connected-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 disconnect to restore the connection, you must be close to 12 meters. The distance between obstacles will be attenuated. The attenuation is the 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.
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 your device, you realize the Bluetooth wireless serial port data transmission and reception. The operation is the same as your original wired connection, but the com is different.
Tip: There is a situation that will cause the connection to fail, that is, your software does not support Bluetooth virtual serial port connection. At this time, you must use my dedicated USB Bluetooth serial adapter to connect.https://item.taobao.com/item.htm?spm=a1z10.3-c.w1017-1998020059.12.3ctDvK&id=521362150564&
2: Use the serial port assistant to send instructions“AT+ROLE=M” is to set the module as the host, after power on, it will automatically search for peripheral modules and paired connections, and short-circuit the product“The TTL signal port is by the antenna end-the second and third pins from the left”（Small white 5-pin connector on the side of the product）It is to clear the record and search for the new module again. The product uses a TTL port to connect to a computer U port via a USB to TTL module, which can be used for parameter setting or Bluetooth serial connection.
Product default: slave, password 8888, Baud rate 9600, Data bit 8, stop 1, no parity, no flow control
Default DXT2C, Can be changed arbitrarily, send command AT+NAMEXXXX
AT+PINXXXX modify password
AT+BAUDX modify baud rate（For example: AT+BAUD4 is set to 9600
X is: 1=1200, 2=2400, 3=4800, 4=9600, 5=19200, 6=38400, 7=57600, 8=115200, 230400, 460800, 921600, 1382400.
AT+ROLE=S is set as slave
