1.1 Little common sense (very important):
TXD: The sender is generally represented as its own sender. Normal communication must be connected to the RXD of another device.
RXD: The receiving end is generally represented as its own receiving end, and normal communication must be connected to the TXD of another device.
In normal communication, the TXD of its own is always connected to the RXD of the device!
Self-receiving: RXD is connected to the TXD of other devices during normal communication. Therefore, if you want to receive the data sent by yourself as the name implies, that is, you receive the data sent by yourself, that is, its own TXD is directly connected to RXD, which is used to test its own transmission and reception. Whether it is normal or not is the fastest and easiest test method. When a problem occurs, the test is first performed to determine whether the product is faulty. Also known as loopback testing.
1.2 Level Logic:
TTL level: Usually the data indicates binary. The specified +5V is equivalent to logic "1". 0V is equivalent to logic "0". It is called TTL signal system and is positive logic.
RS232 level: -12V to -3V, equivalent to logic "0", +3V to +12V logic level, equivalent to logic "1", is negative logic
1.3 Product Features:
1. The core module uses the HC-05 slave module. The lead-out interface includes VCC, GND, TXD, RXD, KEY pin, Bluetooth connection status pin (STATE), unconnected output is low, and the output is high after connection.
2, led indicates the Bluetooth connection status, flashing indicates no Bluetooth connection, slow flashing means entering the AT mode, double flashing indicates that the Bluetooth is connected and the port is opened
3, the bottom plate is set with anti-reverse diode, with 3.3V LDO, the input voltage is 3.6~6V, the current is about 30mA when not paired, about 10mA after pairing, the input voltage is forbidden to exceed 7V!
4, the interface level 3.3V, can be directly connected to a variety of microcontrollers (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly connected, without MAX232 can not go through MAX232!
5, the effective distance of the open space is 10 meters (power level is CLASS 2), more than 10 meters is also possible, but the connection quality of this distance is not guaranteed.
6. After pairing, when using the full-duplex serial port, you do not need to know any Bluetooth protocol, support 8-bit data bit, 1-bit stop bit, and can set the parity communication format. This is also the most common communication format, and does not support other formats.
7, you can enter the AT command mode by pulling the 34 feet to set parameters and query information
8, small size (3.57cm * 1.52cm), factory patch production, to ensure the quality of the patch. And set of transparent heat-shrinkable tube, dustproof and beautiful, and has a certain anti-static ability.
9, can be switched to the host or slave mode through the AT command, can be connected to the specified device through the AT command
10, support the standard baud rate from 4800bps to 1382400bps
1.4 Product use:
After pairing, it only needs to be used as a serial port with a fixed baud rate. Therefore, as long as the serial port device with "fixed baud rate, 8-bit data bit, no parity" communication format can directly replace the original wired serial port. No need to modify the program. Such as data acquisition, smart cars, serial printers, outdoor dot matrix screen control.
Paired with the computer: suitable for communication between the computer and the device through the Bluetooth serial port, the use method is the same as the serial port
Pairing with mobile phone: suitable for communication between mobile phone and device through Bluetooth serial port, using the same method as serial port
Pairing with Bluetooth host: suitable for two devices to communicate directly through the Bluetooth serial port, such as between the MCU and the MCU, between the wired serial port and the MCU, etc.
Flexible use:
The baud rate is changed because the receiving end and the transmitting end can select the respective baud rate, and can be used as a device for baud rate conversion when the amount of data is small.
2.1 How to connect the Bluetooth module to the computer (effective from slave mode)
The following is an example of pairing with a computer with Bluetooth:
First power on the Bluetooth transparent transmission module, at this time led flash, open "my bluetooth position", click "search for devices located within the valid range",
The system will search for the Bluetooth device, the default device name is “linvor” (if the name is modified, it is the modified name, such as “jiayuanelectron”), double click or right click to select “Add Bluetooth Device”.
Enter the pairing password (default is "1234"),
Click “Next”. If the password is correct, the computer and the transparent transmission module will establish a connection. If the Bluetooth serial device has not been installed before, the system will automatically install the driver and generate a virtual serial port.
Click on the configuration and select the appropriate COM port.
I can only choose com5 here, this port is the serial port for computer operation after connection. For example, I am com5 here. When this port is opened, the LED of the Bluetooth module will change from flash to double flash. At this time, only the Bluetooth module is needed. It can be used as a serial port with a fixed baud rate of the computer, except that it is wireless.
TXD: The sender is generally represented as its own sender. Normal communication must be connected to the RXD of another device.
RXD: The receiving end is generally represented as its own receiving end, and normal communication must be connected to the TXD of another device.
