Product Description

Master-slave Wireless Serial Port Transmission Bluetooth Module HC-05 with Baseplate

HC-05 compatible 3

1.1 Common sense (very important):
TXD: sending end, generally expressed as its own sending end. Normal communication must be connected to RXD of another device.
RXD: receiving terminal, generally expressed as its own receiving terminal. Normal communication must be connected to TXD of another device.
In normal communication, TXD is always connected to RXD of the device!
Spontaneous self receiving: RXD is connected to TXD of other devices during normal communication, so if you want to receive the data sent by yourself as the name implies, that is, you want to receive the data sent by yourself, that is, your TXD is directly connected to RXD, which is used to test whether your sending and receiving are normal. It is the fastest and simplest test method. When there is a problem, you should first do this test to determine whether the product is faulty. Also called loop back test.

1.2 Level logic:
TTL level: generally, binary is used for data representation. It is specified that + 5V is equivalent to logic "1" and 0V is equivalent to logic "0". It is called TTL signal system, which is positive logic
RS232 level: adopt - 12V to - 3V, equivalent to logic "0", + 3V to + 12V, equivalent to logic "1", negative logic

1.3 Product characteristics:
1. The core module uses hc-05 from the module, and the outgoing interface includes VCC, GND, TXD, RXD, key pin, Bluetooth connection status outgoing pin (state). The unconnected output is low, and the connected output is high
2. LED indicates Bluetooth connection status, flash indicates no Bluetooth connection, slow flash indicates entering at mode, double flash indicates Bluetooth is connected and the port is opened
3. Anti reverse diode with 3.3V LDO, input voltage of 3.6-6v, current of about 30mA when not paired, about 10mA after pairing, input voltage shall not exceed 7V!
4. The interface level is 3.3V, which can be directly connected to various single-chip computers (51, AVR, PIC, arm, MSP430, etc.), 5V single-chip computers can also be directly connected without MAX232 or MAX232!
5. The effective distance of open space is 10m (Class 2), and it is possible to exceed 10m, but the connection quality of this distance is not guaranteed
6. After pairing, when the full duplex serial port is used, it does not need to know any Bluetooth protocol. It supports 8-bit data bits, 1-bit stop bits, and can set the communication format of parity, which is also the most commonly used communication format, and does not support other formats.
7. You can set parameters and query information in at command mode by pulling up 34 feet.
8. Small size (3.57cm * 1.52cm), factory patch production to ensure patch quality. And a transparent heat shrinkable tube, dust-proof beautiful, and has a certain anti-static ability.
9. Switch to the master or slave mode through at command, and connect to the specified equipment through at command
10. Support standard baud rate from 4800bps to 1382400bps

1.4 Product use:
After pairing, it only needs to be used as a fixed baud rate serial port, so as long as the serial port device in the communication format of "fixed baud rate, 8-bit data bit, no parity" can directly replace the original wired serial port without modifying the program. Such as data acquisition, smart car, serial printer, outdoor dot matrix strip screen control, etc.
Pairing with computer: it is suitable for communication between computer and equipment through Bluetooth serial port, and the use method is the same as serial port
Pairing with mobile phone: it is suitable for communication between mobile phone and device through Bluetooth serial port, and the use method is the same as serial port
Pairing with Bluetooth host: it is suitable for two devices to communicate directly through Bluetooth serial port, such as between single-chip microcomputer and single-chip microcomputer, between wired serial port and single-chip microcomputer, etc. the use method is the same as serial port

Flexible use:
Baud rate conversion, because the receiving end and the sending end can choose their baud rates, when the amount of data is small, they can be used as baud rate conversion equipment.
