HC-08 Bluetooth serial communication module is a new generation of data transmission module based on Bluetooth Specification V4.0 BLE Bluetooth protocol. The wireless working frequency band is 2.4GHz ISM, and the modulation method is GFSK. The large transmitting power of the module is 4dBm, the receiving sensitivity is -93dBm, and it can realize 80m ultra-long-distance communication in an open environment.
The module adopts stamp hole packaging method, which can be patched and welded. The size of the module is 26.9mm×13mm×2.2mm, which is very convenient for customers to embed in the application system.
The module adopts TI's CC2540 chip, configures 256K Byte space, supports AT commands, and users can change the role (master and slave mode), serial port baud rate, device name and other parameters according to their needs. It is flexible to use.
TXD: Serial port transmission, 3.3V TTL level.
RXD: Serial port receiving, 3.3V TTL level.
CTS: Serial port flow control, not currently supported.
RTS: Serial port flow control, not currently supported.
DC: Emulate and burn the clock pin.
DD: Emulation and programming data pin.
RST: Module reset pin, requires a low level of no less than 5ms for reset.
VCC: Module power supply pin, requires a DC 3.3V power supply, and the power supply current is not less than 100mA. Operating voltage range: 2.0V~3.6V.
GND: Module public ground.
LED: Module indicator output pin, high-level output, please connect a resistor in series when connecting to the LED.
Before connecting:
When the host does not record the slave address, it will be on for 100ms per second;
When the host records the slave address, it lights up for 900ms per second;
The slave is on for 1 second every 2 seconds.
After connecting, the LED is always on.
KEY: Input pin, internal pull-down. This pin is connected to a high level for the master to clear the recorded slave address.
