ماژول بلوتوث HC-08 - بلوتوث سریال ورژن 4 - تراشه CC2540 Technical Data: TXD: serial transmit, 3.3V TTL level. RXD: serial receiver, 3.3V TTL level. CTS: serial flow control, is not supported. RTS: serial flow control, is not supported. DC: simulation, burning clock pin. DD: simulation, data burning feet. RST: reset pin module requires low level of not less than 5ms reset. VCC: module power foot, requiring DC 3.3V power supply current is not less than 100mA. GND: module common ground. LED: LEDs module output pin, high output, series resistor connected LED. Slave bright one second every two seconds. Once connected, LED lit. KEY:. Input pin, internal pulldown This foot high, clear the record for the host address from the machine. PIO: extended functionality for setting the module master-slave mode, the default internal pull-up resistor from the machine; external 1K pull-down resistor connected to ground, as the host. Currently only supports 9600bps communication, does not support the AT commands. Host, when pass-through traffic from the machine, there must be a certain time interval between packets. For example, the packet length is 500 bytes, then the transmission time interval between packets can be set to no less than 600ms. Otherwise, you may lose data.
