HC-05 master-slave one, Bluetooth module, Ar duino wireless Bluetooth serial pass-through module communication
HC-05 Bluetooth module integrated master-slave
With clear buttons
Tips: Do not connect the power supply signals feet, will directly burn module
First, the module parameters:
1.PCB Dimensions: 37.3mm (length) * 15.5mm (W)
(2) Input voltage: 3.6V--6V, 7V ban over
3. Supply anti-reverse, reverse module does not work
4 leads to 6 feet: EN / VCC / GND / RXD / TXD / STATE (Bluetooth status leads to the foot, is not connected to the output low, after connecting output high)
5 with connection status indicator, LED flash means no Bluetooth connection; LED flashing slowly that enter the AT command mode
6 onboard 3.3V regulator chip, the input voltage DC 3.6V-6V; When unpaired, current of about 30mA (because LED lights flashing, the current state of change); After successful pairing, the current is about 10mA
7 Interface level 3.3V, you can directly connect a variety of microcontroller (Arduino/51/AVR/PIC/ARM/MSP430 etc.), 5V microcontroller can also be directly connected. Directly connected to the microcontroller serial port, not through the MAX232 chip!
8 open area effective transmission distance of 10 meters, over 10 meters are possible, but do not guarantee the quality of the connection
9 After the pairing is successful, can be used as a full-duplex serial port. Do not need to know anything about the Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity communication format. This is the most common communication format that does not support other formats!
10 Press the key to give the Bluetooth module is energized to enter AT mode, set parameters and query information
11 can switch the master and slave mode via AT commands
12. Modules default baud rate is 9600, the default passkey is 1234, the default name for the HC-05
13 protection with transparent shrink tube
Second, wiring methods:
VCC: positive power supply
GND: power supply is negative
RXD: Receive side, the Bluetooth module receives data sent to the other device; TXD terminal normally connected to the other device to send
TXD: sending end, the Bluetooth module to send data to other devices; RXD terminal normally connected to other devices receiving
EN: Enable, then you need to enter AT mode 3.3V
