Without the floor, HC-05, master-slave integrated Bluetooth serial
module, Bluetooth to serial.
Absolutely genuine, support master-slave one, available from AT
command to switch the master.
The most powerful function!
HC-05 is a master-slave integrated Bluetooth serial module can be
switched from the main instruction, instruction rich range (supply
voltage of 3.3V ~ 3.6V)
Host: used to search from the device, other devices can not be
searched. (With white spots Bluetooth module)
Slave: the device used to being searched, you can not take the
initiative to search for other devices.
After connecting the master and slave is equivalent to a serial
line to use, regardless of the Lord from this time on, that is,
[This module can be set to master or slave, the master and slave
pair can communicate between the slave and from the host machine or
Can not communicate between, from the Bluetooth function and
computers, mobile phones and other communication pairing, the
default is to buy from local]
[Note: HC-05 and 06 from the host machine can be paired with each
1, using mainstream CSR Bluetooth chip, Bluetooth V2.0 protocol

3, the default parameters: 9600 baud, pairing code 1234 slave mode.
4, the size of the core module: 27mm x 13 mm x 2mm.
5, the working current: pairing: 30 ~ 40mA paired not
communicating: 2 ~ 8Ma communication: 8mA no sleep.
6, the communication distance: under open conditions 10M, normally
about environmental 8M.
7 for GPS navigation systems, utility meter reading systems,
industrial control systems mining site can be seamlessly connected
with the Bluetooth laptop computer plus a Bluetooth adapter, PDA
and other devices.
