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, pass-through mode.
[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 host
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 other]
1, using mainstream CSR Bluetooth chip, Bluetooth V2.0 protocol standards.
2, the module supply voltage: 3.3V ~ 3.6V.
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.
8, can STC microcontroller wireless upgrade and download the program.
