  • HC-05

    The HC-05 is a class 2 Bluetooth module designed for transparent wireless serial communication. It is pre-configured as a slave Bluetooth device. Once it is paired to a master Bluetooth device such as PC, smart phones and tablet, its operation becomes transparent to the user. No user code specific to the Bluetooth module is needed at all in the user micro-controller program. The HC-05 supports two work modes: Command and Data mode. The work mode of the HC-05 can be switched by the on-board push button. The HC-05 is put in Command mode if the push button is activated. In Command mode, user can change the system parameters (e.g. pin code, baud rate, etc) using host controller itself of a PC running terminal software using a serial to TTL converter. Any changes made to system parameters will be retained even after power is removed. Power cycle the HC-05 will set it back to Data Mode. Transparent UART data transfer with a connected remote device occurs only while in Data Mode. The HC-05 can be re-configured by the user to work as a master Bluetooth device using a set of AT commands. Once configured as master, it can automatically pair with a HC-05 in its default slave configuration or a HC-06 module, allowing a point to point serial communication. The HC-05 will work with supply voltage of 3.6VDC to 6VDC, however, the logic level of RXD pin is 3.3V and is not 5V tolerant. It can be damaged if connect directly to a 5V device (e.g Arduino uno and Mega). A Logic Level converter is recommended to protect the HC-05. The power to the HC-05 will cut off if the "EN" pin is pulled to logic 0.

  • HC-06

    HC-06 is a class 2 slave Bluetooth module designed for transparent wireless serial communication. It is only a slave device unlike the hC-05 which can act as a Master/Slave. This means the HC-05 can initiate a connection to another device and the HC-06 can only accept a connection from another device. Once it is paired to a master Bluetooth device such as PC, smart phones and tablet, its operation becomes transparent to the user.The HC-06 will work with supply voltage of 3.6VDC to 6VDC, however, the logic level of RXD pin is 3.3V and is not 5V tolerant. A logic level converter is recommended to protect the module if connected to a 5V device. 

    The module is suitable where wireless data transmission is needed in slave mode. The board can be accessorized with a USB to TTL serial cable to connect to your PC. Like the HC-05, the HC-06 module can reach a range of up to 9 meters (30 ft). If you need a Bluetooth module to talk to your smartphone and an Arduino board, the HC-06 would work fine whereas if you want to talk with another Arduino development board, HC-05 will be selected.
