The HC-05 bluetooth module can be set as a transmitter or receiver. You can combine this bluetooth module with your system: MCU, ARM or DSP systems, SOC systems. This module can build a connection to other modules in two ways: as a master or as a slave. Ex, a robot can be designed to be a master connected to a slave bluetooth module or as a slave board to make a wireless connection with a PC.
