And controlling pairing of the profile except for the basic profile when the communication module set to the slave module is changed to the master module. 19. The method of claim 18,
A sound input unit for receiving a voice of a user when performing a call function of the terminal;
And a speaker for outputting a voice of the other party when performing a call function of the terminal. 12. The method of claim 11,
Further comprising a speaker outputting an audio signal for an audio function of the terminal. The communication module of any one of the first communication module and the second communication module having the Bluetooth communication method is set as a master module,
The first communication module and the second communication module set the other communication module as a slave module,
A pair of the first group of profiles between the communication module set as the master module and the terminal,
Controlling pairing between the communication module set as the slave module and the terminal through the profile of the second group,
And controlling communication with the terminal by changing a communication module set as a slave module to a master module if communication between the terminal and a communication module set as a master module is impossible. 23. The method of claim 22, wherein setting the master module and the slave module comprises:
Setting a first communication module among the first communication module and the second communication module as a master module,
And setting the second paired communication module as a slave module. 23. The method of claim 22,
A pairing via a general access profile (GAP), a hands-free profile (HFP) and an audio video remote control profile (AVRCP), an advanced audio distribution profile (A2DP), and a phonebook profile (PBAP) Lt; / RTI >
Further comprising controlling pairing via a general access profile (GAP), a hands-free profile (HFP), and an audio video remote control profile (AVRCP) between the communication module set as the slave module and the terminal. 23. The method of claim 22, wherein setting the master module and the slave module comprises:
Setting a predetermined communication module among the first communication module and the second communication module as a master module and setting another communication module as a slave module.
