Remote control, electronic apparatus and pairing method thereof

An electronic apparatus, comprising:

• a speaker;
• a communicator comprising communication circuitry configured to, based on a first advertising packet being received from a remote control apparatus, transmit a second advertising packet including an address of the electronic apparatus;
• and
• a processor configured to, based on a third advertising packet including a sound output request and the address of the electronic apparatus being received from the remote control apparatus through the communicator in response to transmission of the second advertising packet, output sound through the speaker in response to reception of the third advertising packet, and
• based on a fourth advertising packet including a pairing request being received from the remote control apparatus through the communicator in response to output of the sound, to control the communicator to perform a pairing with the remote control apparatus.

A pairing method of a remote control apparatus, the method comprising:

• transmitting a first advertising packet;
• receiving a second advertising packet including respective addresses of a plurality of electronic apparatuses from the plurality of electronic apparatuses in response to transmission of the first advertising packet;
• and
• determining a priority based on reception characteristic of the second advertising packet upon receiving the second advertising packet;
• transmitting a third advertising packet including a sound output request and an address of an electronic apparatus determined based on the priority from among the received addresses of the plurality of electronic apparatuses;
• and
• based on sound output from an electronic apparatus being received in response to transmission of the third advertising packet, performing a pairing with the electronic apparatus which outputs the sound.
