Abstract

A Bluetooth device and a method of searching for a peripheral Bluetooth device using a previous search results are provided. The method of searching for a peripheral Bluetooth device includes: acquiring, if input instructing the start of an initial search is received, initial search address information and initial search device information about at least one peripheral Bluetooth device in a preset period; storing the acquired initial search address information and initial search device information in a storage unit; acquiring, if a request for searching for a peripheral device for performing Bluetooth communication is input, address information of a found peripheral Bluetooth device; determining whether address information corresponding to the acquired address information of the found peripheral Bluetooth device exists in the storage unit; and notifying a user, if address information corresponding to the acquired address information of the found peripheral Bluetooth device exists in the storage unit, of the stored initial search device information of the found peripheral device corresponding to the address information.

Claims21

Dependent claims

A method, operable in a Bluetooth device, for searching for a peripheral Bluetooth device, comprising:

detecting an input instructing the start of a pre-search;
acquiring an initial search address information and an initial search device information about at least one peripheral Bluetooth device in a preset time period through preset channels in which the preset time period is a value set as a time interval in which a state of the at least one peripheral Bluetooth device changes states from a standby state to a wakeup state;
storing a peripheral Bluetooth device list using the acquired initial search address information and initial search device information in a storage unit;
detecting an input requesting a search for a peripheral device that performs Bluetooth communication;
acquiring address information of a found peripheral Bluetooth device through the preset channels;
determining whether address information exists in the storage unit that corresponds to the acquired address information of the found peripheral Bluetooth device;
and
updating the peripheral Bluetooth device list by adding the acquired address information of the found peripheral Bluetooth device when said acquired address information does not exist in the storage unit, or deleting from the peripheral Bluetooth device list address information of the found peripheral Bluetooth device, when address information of the found peripheral Bluetooth device exists in the storage unit and no new address information is acquired that causes update of the address information in the storage unit of the found peripheral Bluetooth device, wherein the updating of the peripheral Bluetooth device list occurs only after expiration of the present time period, or when receive initial search device information is determined to be critical information according to one or more preset criterion values;
and
notifying a user that the stored initial search device information of the found peripheral device corresponds to the address information of the found Bluetooth peripheral device, after determining that address information exists in the storage unit that corresponds to the acquired address information of the found peripheral Bluetooth device.

7 more elements

A Bluetooth device, comprising:

a Bluetooth module for transmitting and receiving signals for acquiring address information and device information of at least one peripheral device through present channels in a preset time period according to a Bluetooth communication protocol in which the preset time period is a value set as a time interval in which a state of the at least one peripheral device changes states from a standby state to a wakeup state;
a storage unit for storing a peripheral device list using the acquired address information and device information;
and
a controller for acquiring, if an input instructing the start of an initial search is received, initial search address information and initial search device information of at least one peripheral device in a preset period, acquiring, if a request for searching for a peripheral device for performing Bluetooth communication is a user input, address information of a found peripheral device, determining whether address information corresponding to acquired address information associated with said found peripheral devices exists in the storage unit,
the controller updates the peripheral Bluetooth device list by adding the acquired address information of the found peripheral device when said acquired address information does not exist in the storage unit, or deleting from the peripheral Bluetooth device list address information of the found peripheral device, when address information of the found peripheral device exists in the storage unit and no new address information is acquired in which the controller is configured for updating of the peripheral Bluetooth device list occurs only after expiration of the preset time period, or when the controller determines that the received initial search device information is determined to be critical information according to one or more present criterion values, notifies a user, if said address information corresponding to the acquired address information of said found peripheral devices exists in the storage unit, of device information of the at least one peripheral device corresponding to the address information.
