Abstract: Disclosed herein are a Bluetooth connection device and method based on estimation of a relative angle. The Bluetooth connection method based on estimation of a relative angle is performed by a Bluetooth connection device based on estimation of a relative angle, and includes estimating relative angles using relative angle estimation information included in packets received from one or more communication target devices that are scanned for a Bluetooth connection, determining a communication target device with which a communication link is to be established based on the estimated relative angles, and establishing a communication link through a Bluetooth connection to the determined communication target device, and reestablishing the communication link to any one of additional communication target devices, relative angles of which have been estimated, depending on a change in a relative angle to the communication target device with which the communication link has been established.
