Abstract: Disclosed is a method for quickly and conveniently establishing a connection between a master terminal and a slave device communicating with each other using Bluetooth. The slave device implements a special direct connection mode in which the slave device can be directly connected to the master terminal. When a user operates the slave device, the direct connection mode can be selected. The slave device notifies the master terminal of the direct connection mode. The master terminal establishes the direct connection with the slave device through paging without a slave address selection process. Since the direct connection with a target slave can be established without an address selection process, a time required for establishing a connection between the master and the slave can be significantly shortened, and also, the number of process steps can be reduced.
