There is provided a link connection method between communication terminals equipped with Bluetooth wireless devices. To automatically connect a link with a communication terminal equipped with a Bluetooth wireless device acting as a slave by Bluetooth wireless communication, a communication terminal equipped with a Bluetooth wireless device acting as a master transmits a link connection request message to the slave upon request of a link connection with the slave. Then, the master determines whether the link is connected and if the link is not connected, transmits the link connection request message as many times as a predetermined number of automatic link connection attempts until the link is connected.
