A fast connection establishment method for a bluetooth device is used to establish a connection between two bluetooth devices in order to provide a wireless transmission function. A bluetooth module, bluetooth address memory, CPU and connection interface for outside device are installed in each bluetooth device. The method first connects the three signal contacts of a bluetooth device to the three signal contacts of another bluetooth device to interchange the bluetooth addresses with each other. Then, the bluetooth address memory of the bluetooth device is used to store the bluetooth address of the opposite bluetooth device. After this, the bluetooth address is sent out after the power source of the bluetooth device is on. Finally, a bluetooth connection procedure is started if the bluetooth address of the opposite device is received by it in a specific time. Thereby, a wireless transmission can be established between two bluetooth devices.
