The method includes detecting a change of a switching state of a switch of the electronic device, selecting a Bluetooth Device (BD) address according to the changed switching state among a plurality of stored BD addresses, and applying the selected BD address to a Bluetooth pairing. The method can facilitate Bluetooth pairing to selectable types of host devices. ## Claims ### Claim 1 A Bluetooth communication method in an electronic device, comprising: establishing a Bluetooth communication with a first external device by using a Bluetooth address of the first external device;
