establish a third short-range communication connection between the portable communication device and the external electronic device according to the second short-range communication protocol using the information prior to the establishing of the second short-range communication connection.

8. The portable communication device of claim 1 , wherein the short-range communication circuit includes a first short-range communication module to support the first short-range communication protocol, and a second short-range communication module to support the second short-range communication protocol.

9. The portable communication device of claim 8 , wherein the processor is further adapted to:

identify, using the first short-range communication module, that the first short-range communication connection is lost, and

provide the information to the second short-range communication module to be used by the second short-range communication module to establish a third short-range communication connection between the portable communication device and the external electronic device according to the second short-range communication protocol.

10. The portable communication device of claim 8 , wherein the processor is further adapted to:

obtain, using the second short-range communication module, the information as at least part of an outcome of a scan operation.

11. A method comprising:

establishing, at a portable communication device, a first short-range communication connection between the portable communication device and an external electronic device according to a first short-range communication protocol supported by a short-range communication circuit operatively coupled with the portable communication device;

determining whether the first short-range communication connection is lost between the portable communication device and the external electronic device;

obtaining, via a second short-range communication protocol supported by the short-range communication circuit, an advertising packet transmitted from the external electronic device based at least in part on a determination that the first short-range communication connection established according to the first short-range communication protocol is lost, the advertising packet including information corresponding to the external electronic device; and

establishing a second short-range communication connection between the portable communication device and the external electronic device according to the first short-range communication protocol using the information obtained according to the second short-range communication protocol.

12. The method of claim 11 , further comprising:
