1. An electronic device comprising:
- a first short-range communication unit configured to perform a first short-range communication;
a second short-range communication unit configured to perform a second short-range communication with a lower power than that of the first short-range communication unit; and
a controller configured to make a link of the first short-range communication with another electronic device by using the second short-range communication unit,wherein the second short-range communication unit is configured to attempt the second short-range communication with the other electronic device after the link of the first short-range communication is lost, andwherein the controller is further configured to attempt a re-link with the other electronic device through the first short-range communication unit at least partially based on the second short-range communication between the second short-range communication unit and the other electronic device.

Abstract
An electronic device is provided. The electronic device includes a first local area communication part configured to perform a first local area communication, a second local area communication part configured to perform a second local area communication at a lower power than the first local area communication part, and a control part configured to connect the first local area communication to other electronic devices by using the second local area communication part, wherein the second local area communication part may be configured to try a second local area communication with the other electronic devices after the connected first local area communication is disconnected.

14. A method of making a communication link by an electronic device, the method comprising:
-
performing first short-range communication with another electronic device by an electronic device; after a link for the first short-range communication is lost, attempting second short-range communication with the other electronic device by the electronic device, and attempting a re-link for the first short-range communication with the other electronic device at least partially based on a result of the second short-range communication. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. An electronic device comprising:
-
a first communication unit configured to perform communication by using a first communication protocol; a second communication unit configured to perform communication by using a second communication protocol with a lower power than that of the first communication unit; and a controller configured to make a first communication link by using the first communication unit, wherein the second communication unit is configured to attempt a second communication link after the first communication link stops, and wherein the controller is further configured to attempt a re-link with the other electronic device through the first short-range communication unit at least partially based on the second short-range communication between the second short-range communication unit and the other electronic device.
