Electronic device and method for short range wireless communication in electronic device
First Claim
1. An electronic device comprising:
- a communication unit configured to communicate with a cover connected to the electronic device through short range wireless communication; and
a controller,wherein the controller is configured to;
determine generation of an event related to the cover;
supply power to the cover through wireless communication when the event is generated;
make a control to transmit event information to the cover through the short range wireless communication to display the event information on the cover when the cover is driven by the supplied power;
calculate an operation time for the cover to complete display of the event information by analyzing the event information;
when the calculated operation time has passed, determine that the cover has completed displaying the event information; and
switch to a standby mode after releasing a communication connection of the short range wireless communication with the cover when the cover has completed displaying the event information.
