Electronic device and method for short range wireless communication in the electronic device
Disclosed are an electronic device and a method of short range wireless communication in an electronic device. The method of operating the electronic device may include: when a cover is connected to the electronic device through a short range wireless communication connection, determining generation of an event related to the cover. The method further comprises, when the event is generated, supplying power to the cover through wireless communication, when the cover is driven by the supplied power, transmitting event information to the cover through the short range wireless communication connection to display the information related to the generated event on the cover, and, when an operation of the cover according to the event is completed, switching to a standby mode after releasing the short range wireless communication connection with the cover.
1. An electronic device comprising:
a battery;
a first antenna;
a second antenna;
a short range wireless communication circuit; and
a controller,
wherein the controller is configured to control to:
receive, through the first antenna, wireless power for wireless charging of the battery from an external electronic device,
determine whether an event related to a cover is generated,
based on determining that the event related to the cover is generated, control a strength of the wireless power for the wireless charging of the battery, and
transmit, through the second antenna, information on the generated event to the cover for displaying the information on the generated event on the cover by using the short range wireless communication circuit connected with the cover, while receiving, through the first antenna, the wireless power of the controlled strength for the wireless charging of the battery.
2. The electronic device of claim 1 , wherein the controller is further configured to:
based on determining that the event related to the cover is generated, control the strength of the wireless power to be lower.
3. The electronic device of claim 1 , wherein the controller is further configured to control to:
based on determining that the event related to the cover is generated, deactivate a charging operation of receiving the wireless power for the wireless charging of the battery.
4. The electronic device of claim 1 , wherein the controller is further configured to control to:
supply power from the battery to the cover, and
when the cover is driven by the supplied power from the battery, transmit the information on the generated event to the cover.
5. The electronic device of claim 1 , wherein the controller is further configured to control to:
determine whether another event is generated while the information on the generated event is transmitted to the cover, and
based on determining that the other event is generated, keep transmitting the information on the generated event regardless of the generated other event.
6. The electronic device of claim 1 , wherein the controller is configured to control to:
calculate an operation time for the cover to complete displaying of the information on the generated event by analyzing the information on the generated event, and
when the calculated operation time passes, determine that the cover completes displaying of the information on the generated event.
7. The electronic device of claim 1 , wherein the controller is further configured to control to:
when the electronic device releases a connection of the short range wireless communication circuit connected with the cover and another external electronic device is not recognized, continue supplying power to the cover for a preset standby time.
8. The electronic device of claim 1 ,
wherein the cover is further configured to apply, to a display of the cover, power received from the electronic device.
9. A method for controlling an electronic device, comprising:
receiving wireless power for wireless charging from an external electronic device;
determining whether an event related to a cover is generated;
based on determining that the event related to the cover is generated, control a strength of the wireless power for the wireless charging of a battery; and
transmitting information on the generated event to the cover for displaying the information on the generated event on the cover by using a short range wireless communication circuit of the electronic device connected with the cover, while receiving the wireless power of the controlled strength for the wireless charging of the battery.
10. The method of claim 9 , wherein the controlling of the strength of the wireless power includes:
based on determining that the event related to the cover is generated, controlling the strength of the wireless power to be lower.
11. The method of claim 9 , wherein the controlling of the strength of the wireless power includes:
based on determining that the event related to the cover is generated, deactivating a charging operation of receiving the wireless power for the wireless charging of the battery.
12. The method of claim 9 , further comprising:
supplying power to the cover; and
when the cover is driven by the supplied power, transmitting the information on the generated event to the cover.
13. The method of claim 9 , wherein the transmitting of the information on the generated event to the cover further comprising:
determining whether another event is generated while the information on the generated event is transmitted to the cover; and
based on determining that the other event is generated, keeping transmitting the information on the generated event regardless of the generated other event.
14. The method of claim 9 , further comprising:
calculating an operation time for the cover to complete displaying of the information on the generated event by analyzing the information on the generated event; and
when the calculated operation time passes, determining that the cover completes displaying of the information on the generated event.
15. The method of claim 9 , comprising:
when the electronic device releases a connection of the short range wireless communication circuit connected with the cover and another external electronic device is not recognized, continuing to supply the power to the cover for a preset standby time.
