Electronic device and method for outputting alert, and system comprising locking device coupled to electronic device
Various embodiments relate to an electronic device and a method for outputting an alert, and a system comprising a locking device coupled to the electronic device. To this end, the electronic device, according to various embodiments, comprises: a connection terminal; and a processor, wherein the processor is configured to: detect a connection with a locking device via the connection terminal; receive an identifier of the locking device from the locking device; identify the received identifier to set the electronic device in an alert mode; detect a disconnection between the electronic device and the locking device; and output an alert in response to the detected disconnection. Other embodiments may be possible.
1. An electronic device comprising:
a connection terminal; and
a processor,
wherein the processor is configured to:
detect a connection with a locking device via the connection terminal;
receive an identifier of the locking device from the locking device;
identify the received identifier and set the electronic device to an alarm mode;
detect a disconnection between the electronic device and the locking device; and
output an alarm in response to the detected disconnection,
wherein the connection terminal includes a USB type C, and the identifier is received via a configuration channel (CC) pin of the USB type C,
wherein the processor is further configured to:
output the alarm based on a change in a bias voltage level received via the CC pin of the USB type C.
2. The electronic device of claim 1 , wherein the processor is configured to:
determine the electronic device to be a host, based on the connection with the locking device being detected.
3. The electronic device of claim 2 , wherein the processor is configured to:
provide power to the locking device to operate the locking device based on the electronic device being determined to be the host.
4. The electronic device of claim 1 , wherein the processor is configured to:
stop outputting the alarm based on an input for releasing the alarm being received in a state in which the alarm is being output.
5. The electronic device of claim 1 , wherein the processor is configured to:
switch the electronic device to a locking mode based on an input for releasing the alarm being not received for a predetermined time.
6. The electronic device of claim 1 , further comprising a battery,
wherein the processor is configured to:
charge power, supplied via the locking device, to the battery in a state in which the locking device is connected with a charger; and
output the alarm based on the power being not supplied.
7. An alarm output method of an electronic device, the method comprising:
detecting a connection with a locking device via a connection terminal including a USB type C;
receiving an identifier of the locking device from the locking device via a configuration channel (CC) pin of the USB type C;
identifying the received identifier and setting the electronic device to an alarm mode;
detecting a disconnection between the electronic device and the locking device;
outputting an alarm in response to the detected disconnection;
detecting a change in a bias voltage level received via the configuration channel (CC) pin of the USB type C of the electronic device; and
outputting the alarm based on the change in the bias voltage level.
8. The method of claim 7 , further comprising:
determining the electronic device to be a host based on the connection with the locking device being detected.
9. The method of claim 8 , further comprising:
providing power to the locking device to operate the locking device based on the electronic device being determined to be the host.
10. The method of claim 7 , further comprising:
stopping the outputting of the alarm based on an input for releasing the alarm being received in a state in which the alarm is being output.
11. The method of claim 7 , further comprising:
switching the electronic device to a locking mode based on an input for releasing the alarm being not received for a predetermined time.
12. The method of claim 7 , further comprising:
charging power, supplied via the locking device, to a battery of the electronic device in a state in which the locking device is connected with a charger; and
outputting the alarm based on the power being not supplied.
