Wireless power transmitter, wireless power receiver and control method thereof

A control method for receiving charging power from a wireless power transmitter in a wireless power receiver, the control method comprising:

• receiving driving power from a wireless power transmitter;
• transmitting, based on the driving power, an advertisement signal to the wireless power transmitter, the advertisement signal including a handle value and a preset universally unique identifier (UUID), the handle value being used to identify a value assigned to a characteristic in the wireless power transmitter;
• receiving a connection request signal from the wireless power transmitter to establish a communication connection with the wireless power transmitter;
• transmitting static information to the wireless power transmitter over the communication connection;
• and
• receiving a control signal including permission information from the wireless power transmitter.

A wireless power transmitter for transmitting charging power to a wireless power receiver, the wireless power transmitter comprising:

• a communication unit;
• and
• a controller configured to:
• receive, through the communication unit, an advertisement signal from a wireless power receiver, the advertisement signal including a handle value and a preset universally unique identifier (UUID);
• identify a value assigned to a characteristic by adding a predetermined number to the handle value;
• transmit, through the communication unit, a connection request signal to the wireless power receiver for establishing a communication connection with the wireless power receiver, in response to the advertisement signal;
• receive, through the communication unit, static information of the wireless power receiver over the communication connection from the wireless power receiver;
• and
• transmit, through the communication unit, based on the static information, a control signal including permission information to the wireless power receiver.
