Abstract
The present disclosure relates to a method of performing a BLE connection for wireless charging in a wireless power transmission system, wherein a wireless power transmitter receives, in a negotiation phase, an ADD packet including a random address from a wireless power receiver. The wireless power transmitter transmits an ACK for the ADD packet to the wireless power receiver and performs advertising on the basis of the random address. The wireless power transmitter establishes a BLE connection with the wireless power receiver.
Claims14
A method for performing, by a wireless power transmitter, wireless charging in a wireless power transfer system, the method comprising:
- receiving a Configuration (CFG) packet from a wireless power receiver in a configuration phase;
- entering a negotiation phase with the wireless power receiver based on the CFG packet;
- wherein in the negotiation phase,
- receiving an address (ADD) packet including a random address from the wireless power receiver;
- transmitting an ACK for the ADD packet to the wireless power receiver and performing an advertisement based on the random address;
- and
- forming a Bluetooth Low Energy (BLE) connection with the wireless power receiver.
A wireless power transmitter in a wireless power transfer system, the wireless power transmitter comprising:
- a converter associated with transmitting or receiving wireless power;
- and
- a communication/controller associated with controlling the transmitting or receiving of the wireless power, wherein the communication/controller is configured to:
- receive a Configuration (CFG) packet from a wireless power receiver in a configuration phase;
- enter a negotiation phase with the wireless power receiver based on the CFG packet;
- wherein in the negotiation phase,
- receive an address (ADD) packet including a random address from the wireless power receiver;
- transmit an ACK for the ADD packet to the wireless power receiver and perform an advertisement based on the random address;
- and
- form a Bluetooth Low Energy (BLE) connection with the wireless power receiver.
