METHOD AND DEVICE FOR PERFORMING BLE CONNECTION FOR WIRELESS CHARGING IN WIRELESS POWER TRANSMISSION SYSTEM

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.
