US 12,526,623 B2 · Bluetooth random address generation method and related electronic device

Abstract

This application provides a Bluetooth random address generation method and a related electronic device. The method includes: the Bluetooth Host generates an identity resolving key (IRK); the Bluetooth Host sends the IRK to the Bluetooth module when the electronic device meets a first condition, where the first condition is a condition for triggering the electronic device to reduce power consumption; the Bluetooth module generates a resolvable private address (RPA) based on the IRK, and periodically updates the RPA based on the IRK; the Bluetooth Host sends an RPA request to the Bluetooth module when the Bluetooth Host needs to execute a Bluetooth service; the Bluetooth module sends a latest updated RPA to the Bluetooth Host; and the Bluetooth Host executes the Bluetooth service based on the latest updated RPA. Therefore reducing the power consumption of the AP chip, and extending the standby time of electronic device.
