Abstract: This application provides a spread spectrum clock negotiation method, and a peripheral component interconnect express device and system, to implement dynamic negotiation between a transmit end and a receive end on an SSC capability in the peripheral component interconnect express system. The method includes: A second PCIe device generates first indication information, where the first indication information is used to indicate whether the second PCIe device has a spread spectrum clock capability. The second PCIe device sends the first indication information to a first PCIe device. The first PCIe device determines, based on the first indication information, whether to perform spread spectrum clock on a reference clock of the first PCIe device.

Abstract: A method for periodically measuring blood oxygen saturation is disclosed. The electronic device includes a red light R path and an infrared light IR path, and the R path and the IR path each include a light emitting source and a photoelectric detector. The method includes: The electronic device receives a first instruction indicating to periodically measure blood oxygen saturation; performs, in response to the first instruction, dimming in a first blood oxygen measurement period if a user changes from a non-sleep state to a sleep state, where the dimming is used to determine that a light emitting power of the light emitting source of the R path and a light emitting power of the light emitting source of the IR path are respectively a first power and a second power.

Abstract: The present invention provides a Bluetooth connection management method, a master Bluetooth device, and an apparatus. The method is applied to a scenario in which a master Bluetooth device has established a Bluetooth connection to a slave Bluetooth device. The method includes: determining, by the master Bluetooth device, whether data is being transmitted with the slave Bluetooth device by using the Bluetooth connection; and disconnecting, by the master Bluetooth device, the Bluetooth connection to the slave Bluetooth device when the master Bluetooth device determines that no data is being transmitted with the slave Bluetooth device by using the Bluetooth connection. A user does not need to manually disconnect the Bluetooth connection. So that another master Bluetooth device may establish a Bluetooth connection to the slave Bluetooth device. This avoids a waste of resources.
