Abstract: A short-distance wireless communication method includes a sending device that sends first clock information to a relay device, where the first clock information indicates a local clock of the sending device, and communication between the sending device and a receiving device is performed based on at least the first clock information. The sending device sends first service data to the receiving device via the relay device. In this manner, the relay device can relay and amplify BLUETOOTH information to increase a transmission distance, and ensure that a frequency hopping sequence, physical layer modulation and bandwidth, and an encryption mode remain unchanged before and after a host is transferred, to ensure a service to be continuously performed and avoid freezing.
