Abstract: A method and an apparatus for establishing a Bluetooth data channel are provided. In the method, before starting a service in a first mode, a first communications apparatus negotiates with a second communications apparatus to determine a first parameter. The first parameter may be used for establishing a data channel between the first communications apparatus and the second communications apparatus. After starting the service in the first mode, the first communications apparatus sends a first message to the second communications apparatus. The first message is used to request the second communications apparatus to establish the data channel based on the first parameter. According to the foregoing method, before starting the service in the first mode, the first communications apparatus negotiates with the second communications apparatus to determine the first parameter.

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.
