A Bluetooth pairing method includes: performing, by a terminal device, encryption computation on a first Bluetooth parameter to generate first pairing information; sending, by the terminal device, the first pairing information to a peer device; and when the terminal device determines that the first Bluetooth parameter is the same as a second Bluetooth parameter, and the peer device determines that the first Bluetooth parameter is the same as the second Bluetooth parameter, determining, by the terminal device, that Bluetooth pairing between the terminal device and the peer device is successful.
