Abstract: An anti-theft method and apparatus relating to the field of anti-theft technologies, and to reduce costs. The anti-theft method includes obtaining a detection signal from a terminal device, where the detection signal is a signal sent by the terminal device when the terminal device detects an available network, and performs an alarm operation when the detection signal meets a preset condition. The anti-theft method may be applied in daily life in order to ensure family property security.

Abstract: A first device performs periodic scanning alternately, where a first scanning periodicity is used for a first-type Bluetooth connection, and a second scanning periodicity is used for a second-type Bluetooth connection; the first device receives a first-type data packet from a second device in a first scan window of any first scanning periodicity, where the first-type data packet is used to establish the first-type Bluetooth connection; the first device obtains, based on the first-type data packet, a second connection parameter for establishing the second-type Bluetooth connection to the second device; and the first device establishes the second-type Bluetooth connection to the second device based on the second connection parameter.
