Abstract: A frequency hopping communication method for short-distance wireless communication between a primary device and a secondary device comprises switching by the primary device from the second frequency hopping sequence to the first frequency hopping sequence at a time point of frequency hopping switching, wherein M reserved channels are between a first frequency hopping sequence and a second frequency hopping sequence; and performing frequency hopping communication with the secondary device based on the first frequency hopping sequence.

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.

Abstract: This application provides a low-power-consumption control method and a short-range wireless communication chip, and belongs to the field of short-range wireless communication technologies. The method includes: obtaining actual received signal strength indications corresponding to a plurality of historical receive slots; predicting, based on the actual received signal strength indications corresponding to the plurality of historical receive slots, received signal strength corresponding to a current receive slot; and adjusting a gain coefficient of a receive channel in a radio frequency front-end module in the current receive slot based on a predicted received signal strength indication. The radio frequency front-end module is coupled to the short-range wireless communication chip.
