Abstract: A method for managing one or more wireless connections includes: conducting a plurality of scan operations and a plurality of connection operations. Each scan operation is conducted within one of a plurality of scan windows, and each connection operation is conducted within one of a plurality of connection windows. The scan windows and the connection windows do not overlap with each other. Consecutive scan windows are separated by a scan interval, which is a first integer multiplication of a minimum interval, and consecutive connection windows are separated by a connection interval, which is a second integer multiplication of the minimum interval. When a new wireless connection is added or an existing wireless connection is removed, the link positions corresponding to wireless connections are adjusted to provide balanced distribution of time slot resource for the wireless connections.
