Bluetooth Master Device Automatic Pairing for Multiple Slaves

The patent applies preliminary action by pre-grouping multiple Bluetooth slave devices into a device combination before the actual connection process. The master device scans and identifies multiple slave devices as a group, storing their address information in advance. When connection is needed, the system automatically establishes connections with all devices in the group simultaneously, eliminating the need for manual sequential selection and significantly reducing connection establishment time while maintaining reliable connections.

The patent merges multiple individual slave devices into a single device combination entity. Instead of requiring users to select each slave device individually, the system presents the group as one selectable unit. When the user selects the device combination, the system automatically handles the pairing and connection establishment with all individual devices in the group, thereby improving ease of operation while maintaining connection accuracy through automatic address information matching.

The patent segments the Bluetooth connection process into distinct phases: scanning and grouping phase (where multiple slave devices are identified and grouped into a device combination), and connection establishment phase (where automatic pairing is performed with all devices in the group). This segmentation allows the system to manage complexity by handling device discovery and connection establishment as separate, automated processes, improving productivity without overwhelming the user with system complexity.
