MULTIPLE CONNECTION MANAGEMENT FOR BLUETOOTH LOW ENERGY DEVICES

摘要

Methods and systems are disclosed for multiple connection management for Bluetooth (BT) devices, and more particularly for BT Low Energy (BLE) devices, to multiple different bonded BT peer devices. A BT device database within a non-volatile memory (NVM) stores identification and persistent information for each bonded BT peer device. At power-on reset (PoR), only device identification information (DII) data, such as an address (ADDR) and an IRK (identity resolving key), for each bonded BT peer device is copied from the NVM to a volatile memory that is used for run-time operation. When a bonded BT peer device forms an active connection, it is identified using the DII data, and its persistent data is copied from NVM to volatile memory as run-time data. The BT device then communicates with the actively connected BT peer device at least in part using the run-time data for the actively connected BT peer device.
