Implement BR/EDR power mode control with sniff mode functionality. Adds APIs bt_conn_br_enter_sniff_mode() and bt_conn_br_exit_sniff_mode() to manage power saving modes. Includes parameter validation and HCI command handling for sniff mode configuration with min/max intervals, attempt count, and timeout parameters. Signed-off-by: Kai Cheng <[email protected]>
Implement mode change event handling and callback notification for BR/EDR power mode transitions. Adds br_mode_changed callback to notify applications when connection switches between active and sniff modes. Handles HCI mode change events and propagates mode and interval information to registered callbacks. Signed-off-by: Kai Cheng <[email protected]>
Add shell command for testing BR/EDR power mode control. Supports entering sniff mode with configurable parameters (min/max interval, attempt, timeout) and exiting back to active mode. Provides real-time feedback on mode change requests and status. Signed-off-by: Kai Cheng <[email protected]>
