Function Documentation#

ble_peer_manager_central_init#

void ble_peer_manager_central_init (void )

Parameters

Type	Direction	Argument Name	Description
void	N/A

Initialize the Peer Manager.

Set default values for scanner, reset filters, set state to IDLE and create an emtpy connection array.

ble_peer_manager_central_set_scanner#

sl_status_t ble_peer_manager_central_set_scanner (sl_bt_gap_phy_coding_t scanning_phy, sl_bt_scanner_discover_mode_t scan_discovery_mode, sl_bt_scanner_scan_mode_t scan_mode, uint8_t scan_interval, uint8_t scan_window)

Parameters

Type	Direction	Argument Name	Description
sl_bt_gap_phy_coding_t	[in]	scanning_phy	PHY to use for scanning.
sl_bt_scanner_discover_mode_t	[in]	scan_discovery_mode	Discovery mode to use for scanning.
sl_bt_scanner_scan_mode_t	[in]	scan_mode	Scan mode to use for scanning (active or passive).
uint8_t	[in]	scan_interval	Scan interval to use for scanning.
uint8_t	[in]	scan_window	Scan window to use for scanning.

Set scanner parameters.

Set the scanner parameters if the Peer Manager is in IDLE state. Call this function before starting the scanner.

ble_peer_manager_central_create_connection#

sl_status_t ble_peer_manager_central_create_connection ()

Create a central connection.

The Peer Manager will start the scanner. If a connection opened event is received, and the connection handle is the same as in the sl_bt_connection_open() function, the Peer Manager will stop the scanner and save the connection.

ble_peer_manager_central_open_connection#

sl_status_t ble_peer_manager_central_open_connection (bd_addr * address, uint8_t address_type)

Parameters

Type	Direction	Argument Name	Description
bd_addr *	[in]	address	Address of the peripheral device.
uint8_t	[in]	address_type	Address type of the peripheral device.

Open a connection as a central.

ble_peer_manager_central_close_connection#

sl_status_t ble_peer_manager_central_close_connection (uint8_t conn_handle)

Parameters

Type	Direction	Argument Name	Description
uint8_t	[in]	conn_handle	Connection handle of the connection which needs to be closed.

Close connection.
