Synchronization#

Synchronization.

Provides the base functionality of periodic advertising synchronization. Use bluetooth_feature_sync_scanner and/or bluetooth_feature_past_receiver components to include the synchronization mechanisms that the application requires. Use bluetooth_feature_periodic_sync to include support for trains that do not have subevents or response slots, and/or bluetooth_feature_pawr_sync to include support for Periodic Advertising with Responses (PAwR) trains.

Function Documentation#

sl_bt_sync_set_reporting_mode#

sl_status_t sl_bt_sync_set_reporting_mode (uint16_t sync, uint8_t reporting_mode)
Parameters
[in]sync

Periodic advertising synchronization handle

[in]reporting_mode

Enum sl_bt_sync_reporting_mode_t. Specifies the mode for reporting data received in the periodic advertising train. Values:

  • sl_bt_sync_report_none (0x0): Data received in periodic advertising trains is not reported to the application.

  • sl_bt_sync_report_all (0x1): Data received in periodic advertising trains is reported to the application.

Set data reporting mode of the periodic advertising synchronization.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_sync_update_sync_parameters#

sl_status_t sl_bt_sync_update_sync_parameters (uint16_t sync, uint16_t skip, uint16_t timeout)
Parameters
[in]sync

Periodic advertising synchronization handle

[in]skip

The maximum number of periodic advertising packets that can be skipped after a successful receive.

  • Range: 0x0000 to 0x01F3

  • Default : 0

[in]timeout

The maximum permitted time between successful receives. If this time is exceeded, synchronization is lost. Unit: 10 ms.

  • Range: 0x000A to 0x4000

  • Unit: 10 ms

  • Time range: 100 ms to 163.84 s

  • Default : 1000 ms

Update synchronization parameters for a periodic sync that was already established.

When a sync is established by scanning (see Periodic Advertising Sync Scanner) or by receiving Periodic Advertising Synchronization Transfer (see PAST Receiver), the sync gets the skip and timeout parameters that were configured in the corresponding class. The application can use this command sl_bt_sync_update_sync_parameters to update the values of a sync that has been established. The application can for example update the values to better match the actual interval of the periodic advertising train, or to increase the skip value to minimize wakeups when power saving is prioritized over receiving every periodic advertisement.

Irrespective of the value of the skip parameter, the Controller stops skipping packets if the skipping would cause a timeout.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_sync_close#

sl_status_t sl_bt_sync_close (uint16_t sync)
Parameters
[in]sync

Periodic advertising synchronization handle

Close a periodic advertising synchronization or cancel an ongoing attempt of establishing a synchronization.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

Events

  • sl_bt_evt_sync_closed - Triggered after a periodic advertising synchronization has been closed or canceled.
