Function Documentation

◆ sl_bt_gap_set_privacy_mode()

sl_status_t sl_bt_gap_set_privacy_mode ( uint8_t  privacy,
uint8_t  interval 

Enable or disable the privacy feature on all GAP roles. New privacy mode will take effect for advertising next time advertising is enabled, for scanning next time scanning is enabled, and for initiating on the next open connection command.

When privacy is enabled and the device is advertising or scanning, the stack will maintain a periodic timer with the specified time interval as a timeout value. At each timeout, the stack generates a new resolvable private address and uses it in scanning requests. For advertisers, the stack generates a new resolvable or non-resolvable private address and uses it in advertising data packets for each advertising set if its address is not application-managed, i.e., the address was not set by the application (with the sl_bt_advertiser_set_random_address command). The application is fully responsible for application-managed advertiser addresses. For an application-managed resolvable private address, the application should schedule periodic address updates for enhancing the privacy. It is recommended to use different schedules for different advertising sets.

Disabling the privacy during active advertising or scanning is not allowed.

By default, privacy feature is disabled.

  • 0: Disable privacy
  • 1: Enable privacy
[in]intervalThe minimum time interval between a private address change. This parameter is ignored if this command is issued to disable privacy mode. Values:
  • 0: Use default interval, 15 minutes
  • others: The time interval in minutes
SL_STATUS_OK if successful. Error code otherwise.

◆ sl_bt_gap_set_data_channel_classification()

sl_status_t sl_bt_gap_set_data_channel_classification ( size_t  channel_map_len,
const uint8_t *  channel_map 

Specify a channel classification for data channels. This classification persists until overwritten with a subsequent command or until the system is reset.

[in]channel_map_lenLength of data in channel_map

This parameter is 5 bytes and contains 37 1-bit fields.

The nth field (in the range 0 to 36) contains the value for the link layer channel index n.

  • 0: Channel n is bad.
  • 1: Channel n is unknown.

The rest of most significant bits are reserved for future use and must be set to 0.

At least two channels shall be marked as unknown.

SL_STATUS_OK if successful. Error code otherwise.

◆ sl_bt_gap_enable_whitelisting()

sl_status_t sl_bt_gap_enable_whitelisting ( uint8_t  enable)

Enable or disable accept list filtering. The setting will be effective the next time that scanning is enabled. To add devices to the accept list, either bond with the device or add it manually with sl_bt_sm_add_to_whitelist.

[in]enable1 enable, 0 disable accept list filtering.
SL_STATUS_OK if successful. Error code otherwise.
