ble_gap_opt_enable_evt_len_check_t

Enable event length checking.

When this option is enabled, the SoftDevice will prevent the application from switching to a state where the link can utilize more than the configured event length. See ble_gap_conn_cfg_t::event_length . This validation is performed when the application calls the following APIs:

  - @ref sd_ble_gap_connect
  - @ref sd_ble_gap_phy_update

Note

Event length checking is enabled by default.

For a link with an event length of BLE_GAP_EVENT_LENGTH_2MBPS_PHY_MIN , the application cannot connect directly on 1Mbps unless BLE_GAP_OPT_ENABLE_EVT_LEN_CHECK is disabled. The application is allowed to enable this option after the link has switched to 2Mbps.

Return values
