current connection interval

[Jim]

       I am now based on nrf52832 SDK14.2 development, as a slave, when nrf52832 and mobile phone Bluetooth link, I want to know the current connection interval, how can I obtain?
      Now what I already know is that the maximum and minimum link interval can be known in the "BLE_GAP_EVT_CONN_PARAM_UPDATE" event, but the actual connection interval cannot be known

The application can use both the connection event and connection parameter update event to fetch the current connection parameters. In this case the min interval equal the current interval.

Best regards,
Kenneth
