What's the actual connection interval used?

[Calvin]

Hi,

I'm trying to get the actual connection interval used between my nRF51822 device and iOS device. I have read this article, but I cannot get it worked. I used sd_ble_gap_ppcp_get() function in BLE_GAP_EVT_CONNECTED and BLE_GAP_EVT_CONN_PARAM_UPDATE events, but I always got two different values for max_conn_interval and min_conn_interval. And they were the values I set for MAX_CONN_INTERVAL and MIN_CONN_INTERVAL. Is there any thing I did wrong? Can someone help me to get the actual connection interval?

Thanks and Regards, Calvin

In static void on_ble_evt(ble_evt_t * p_ble_evt), use p_ble_evt->evt.gap_evt.params.connected.conn_params.max_conn_interval to get the actual connection interval in BLE_GAP_EVT_CONNECTED.
