 When nrf51822 is connected via bluetooth LE to an iPhone application, is it possible to check the actual connection interval (between MIN_CONN_INTERVAL = 20ms and MAX_CONN_INTERVAL = 30ms) that is negotiated between the board and the phone?

&lt;p&gt;p_ble_evt-&amp;gt;evt.gap_evt.params.conn_param_update.conn_params.max_conn_interval&lt;/p&gt;
&lt;p&gt;the &amp;quot;conn_param_update&amp;quot; part is important here =)&lt;/p&gt;
&lt;p&gt;Also note: You have to multiply the value with 1.25 to get milliseconds.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Check BLE connection interval</title><link>https://devzone.nordicsemi.com/thread/37645?ContentTypeID=1</link><pubDate>Tue, 10 Nov 2015 11:34:20 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:1cdc5db8-348f-4e95-b4f8-fae3cf55d1f0</guid><dc:creator>Petter Myhre</dc:creator><description>&lt;p&gt;Great!

When you get the BLE_GAP_EVT_CONNECTED event, you can check p_ble_evt-&amp;gt;evt.gap_evt.params.connected.conn_params.max_conn_interval or p_ble_evt-&amp;gt;evt.gap_evt.params.connected.conn_params.min_conn_interval. Both will be equal to the connection interval.&lt;/p&gt;
&lt;p&gt;This is also true when you get the BLE_GAP_EVT_CONN_PARAM_UPDATE event.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
