I&#39;m using nRF51422 dongle with S110 ble_app_uart Connection interval: From this post , it syasen-USTelligent Community 13Mon, 15 Feb 2016 15:21:09 GMThttps://devzone.nordicsemi.com/thread/44978?ContentTypeID=1Mon, 15 Feb 2016 15:21:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d6e7eabf-5e60-46ce-966f-c6a9354a30ceVidar Berg<p>s110 supports up to 6 packets per connection interval as you mentioned, but the actual number will depend on the GAP central. Some Android phones support 6 while others support 4. The connection intervals will also vary.</p> <p>A typical way of obtaining the used parameters is to use a BLE sniffer when in connection with a particular device, same goes for the clock accuracy of the central.</p> <p>Android phones have different BLE chipsets so they don&#39;t all use the same connection parameters. Some parameters may also be affected by the Android version used.</p><div style="clear:both;"></div>
