 I am using the NUS service and I noticed that Android 6 (Marshmallow) will not go faster that 47.5 ms. Even iOS can go to 30ms. My target is 7.5. 
 Am I doing something wrong? Anyone has some advice?

&lt;p&gt;The minimum connection interval is highly dependent on the hardware present in your mobile phone. Please see &lt;a href="https://devzone.nordicsemi.com/question/3440/how-do-i-calculate-throughput-for-a-ble-link/"&gt;this thread&lt;/a&gt; for some examples. For further information you can see &lt;a href="https://devzone.nordicsemi.com/question/30611/data-rate-measurment/?answer=30753#post-id-30753"&gt;this answer&lt;/a&gt; and the blog on &lt;a href="https://devzone.nordicsemi.com/blogs/32/how-different-ble-packet-types-influence-throughpu/"&gt;how different BLE packet types influence throughput&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;While the nRF family is capable of 7.5 ms connection intervals, most mobile phones are not.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Øyvind&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
