 I&amp;#39;m using nrf8001 to send twenty 20-byte packets to a phone application. The connection interval I use is 30ms. However, I takes 5 seconds to send the data to the phone. Why is this so? 
 Ideally, it should take around 600ms right? But 5 seconds</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 14 Dec 2018 13:56:29 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/41527/nrf8001-data-sending-time-is-too-long" /><item><title>RE: NRF8001 data sending time is too long</title><link>https://devzone.nordicsemi.com/thread/161878?ContentTypeID=1</link><pubDate>Fri, 14 Dec 2018 13:56:29 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:18b1c5fd-c8c9-448a-9877-f3eae6340b07</guid><dc:creator>run_ar</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;Are you using notifications or indications? Are you making sure you are using all the datacredits?&lt;/p&gt;
&lt;p&gt;We also have a bandwidth test example &lt;a href="https://github.com/NordicSemiconductor/ble-sdk-arduino/tree/master/libraries/BLE/examples/ble_bandwidth_test"&gt;here &lt;/a&gt;that you can use as a reference.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: NRF8001 data sending time is too long</title><link>https://devzone.nordicsemi.com/thread/161489?ContentTypeID=1</link><pubDate>Wed, 12 Dec 2018 14:59:19 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:6d82876c-7d8b-4005-a66d-cdc63263bc09</guid><dc:creator>awneil</dc:creator><description>[quote userid="73112" url="~/f/nordic-q-a/41527/nrf8001-data-sending-time-is-too-long"]the phone[/quote]
&lt;p&gt;What phone?&lt;/p&gt;
&lt;p&gt;Is it different with other phones?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;

&lt;p&gt;Do you mean, &amp;quot;the&amp;nbsp;&lt;span&gt;connection interval I&amp;nbsp;&lt;em&gt;&lt;strong&gt;request&lt;/strong&gt;&lt;/em&gt; is 30ms&amp;quot; ?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Have you confirmed what connection interval is actually being used?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Have you instrumented your code to see what&amp;#39;s happening there?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Have you investigated the phone side&amp;nbsp;to see what&amp;#39;s happening there?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;If you&amp;#39;re on Android, have you looked at the Bluetooth HCI logs?&lt;/span&gt;&lt;/p&gt;
