 We are mass producing NUS-based products. 
 
 During mass production testing, pairing is performed and functionality is tested by pressing buttons, etc. 
 However, pairing takes about 2 to 5 seconds... There are opinions that it takes a long time</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 13 Jun 2024 13:40:22 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/112000/is-it-possible-to-send-and-receive-without-paring-in-nus" /><item><title>RE: Is it possible to send and receive without paring in NUS?</title><link>https://devzone.nordicsemi.com/thread/488698?ContentTypeID=1</link><pubDate>Thu, 13 Jun 2024 13:40:22 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f182f1f5-d536-4915-a35a-bff490c44d36</guid><dc:creator>Kenneth</dc:creator><description>&lt;p&gt;You can for instance try:&lt;/p&gt;

&lt;p&gt;Thanks for the reply.&lt;/p&gt;
&lt;p&gt;I am using the settings as below...&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;#define APP_ADV_INTERVAL 100&lt;/p&gt;
&lt;p&gt;#define MIN_CONN_INTERVAL MSEC_TO_UNITS(20, UNIT_1_25_MS)&amp;nbsp;&lt;br /&gt;#define MAX_CONN_INTERVAL MSEC_TO_UNITS(75, UNIT_1_25_MS)&amp;nbsp;&lt;br /&gt;#define SLAVE_LATENCY 0&amp;nbsp;&lt;br /&gt;#define CONN_SUP_TIMEOUT MSEC_TO_UNITS(4000, UNIT_10_MS)&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I am curious to what extent the above piemeter can be reduced to a line.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;thank&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Is it possible to send and receive without paring in NUS?</title><link>https://devzone.nordicsemi.com/thread/488287?ContentTypeID=1</link><pubDate>Tue, 11 Jun 2024 10:58:09 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:c97d64ee-4dcb-4aba-ad31-7982952d6e81</guid><dc:creator>Kenneth</dc:creator><description>&lt;p&gt;Hello,&lt;/p&gt;
&lt;p&gt;I think I would look at establishing the connection with shorter connection interval and slave latency=0, I don&amp;#39;t know what connection interval you are using today, but using short connection interval (e.g. 7.5ms) will for sure reduce this time. Reducing advertisment interval and increase scanning may also improve the time to establish link.&lt;/p&gt;
&lt;p&gt;Once you have bonded you can for instance do a connection interval update to reduce the connection interval to fit your current consumption requirements.&lt;/p&gt;
&lt;p&gt;Kenneth&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
