I have a custom 128bit service. I&amp;#39;ve added a bunch of characteristics using characteristic_add(), which end up as 128-bit characteristics according to nRF Connect even though they&amp;#39;re 16 bit e.g. 0x1234 
 How can I make these 16bit?</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 13 Jan 2023 08:49:25 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/95539/add-custom-16bit-uuids-to-custom-128bit-service" /><item><title>RE: Add custom 16bit UUIDs to custom 128bit service</title><link>https://devzone.nordicsemi.com/thread/404735?ContentTypeID=1</link><pubDate>Fri, 13 Jan 2023 08:49:25 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:4e3846e8-65a1-4954-8f69-89b2f54eb2fa</guid><dc:creator>Nick_RA</dc:creator><description>&lt;p&gt;No, that was from another system, it is what I want to match.&lt;/p&gt;

&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;cursor:zoom-in;" alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/4034.old.png" /&gt;&lt;/p&gt;[/quote]
&lt;p&gt;So you somehow got it working here?&lt;/p&gt;
&lt;p&gt;I have only seen this for Bluetooth SIG defined&amp;nbsp;services/characteristics.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Add custom 16bit UUIDs to custom 128bit service</title><link>https://devzone.nordicsemi.com/thread/404118?ContentTypeID=1</link><pubDate>Tue, 10 Jan 2023 14:05:09 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:30d53f00-a6b9-4821-9435-7138f2c0ba28</guid><dc:creator>Nick_RA</dc:creator><description>&lt;p&gt;Maybe some pictures will make my problem clearer: Both are screen captures from nRF Connect&lt;/p&gt;
&lt;p&gt;(ignore the fact the characteristic numbers are actually different here)&lt;/p&gt;
&lt;p&gt;This is what I have, which is as you say:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/0576.new.png" /&gt;&lt;/p&gt;
&lt;p&gt;and this is what I want to match:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/old.png" /&gt;&lt;/p&gt;

&lt;p&gt;The value you passed,&amp;nbsp;&lt;/p&gt;
[quote user=""] e.g. 0x1234[/quote]
&lt;p&gt;is the&amp;nbsp;&lt;span&gt;octets 12-13 of the 128-bit UUID.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
