The peer has a service with a custom 128-bit UUID. I am initializing the service like this:

It was nothing related to the service discovery. It was about the way I was handling the notifications of the service.&amp;nbsp;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;span&gt;Thank you very much for your time&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Service not discovered at peer.

&lt;p&gt;The full UUID of the service is: 23434100-1fe4-1eff-80cb-00ff78297d8b&lt;br /&gt;The&amp;nbsp;16-bit address of the service is&amp;nbsp;0x4100&lt;br /&gt;&lt;br /&gt;The full UUID of the characteristic (don`t know it is really relevant here) is:&amp;nbsp;&lt;span&gt;23434101-1fe4-1eff-80cb-00ff78297d8b&lt;br /&gt;The&amp;nbsp;16-bit address of the characteristic is 0x4001&lt;br /&gt;&lt;br /&gt;Thanks&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Service not discovered at peer.

&lt;p&gt;Looking at your code snippets I do not see any obvious errors (this looks very much like the LBS client implementation in the SDK, which is a good reference for a simple custom service client -components/ble/ble_services/ble_lbs_c/ble_lbs_c.c).&lt;/p&gt;
&lt;p&gt;Could there be a problem with the UUID, either the&amp;nbsp;16 bit part of the base? Could you post the full UUID of the service so that we can double check that?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
