In these examples we discover the 128 bit UUID NUS service.&nbsp;</p> <p>Note that you expected to know the UUID of the service and you feed that to the db_discovery module before&nbsp;doing service discovery.&nbsp;</p> <p>If you don&#39;t know the UUID and want to do generic discovery (discovery any UUID) it would be more complex. The library doesn&#39;t support that and you will need to write your code to do so manually.&nbsp;</p><div style="clear:both;"></div>
