Attribute not found can sometimes be used to know that the end of discovery procedure has been achieved and the app does not need to see to find more attributes after that range.</p> <p>It seems to me that the service/characteristics are not properly initialized or something else went wrong in the server side. It is still not clear to me why you suspect that the highlighted sniffer packet is wrong?</p><div style="clear:both;"></div>RE: 52832 slaver connected by android app but not find servicehttps://test-devzone.nordicsemi.com/thread/370359?ContentTypeID=1Wed, 01 Jun 2022 08:34:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4886a5bd-5aca-4972-ba7b-0a9d73f84296user65627<p>This is the bad connect by sniffer packected, you can find it at end of conn_err.pcapng</p> <p><img src="https://test-devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1654072429866v1.png" alt=" " /></p><div style="clear:both;"></div>
