The BLE desktop app was used to configure the dongle. I know that the dongle is working correctly because I can use the nrf connect app on my cell phone to connect to theen-USTelligent Community 13Thu, 14 Jul 2022 14:05:19 GMThttps://devzone.nordicsemi.com/thread/377009?ContentTypeID=1Thu, 14 Jul 2022 14:05:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8a4d5283-8897-4591-b9da-65bb9df5e697Hung Bui<p>Hi Roy,&nbsp;<br />If you have a look at the source code of the central bas application you can find this:&nbsp;<br /><img style="max-height:381px;max-width:625px;" alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/1250x762/__key/communityserver-discussions-components-files/4/pastedimage1657807426140v1.png" /></p> <p></p> <p>So it&#39;s important that the advertiser exposes the BAS service (UUID =&nbsp; 0x180F) in the advertising packet.&nbsp;<br /><br /></p> <p>Without that the central won&#39;t connect or report anything in the log.&nbsp;</p> <p>You can test the central bas with the peripheral mouse for example.&nbsp;</p><div style="clear:both;"></div>
