https://devzone.nordicsemi.com/f/nordic-q-a/15075/ble-service-discoveryDear all, I&#39;m a quite new BLE stack user and need to get some idea on the idea behind service discovery. I&#39;m using the S130 and the BLE central example and want to read the services and the corresponding characteristics of a peripheral.

If you miss higher protocol layers such as ATT/GATT/GAP you should go back to introduction articles about BT Smart (BLE) as such (there are many sources on the internet nowadays, I always recommend <a href="https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=228441">this original presentation by BT SIG from 2010 during official introduction of LE as part of BT 4.0</a>, member login required but registration is for free).</p> <p>Cheers Jan</p><div style="clear:both;"></div>
