https://devzone.nordicsemi.com/f/nordic-q-a/29581/ble-custom-uuidHello Everyone, I have a basic question related to custom BLE service 128-bit UUID. I know the custom ble service base UUID is the &quot;00000000-0000-1000-8000-00805F9B34FB&quot;. and we can use any 16 bit or 32 bit UUID to converted 128-bit UUID by changingen-USTelligent Community 13Tue, 23 Jan 2018 10:37:31 GMThttps://devzone.nordicsemi.com/thread/117562?ContentTypeID=1Tue, 23 Jan 2018 10:37:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e274add9-8ffb-4212-b3a1-d77f450b8fadBj&#248;rn Kvaale<p>See <a href="https://devzone.nordicsemi.com/tutorials/8/">this services tutorial</a> too for help.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/117563?ContentTypeID=1Fri, 19 Jan 2018 06:21:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cd971739-adb1-4b57-9f8d-ad92b8035accedmond.yun<p>Hello, Jitendra,</p> <p>I think that you need to study or refer the detailed information related with Custom service.... please refer below,</p> <p><a href="https://github.com/bjornspockeli/custom_ble_service_example">github.com/.../custom_ble_service_example</a></p> <p>you can find all that should know the knowledge to make custom service including vendor specific uuid, and we can create the code and UUID automatically with ble studio, it is another method to implement the custom service with custom UUID, please refer below,</p> <p><a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.tools%2Fdita%2Ftools%2Fnrfutil%2Fnrfutil_settings_generate_display.html">infocenter.nordicsemi.com/index.jsp</a></p> <p>thanks.</p><div style="clear:both;"></div>
