https://devzone.nordicsemi.com/f/nordic-q-a/77281/where-i-can-read-the-service-valueHi, i&#39;m using hte Keil and a custom board with NRF51822. The question is where i can read the value of a custom service? I make the configurations like this tutorial ( http://site.eet-china.com/arrow/technote/Nordic/nan_36_Creating_BLE_Applicatoins_using_nRF51822en-USTelligent Community 13Tue, 13 Jul 2021 11:07:32 GMThttps://devzone.nordicsemi.com/thread/319762?ContentTypeID=1Tue, 13 Jul 2021 11:07:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c9c9cca3-d8f6-45b7-9bde-6aa74653f563Heidi<p>Hi!</p> <p></p> <p>Just to make sure I&#39;m understanding your question: you know that the value of the service should be 0x1110, but when debugging the application, you can&#39;t find this value in Keil?</p> <p></p> <p>A huge portion of the support staff is on summer holiday at the moment so delays are to be expected. I will see if I can find someone with Keil IDE experience to take a look at this.</p> <p></p> <p>Best regards,</p> <p>Heidi</p><div style="clear:both;"></div>
