https://devzone.nordicsemi.com/f/nordic-q-a/13330/can-i-create-a-simple-ble-application-without-creating-a-serviceHi, I have PCA100040 development board. I need to create two simple ble application. One for central and one for peripheral. How can I do this? Can anyone suggest simple example code? Is it really required to create a service for advertisingen-USTelligent Community 13Wed, 20 Apr 2016 04:58:16 GMThttps://devzone.nordicsemi.com/thread/50813?ContentTypeID=1Wed, 20 Apr 2016 04:58:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:53bdd7b4-d537-4f39-9e8b-f4fe67552860Vikrant<p>Thanks for the help. I tried the beacon example. But when I am scanning from my phone, not able to see any bluetooth device. Does the beacon app really advertise? How do I verify it? Please help.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50812?ContentTypeID=1Tue, 19 Apr 2016 16:37:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c745440a-50b6-40b3-8ed6-19595fe2af9eRK<ol> <li>You start with the example code and adjust it to your needs</li> <li>All the example code in the SDK is about as simple as it gets, I&#39;d say the heart rate service is about the simplest of them all. So understanding the peripheral and central heart rate code would be the best way.</li> <li>No if you <em>just</em> want to advertise and nothing else then you don&#39;t need a service. For that go look at the beacon code, because that&#39;s all a beacon does, it advertises, and has no service.</li> <li>If you don&#39;t need it of course you can remove it, NUS is the service which the NUS service code implements, it sounds like you don&#39;t need it.</li> </ol><div style="clear:both;"></div>
