https://devzone.nordicsemi.com/f/nordic-q-a/14693/nrf51822-beacon-advertisement-functionHello, I have the Beacon Development board and the sample firmware downloaded and up and running in the Keil MDK IDE. My specific application requires some code to execute before the beacon advertisement, so is there a function somewhere that I can inserten-USTelligent Community 13Mon, 27 Jun 2016 15:20:07 GMThttps://devzone.nordicsemi.com/thread/56068?ContentTypeID=1Mon, 27 Jun 2016 15:20:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4e58019e-dd36-4ae8-aed1-be1b3fe4d32eStefan Birnir Sverrisson<p>ok, perhaps I misunderstood your question before. You can use <a href="https://devzone.nordicsemi.com/tutorials/14/">radio notifications</a> to get notification certain time before the advertising event and also when it ends.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/56067?ContentTypeID=1Fri, 24 Jun 2016 20:10:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9545de68-9091-4506-9abb-437bf7dc924dKevin<p>thanks for the quick response! One thing I&#39;d like to do is execute some code at the advertisement interval. Is there some function that is called every time the beacon advertises? Right now, I&#39;m using a timer, but that seems inefficient.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/56066?ContentTypeID=1Fri, 24 Jun 2016 19:46:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5c0983e5-dc6b-4243-aa0a-7454ee9c8b06Stefan Birnir Sverrisson<p>Hi Kevin</p> <p>Open main.c file and find the main function. The beacon_start function starts the advertising so if you want to execute code before starting the beacon advertising, you could place it before the beacon_start call.</p><div style="clear:both;"></div>
