https://devzone.nordicsemi.com/f/nordic-q-a/36449/send-custom-data-when-advertising-and-don-t-allow-connectionsI want to make a small sensor that will wake up every once in a while, turn on advertising for a second or two and then go back to sleep again. I&#39;m trying to figure out which example should I take a look at if I want my device to be discoverable buten-USTelligent Community 13Mon, 16 Jul 2018 13:33:50 GMThttps://devzone.nordicsemi.com/thread/140221?ContentTypeID=1Mon, 16 Jul 2018 13:33:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d96e43d0-c9c4-4390-ba2b-defab5100025Martin<p>I have made a system like the one you&#39;re talking about, unfortunately it&#39;s under NDA so I can&#39;t share it with you. To get you started I would suggest looking at the ble_beacon example, and also the HRS and HRS Collector examples. You would want to modify the data from the advertising bit of the beacon example to fit your needs. You also need to reinitiate the advertiser with your changed data. Use manufacturer specific data and you should be well on your way ;) For timing i suggest using the Application timer running on the RTC clock. (Look at DevZone or the Infocenter). Hope this helps you.</p> <p>Good luck!</p><div style="clear:both;"></div>
