https://devzone.nordicsemi.com/f/nordic-q-a/25766/change-advertisement-interval-after-first-connectionUsing SD130 v2.0.1 on nRF51822, I would like to be able to change the advertisment interval after first connection. My app is based on the HRS sample, with a modified avertising_init: static void advertising_init_interval(uint32_t advertIntervalen-USTelligent Community 13Mon, 30 Oct 2017 13:32:34 GMThttps://devzone.nordicsemi.com/thread/101504?ContentTypeID=1Mon, 30 Oct 2017 13:32:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d299c854-bd1b-4b95-a179-13f09973b161Jonathan<p>Yes, you surely can, I didn&#39;t find an appropriate closing reason like &quot;No longer useful&quot; so I didn&#39;t close it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/101503?ContentTypeID=1Tue, 10 Oct 2017 20:13:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:999b971a-3f16-475a-9040-9cd7bcc051bfPetter Myhre<p>Ok.

Seems the thing to do, but wouldn&#39;t work. Might have missed something.

Are you actually doing fast advertising? Not slow? Since this is the interval you are changing.</p><div style="clear:both;"></div>
