https://devzone.nordicsemi.com/f/nordic-q-a/4828/s120-and-advertisingHi. I&#39;m doing a project on S120 Softdevice and in &quot;ble_gap.h&quot; file (included from S120 catalog) i have noticed sd_ble_gap_adv_start() command. I tried to use it but i received &quot;NRF_ERROR_NOT_SUPPORTED&quot; error. Is it possible to do advertising with S120en-USTelligent Community 13Mon, 15 Dec 2014 13:07:19 GMThttps://devzone.nordicsemi.com/thread/17071?ContentTypeID=1Mon, 15 Dec 2014 13:07:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5946d4ca-2a91-4b22-bd9b-fda3e9c52c2aMarius Heil<p>I stumbled upon this as well and was irritated at first, because the documentation clearly states that the function should be available. I guess this has to be updated in the documentation as well.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/17070?ContentTypeID=1Mon, 15 Dec 2014 12:00:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1e7bb9b7-f089-4fa5-9585-25e4968e7313David Edwin<p>The S120 does not support the peripheral role required to handle advertising. However you may attempt to use a version of the S120 that supports the time slot API and then <a href="https://github.com/NordicSemiconductor/nRF51-multi-role-conn-observer-advertiser">use this project</a> along with the S120 to do advertising.</p> <p>Please update me on your progress.</p><div style="clear:both;"></div>
