https://devzone.nordicsemi.com/f/nordic-q-a/5729/advertising-with-s120Hi all, Please I want to make sure of something. In the s120 specification, it&#39;s written &quot; Bluetooth low energy combined Central and Peripheral SoftDevice&quot;, and even in the headers files, there is function for advertising (sd_ble_gap_adv_start()) en-USTelligent Community 13Wed, 25 Feb 2015 14:42:20 GMThttps://devzone.nordicsemi.com/thread/20037?ContentTypeID=1Wed, 25 Feb 2015 14:42:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a5fa79af-69e1-49ce-acb8-c6afd9258eecmohBOSS<p>ok, thank you.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/20036?ContentTypeID=1Wed, 25 Feb 2015 14:10:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7c5c961f-fde9-4a64-9356-f157cd419985Hung Bui<p>Hi, The S120 support peripheral role, however, it&#39;s not concurrent with the central role like the S130. If you want to use the S120 with peripheral role you need to enable the softdevice with peripheral role (using sd_softdevice_enable()). Please have a look at sd_ble_enable() function in ble.h header file.</p><div style="clear:both;"></div>
