https://devzone.nordicsemi.com/f/nordic-q-a/8170/where-to-get-timeslot-scadvHi, I want to use the following project to build a ble scanner which listen on one specific channel: github.com/.../nRF51-multi-role-conn-observer-advertiser Looking at the dependency file, I see I need headers, that should be located in &quot;./nrf51_sdk_v6_0_0_43681en-USTelligent Community 13Tue, 04 Aug 2015 07:17:04 GMThttps://devzone.nordicsemi.com/thread/29362?ContentTypeID=1Tue, 04 Aug 2015 07:17:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:af53fada-8e06-45dd-ba1c-c7decce14e42Thorbjoern Mumme<p>Sorry for the late answer, I was on vacation for the last weeks. Thank you for your patience, I really don&#39;t know why i did not clone the whole project, I just copied the observer part.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/29361?ContentTypeID=1Wed, 15 Jul 2015 06:40:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:969952d8-0176-4471-bf2c-9747eeb46cdb&#216;yvind Karlsen<p>Hi,</p> <p>If you have a look at the dependency file you can see that all the files are subpaths of timeslot-scadv, this means that timeslot-scadv is a folder/directory. Furthermore the header files referenced in the dependency file are all found in the github project, e.g. &quot;folder_name/Include/btle.h&quot;.</p> <p>The idea is that you should clone the github project into Board\pca10001\s110.</p> <p>The file structure has changed from SDK 6 to the current SDK 9, so if things seem unfamiliar that is probably why.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
