However, for an example of how to build a custom service, I&#39;d recommend you to have a look at <a href="https://www.nordicsemi.com/eng/content/download/34055/573345/file/nAN-36.zip">nAN-36</a>.</p> <p>We don&#39;t have any similar document explaining how to build a GATT Client, but there are some examples in the SDK, mainly ble_ias_c.c and ble_ans_c.c.</p><div style="clear:both;"></div>
