With this, the entire advertising packet will be 31 bytes, which is the maximum. You can refer to this code which is a stripped down version of the beacon example that just use a maximum sized manufacturer specific array (you can drop it into the beacon example in SDK 17.1.0 to test yourself).</p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/0572.main.c">devzone.nordicsemi.com/.../0572.main.c</a></p><div style="clear:both;"></div>
