But as mentioned in the API documentation, the way to work around this is to update the existing set.&nbsp; You can for instance do this by setting up a repeated timer (the low power app timer module is suitable for this purpose) that periodically restarts advertising. Alternatively, instead of the app timer,&nbsp; you could use a shorter adv. duration then use the generated timeout event to trigger advertising start with a new paramaters.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
