You need to specify the exact handle and the role you want to control. You don&#39;t need to restart the device, or the advertiser or the connection etc.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/217813?ContentTypeID=1Thu, 31 Oct 2019 15:36:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:880ab56f-0025-4e08-9613-f288e2afd226Rafael<p>the specific point is, do i need to change the TXPOWER directly using the api or the softdevice? Do I need to restart the device every time?</p><div style="clear:both;"></div>
