I am using the recommended scan parameters from the core spec: If I try to start advertising with these parameters (NCS 2.5 with softdeviceen-USTelligent Community 13Mon, 18 Dec 2023 09:12:46 GMThttps://devzone.nordicsemi.com/thread/460749?ContentTypeID=1Mon, 18 Dec 2023 09:12:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a2d11703-b70a-4c81-af85-3af4b22daa75Hung Bui<p>Hi Jonas,&nbsp;<br />Our softdevice controller&nbsp;has different implementation regarding scanning on multiple PHYs that each PHY would has its own scanning window.&nbsp;<br />So to be able to scan on 1Mbps and Coded PHY the following apply (quoted from our internal discussion with R&amp;D team):&nbsp;<br /><em><span dir="ltr">The scan windows have to fit into the scan interval. In the case of scanning on two phys and the same window for both phys, window has to be less than 50% of the interval.</span></em></p> <p>Could you try to&nbsp;reduce the scan windows ?</p><div style="clear:both;"></div>
