Based on the command received, BLE peripheral device should advertise in direct advertising mode for the particular host using its public type address.

It has public <strong>or</strong> private. If it is private you cannot do directed advertising if you haven&#39;t bonded first.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/86876?ContentTypeID=1Fri, 19 May 2017 01:13:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ff44cff5-f0cb-4678-bc55-d02c9c55fbf7Jebakumar<p>Yes. I want to do directed advertising with public address (of host). It means I know the public address of the host peer. I will use this address during directed advertising. But what if the host uses private resolvable address (while I use host&#39;s public address instead of its private resolvable address during directed advertising) ?</p> <p>If the above status doesn&#39;t work then there is no way to do directed advertising with the un-bonded host which is using private resolvable address instead of its public address. right?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/86875?ContentTypeID=1Thu, 18 May 2017 12:18:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9e4ad9df-2148-4dee-bb6b-aeedf9db49ddPetter Myhre<p>I don&#39;t understand. Do you want to do directed advertising against devices with public addresses or private resolvable addresses?</p><div style="clear:both;"></div>
