To address privacy concern, the BLE peripheral device is design adverting using RPA without previous pairing/bonding withten-USTelligent Community 13Fri, 04 Nov 2022 11:39:03 GMThttps://devzone.nordicsemi.com/thread/394127?ContentTypeID=1Fri, 04 Nov 2022 11:39:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:abad7011-0f0a-4770-9684-4f860e553430Hung Bui<p>Hi Ge Wang,</p> <p>Could you please let me know the issue you have now with the central connecting to the peripheral running RPA address ?&nbsp;</p> <p><br />I don&#39;t see any problem for a central to connect to an advertiser with RPA address. The only limitation is that the central can&#39;t recognize the advertiser/peripheral when connecting next time because the address may change and without an IRK it can&#39;t recognize that it has previously connected.&nbsp;<br />Other than that you shouldn&#39;t have any problem connecting.&nbsp;</p><div style="clear:both;"></div>
