https://devzone.nordicsemi.com/f/nordic-q-a/107910/aoa-direction-finding-sync-delete-disableI&#39;m working on an application with the NRF52833 as an AoA receiver. My application requires that I am able to enable the scanner for a set period of time and then stop scanning. I have an initial AoA dev/demo set up that is working relatively well withen-USTelligent Community 13Wed, 31 Jan 2024 12:53:08 GMThttps://devzone.nordicsemi.com/thread/466934?ContentTypeID=1Wed, 31 Jan 2024 12:53:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a425ded6-07a6-49d5-8173-109a99da2538Simonr<p>Hi Dan</p> <p>Using the&nbsp;<span><strong>bt_le_per_adv_sync_delete</strong>() is perfectly fine/correct to delete/terminate/cancel an ongoing advertising sync object. I guess instead of deleting the sync, you can disable receiving periodic advertiisng reports for a sync with&nbsp;</span><span><span><strong>bt_le_per_adv_sync_recv_disable</strong> and reenable said sync with&nbsp;</span></span><strong>bt_le_per_adv_sync_recv_enable</strong> when necessary. That might be a cleaner option for you perhaps?</p> <p><span>Best regards,</span></p> <p><span>Simon</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/466837?ContentTypeID=1Tue, 30 Jan 2024 19:29:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6201cd08-5c57-4816-9ac4-a007507bb8dedsweet<p>After further debug I found a bug in my code that caused me to skip waiting for the sync callback to occur before proceeding to calling&nbsp;<span>bt_df_per_adv_sync_cte_rx_enable(), which is why I was getting -EINVAL due to a missing sync.</span></p> <p><span>&nbsp;</span></p> <p><span>That said, is deleting the sync with&nbsp;</span>bt_le_per_adv_sync_delete() the correct method for terminating an ongoing sync or is there a better/cleaner way to do this?</p><div style="clear:both;"></div>
