The scanner can be informed of the synchronization information as soon as it receives an ADV_EXT_IND PDU, and then it can later scan only AUX_SYNC_IND PDUs. at this point, is the originally executed scanning mode (e.g., 30/300) still executed? How to realize to scan only AUX_SYNC_IND PDU?If the scanner receives ADV_EXT_IND and gets SyncInfo, and then stops the 30/300 scanning mode and switches the value to synchronous listening mode, how can it support tracking multiple synchronization?
