+        The number of unprocessed advertising report that Bluedroid can save.If you set
+        `BLE_ADV_REPORT_FLOW_CONTROL_NUM` to a small value, this may cause adv packets lost.
+        If you set `BLE_ADV_REPORT_FLOW_CONTROL_NUM` to a large value, Bluedroid may cache a
+        lot of adv packets and this may cause system memory run out. For example, if you set
+        it to 50, the maximum memory consumed by host is 35 * 50 bytes. Please set
+        `BLE_ADV_REPORT_FLOW_CONTROL_NUM` according to your system free memory and handle adv

+        When adv report flow control is enabled, The ADV lost event will be generated when the number
+        of ADV packets lost in the controller reaches this threshold. It is better to set a larger value.
+        If you set `BLE_ADV_REPORT_DISCARD_THRSHOLD` to a small value or printf every adv lost event, it
+        may cause adv packets lost more.
