   Hi,
   
   There seems to be some misunderstanding about on how extended advertising scan works.
   
   BLE_HCI_EVT_BUF_SIZE defines HCI event size taken from pool, by definition it cannot be larger than 257 (which is probably best value if you have extended scan enabled). 
   
   When you do ext scan and remote is sending big data you'll get fragmented data from nimble and you need to take care of this in your application. This is to avoid caching in stack and keep it simple (at least for time being). data_status field will tell you if more data is expected to come (BLE_HCI_ADV_DATA_STATUS_COMPLETE, BLE_HCI_ADV_DATA_STATUS_INCOMPLETE, BLE_HCI_ADV_DATA_STATUS_TRUNCATED ).
   
   Also, depending on BLE_HCI_EVT_BUF_SIZE or advertiser implementation, you may get data fragmented in any way, so you should make no assumptions about this.
   
   Also, could you please confirm if original issues reported here are fixed?
