For large amounts of data with high speed requirements, this is indeed the preferred method. As such, you will need to be sure you do not run your transfer in a blocking loop.

Or just wait with sending next notification until you get BLE_EVT_TX_COMPLETE, which means you have free transmission buffer available. That way you will keep high throughput which would be limited when using indications instead. Indications however make you sure that peer indeed confirmed reception of the packet. BLE_EVT_TX_COMPLETE only informs you that peer received the packet (there is no evident confirmation from the peer).

If you want the app on the phone to say i is successfully received, I think indications is a better option. More info here. That said, you will not lose any packets with notifications, that is, before they are given to the app. The app can ignore the notification, and the peer wouldn't know.
