Hi,

The relevant event is BLE_GATTS_EVT_HVN_TX_COMPLETE that will provide the way to check if the the HV Notification data packet has been acked by the peer successfully. You can also increase the queue size for the notifications using ble_gatts_conn_cfg_t::hvn_tx_queue_size so that you are not losing data

Additionally look at the the error code from the function to send the Notifications, you may have been silently losing data.

You can also increase your connection interval if that fits your power envelope.

Take a look at this case that has the events and has a similar question.
