Can KW40Z BLE send more than one notification per time slot?

I have read that it is possible for a BLE peripheral to send more than one characteristic notification per time slot, thus increasing the bandwidth (e.g. see https://bluegiga.zendesk.com/entries/24646818-Throughput-with-Bluetooth-Smart-technology and https://punchthrough.com/blog/posts/maximizing-ble-throughput-on-ios-and-android ):

 

"When using the non-acknowledged data transmission operation, the Bluetooth Smart technology supports a "bulk transmission of data." This means that multiple packets can be sent in a single connection interval, since there is no need to wait for the acknowledgements to be received. This can enable higher throughput if the Bluetooth Smart radio is able to send multiple packets within a single connection interval".

Is this possible with KW40Z? How many messages can it enqueue and send in a single connection interval?

 

Thank you in advance,

Vito.
