Broadcast Multi Transmits

Hi I would like to know what happens when the wake time has passed and “broadcast multi transmits” messages has not finished. Are they going to be send on the next wake?
Also I would like to know the same thing in unicast mode transmissions. When the wake time has passed and for a packet has not received an acknowledgment, will it be re-transmitted in the next wake?If yes how can we avoid to re-transmit in the next wake?

Thanks in Advance
Dimitris

What is the exact product and firmware versions you are referring to?
