Please see MBUS User Manual for details about the repeater functionality embedded in the module. You will see that there is a random delay before repeating the packet to avoid collision. This is also the reason that the repeater stores the incoming packets and repeat them in a random order. It is only SND-IR and SND-NR packets that are repeated.
