Thank you very much Joe!

So, how a protocol sitting on top of BMAC is signaled by the link layer when an Ack has been received?

again with many thanks,
emiliano

I expect that, once Ack is enabled, the packet is sent again up to a maximum number of times. I'm looking inside CC1000RadioIntM to figure where the retransmission of the packet takes place if the Ack is not received but I doesn't understand completely where is the code that invokes a retransmission after an Ack failure.
