The link protocol is not responsible for retransmissions; it tells you
if an ack has been received and it is up to your protocol to decide
whether to retry or drop the packet.

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.
