Hm, you can still use the base operation mode and implement "everything" (i.e., ACK handling, retransmissions etc.) yourself. Hence, the transceiver hardware is capable - it's just a matter of implementation comfort. > Such "extra" feature could only be useful to check how reliable a peer > is, maybe?. True.
