You are right, they both support auto ACK, CSMA-CA, retries and address filtering. They do support beacon-enabled networks in that they can send out slotted auto-ACKs, etc. But in this case, the burden of providing the exact timing falls on the micro-controller. It should pulse a pin to trigger the actual sending of the ACK. This is probably because of the fact that only the stack would know the relevant timings such as slot-boundaries. >> As far as a single radio joining two PANs is concerned, in case the >> aforementioned hardware acceleration is used, it cannot be done, >> unless the radio itself supports dual addresses, pan ids, etc. If such >> a radio does arrive in the market, can we not have two instances of >> wpan phy itself, one bound to each such 'logical' radio? > 76.164.216.197:8181 > > > No, because it would be still a single radio with single channel settings.
