Does this flag(CC2420_NO_ACKNOWLEDGEMENTS) is used by mac/link layer?
if the CC2420_NO_ACKNOWLEDGEMENTS was set, then no ack will be sent by
receiver, so the receive.Done event will always return true?
thanks
Sam
Tony O'Donovan <[EMAIL PROTECTED]> 写道： When a sender tranmits a message to a
receiver the
receiver can send an acknowledgment (ACK) message. The
purpose of the ACK is to let the sender know the
message was successfully received. If the
CC2420_NO_ACKNOWLEDGEMENTS option is set the receiver
does not send an ACK when it receives a message.
