hi I'm a student and I work on wns, I'm implementing a Mac protocol and I have some unclear concepts, help plz! 1)What is CC2420_TIME_ACK_TURNAROUND? and what is the difference between it and CC2420_ACK_WAIT_DELAY? 2)In my protocol I want to use the preamble, I read in the cc2420 datasheet that there is a physical preamble that its length can't be greater than 4 bytes. But how can I send mac preamble that its length is greater than 4 bytes? 3) how can I enable the software ack and in whitch component are the acknolegements generated ? wait for answers.thx in advance.
