Thanks Philip. I did check on that and corrected some of them already.
I found this to be useful too:
http://enl.usc.edu/~jpaek/porting_tinyos_1_to_2.html
Other than those, I figured out ActiveMessageC is the equivalent of
RadioCRCPacket and we have to use interfaces like Packet,
PacketAcknowledgements too to retrieve some members of message_t.
BUT, I havent figured out how to access CRC of the message. If anyone knows,
pl reply.
Thanks,
Pratibha
