[Tinyos-help] Acks on application BaseStationCC2420

[Shuo Xiao]

Hi everyone,

I'd like to add the acks function on application BaseStationCC2420 in tinyos 
2.0 (and I used micaz platform). That is to say, one mote sends packets to 
the BaseStation by radio link, and then PC connecting to BaseStation 
displays packets of the BaseStation by serial link. In the meantime, the 
BaseStation sends acks back to the sender mote by radio link.

I tried to call the command "RadioSend.send"  in the event 
"RadioReceive.receive", which manually sent packets to acknowledge previous 
packets. Can I use interface PacketAcknowledgements in this application to 
implement acks function and how? And the implementation of interface 
PacketAcknowledgements actually sends back ack packets without payload, 
complying with IEEE 802.15.4, am I right?

Thanks a lot

Shuo
