In T1 there was an interface in the radio control modules that allowed one to enable software ACK in the code:
in the config file: // to enable ACK behavior TOSBaseM.MacControl -> RMac; where Rmac is one of: CC1000RadioIntM as RMac, /* mica2 */ /* CC2420RadioM as RMac, /* micaz */ /* there probably is one for telosb, but I didn't use it */ and in your init() or start() code: call MacControl.enableAck(); This forced the message receiver to send a byte back to the sender when it got a good message. The sender could then look at the TOS_Msg.ack field in sendDone() and see if the message went through. Note that this only works for messages that have a specific endpoint, for BCAST messages there is no designated receiver to provide an ACK. You also need to turn this on in you base-station code. If you search this list for ACK and my name you'll probably find this same message, and more...
