[Tinyos Core WG] [Tinyos-help] problem with AntiTheft with iris

[Janos Sallai]

Phil,

Can we put LPL on the agenda of this week's meeting? There are a couple of things that are unclear in TEP 105 and would be worth a discussion, including
- semantics of AMSend.cancel (when cancel is called, the sender might not be able to decide if the message was received, hence returning ECANCEL is misleading)
- semantics of Packet.clear (what fields does it clear, and what values does it set)
- the default value of rx interval for messages to be sent (is it zero? is it the same as the local rx interval? maybe something else?)
- dummy LPL implementation vs. compile-time error

Janos

Well, they are compatible, they just don't ever try to send packets  
low power. Om and David Moss are looking into incorporating this.
