Hi Andrea -
You cannot specify a subset of nodes to send a packet to without programming in your own logic (i.e. deliver the packet to the broadcast address and include the list of addresses that should accept the packet within the payload). The AM_BROADCAST_ADDR is the address to use when you want a packet to get delivered to more than one node. Please send questions to tinyos-help@millennium.berkeley.edu -David _____ From: Andrea Maestrini [mailto:[EMAIL PROTECTED] Sent: Friday, July 11, 2008 12:34 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: multicast messages Hi to all! I 'm new in TinyOS world and I have read the TEP 126 CC2420 RAdio Stack and TinyOS 2.0 tutorial and I have a doubt....I have a simple question for you: - How to send a packet to a group of nodes but not to all of them? I can do broadcast "AM_BROADCAST_ADDR" and unicast "by specifying the node address" but how to do multicast in AMSend.send( ) ? In TinyOS 2.0 Can I do multicast comunication? Thanks for your help!
