Hi Eric, I have submitted the bug report. Using different channels is definitely a better way to isolate apps than group ids and I will be using that now. Thanks you very much.
Thanks Antonio, for pointing me towards that useful conversation. ________________________________________ From: antonio rosa [[email protected]] Sent: Friday, January 04, 2013 5:40 AM To: Eric Decker Cc: Kumar, Vimal (S&T-Student); [email protected] Subject: Re: [Tinyos-help] Problem with DEFAULT_LOCAL_GROUP on TinyOS 2.1.2 Hi, first sorry for this misunderstanding, I wanted to say that this phenomenon in the BaseStation is due to the Snoop Component, but if the applications nodes does not use the Snoop Component, it must be a filter Group ID. Once years ago, we had the same conversation with this topic: http://www.mail-archive.com/[email protected]/msg39173.html Regards, Antonio Rosa. 2013/1/4 Eric Decker <[email protected]<mailto:[email protected]>> On Fri, Jan 4, 2013 at 12:30 AM, antonio rosa <[email protected]<mailto:[email protected]>> wrote: Hi, about BaseStation, it uses Snoop Component and for that, it snoop all packets, about the node ids, it shouldn't do it. Snoop actually is intended to see all packets (its like a packet sniffer). Are you saying that it shouldn't accept packets that don't match Group? 2013/1/3 Kumar, Vimal (S&T-Student) <[email protected]<mailto:[email protected]>> Hi, I was testing DEFAULT_LOCAL_GROUP on TinyOS 2.1.2 for which I wrote a simple application with two motes bouncing a message back and forth. The motes received each other's message when they had the same group ID but even when they had different group IDs. I set the group IDs in the make file using the DEFAULT_LOCAL_GROUP directive. I can see that the group IDs are set correctly in the transmitted packet but the receiving node does not discard messages with different group IDs. Same thing happens with the BaseStation, which also does not make any distinction between group IDs. Is this a known issue or am I doing something wrong here?
