Yesterday I picked up TinyOS and spent most of the day getting the environment running. Today I started working with NesC and experimenting with tutorial code. I got radio communication running between telosb motes. I started working with with a set of tinynodes to try and establish radio communication, but have run into a problem where the older v1.1 node will send and receive packets, but the v1.2.1 nodes will not receive packets. So far I haven't been able to determine the difference between the node revisions, and don't know why Rx fails. Specifically, the receive event of the two interfaces I tried (Receive and Snooper) fails to fire, even though both active nodes succeed in sending packets out.
