I'm not sure if you are referring to the packet type or the encoding, but you are basically correct. If I understand the specifications correctly, the two radios work in different ways. They transmit using different strategies, different radio encodings, and different error correction. Even if they were the same frequency, it would be unlikely that they could talk to each other. The CC2420(Zigbee) chip is also more "intelligent" -- it does some of the processing itself that the CC1000 requires the CPU to do. The Mica uses a different radio yet from the Mica2 and the MicaZ/Telosb/etc. and is completely incompatible with all the others, even at the same frequency. I'm not sure there is a clear table of these differences out there. There ought to be, there are many types of motes on the market, and there should be a quick reference. Does anyone still update a TinyOS wiki? -- The difference between the right word and the almost right word is really a large matter- it's the difference between a lightning bug and the lightning. -Twain _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
