Hi,
We're interested in communicating one node running tinyos-1.x with
another running tinyos-2.x. Physically the platform is the same
(micaz), so the chip radio is the same. I understood tinyos-2.x is
802.15.4 MAC layer compliant, but tinyos-1.x is not. Is that the
reason why the nodes cannot communicate? If we use any IEEE stack
implementation in tinyos1-x, such as modules in contrib directory,
will we be able to communicate the motes?
Thanks

Both are compliant at the link layer. Neither is compliant at the MAC
layer. That is, the packet formats are 802.15.4, but the CSMA isn't.
The major difference between 1.x and 2.x is that 2.x includes layer-2
source addresses in the packets while 1.x does not. If you modified
the 1.x stack slightly to include source addresses (including the
bits in the FCF field), then you should be OK.
