R: [Tinyos-help] tinyOS 1.x 2.0 interoperability

[Tempia Filippo]

Which files define the 802.15.4 configuration for TinyOS 2.0 and 1.1 so
that I can compare them?
Thanks!

Filippo

The packet formats are different. 802.15.4 has different packet  
formats depending on the bits in the frame control field (FCF). For  
example, there are different source and destination addressing modes,  
encryption, etc. TinyOS 1.x does not have a source address in the  
packet; TinyOS 2.x does. So the packet formats are not compatible.
