Hi,

Is maximum packet size of TinyOS is 32 bytes?Moreover in Surge application 34 byte packet some times. Surge do send the 22 byte packet. What does this packet signify and can any one tell me the packet format?

Look for the actual message packet structures in .h files in the various
application's source directories -- those structs are overlaid on the
Msg.data[] buffer. As to how many variations there are and how they work,

that is a matter of conjecture...google may be your friend here.

T1.1.N all have the same directory and file structure. I would recommend
that you get on the higher .N number side of things, 1.1.7 or greater

if you value your sanity.

I was always alone in this world,
wanted to be loved,by someone.
I always had teary eyes,
wanted it to be wiped by someone.
