Hey  All,

I've a question. Why TOSH_DATA_LENGTH is set to 28 in Tinyos-2.x? I know that in the previous version was 29. Why not 30, 45, etc??
Is there an article explaining why did they choose this value?.


It was originally 30; then a length field was added and it became 29 in the mica platform. IIRC, it was made 28 in T2 to simplify alignment on 16-bit platforms.

Why 30 originally? Jason Hill once joked he picked it out of the air as something that seemed reasonable. :)
