Very interesting effort!

No, there is no specification.

Does your serial driver protocol > already specify this kind of things or do you plan them ? Yes, you're right. However the idea is to define an interface, which could be implemented by firmware or by kernel component, responsible for timings. > 3) Which are the IEEE 802.15.4 timing specifications that are really > implemented in your stack ?
