[Tinyos-devel] Unified radio HIL

Hi,

I have been using using TinyOS 2.x quite heavily for the past 6 month.
There is a lot of excellent thing, and pretty solutions. However there
is things that can be improved, and are the design choice is not clear
for me.
Most eye-catching, for me, is the absence of unified HIL/HAL for radio
chips. There are four radio chip implementations each of them
implementing custom packet, IEEE 802.15.4, link and so on.
Therefore, for example, implementing unified MAC is not possible
without getting hands-on physical layer.
Almost all of these radio chips are PHY IEEE 802.15.4 compatible.
Therefore it would be nice to have the unified PHY HIL. For the chips
that have extra futures it would be possible to provide additional
interface and the futures would not be waisted.
Is there any plans for the unified radio HIL?

Regards
Laurynas
