hi Jan, default MAC for CC2420 is not the IEEE 802.15.4 MAC but in tos/chips/cc2420 there are some interfaces files named cc2420Ieee154Message. what are those? are they wired anywhere? can we replace the default MAC in chips/cc2420 by using these files(cc2420Ieee154Message). means i want to use Ieee 802.15.4 mac layer but don't want to change the csma/ca method by GTS method. thanks.
