[Tinyos-help] changing frequency on the fly does not work even in latest version of T2

[Tie Luo]

platform: micaz, tinyos 2.x (Revision: 1.1.2.22)
I have updated to the latest TInyos delevelop branch.  Although some bug on
switching channels was fixed (release resource after sync()), there are
still problems.
A mote can send message after switching to a new channel, but the other mote
cannot receive the message.
If I change -DCC2420_DEF_CHANNEL to be the new channel, which means both
motes will "switch" from the new channel to the new channel, then the
communication is correct.
In summary, changing channel at compile time works, while changing on the
fly does not.
Do the sync() and syncDone() really work, for both sending and receiving?
