hello,all
    i need to turn on and off Radio periodly. but when i turn off the radio, the
timer is stopped.
    i use Micaz motes, some people said it was a bug of Micaz.
    but someone has implemented radio on /off on Micaz ,such as SCP
    is there anyone who can tell me how i can implement so?
    if anyone can give me some advice, it will be highly appreciated!
    Look forward to your reply, thanks!
