Hi Janos Thanks for your reply I've already used VoltageC component. I just wanted to know about controlling the mote and to know more about accessing the peripherals. about the power consumption mails you forwarded me to, I found it very informative but could not know how can I determine how much power in my app. I wanted to know when I started the RF by splitcontrol, is it keeps on or goes to sleep when it finish sending or receiving, and if I used splitcontrol.start i have to use splitcontrol.stp to turn the RF off. what command should i use to turn the RF on when sending a message and goes off or (sleep ) when it stops and then on when it receiving. I've attached my app. file to see if the RF still on or what. and how to modify it to implement what I've said.
