Thanks Ruben for your answer I am trying to make everything clear. because I've read about this many times. Once you call splitcontrol().start and the splitcontrol.startdone event is signalled, the radio stays on. If you send something, the radio goes into TX ( do you mean the RF will be one of the 3 modes TX,RX or Idle ? ) and after the sentdone is signalled it goes back to Listen, is this listen mode differ from lowpowerlistening mode but if you don't send something it stays in Listen-mode, is this listening mode consumes much power ? unless you call splitcontrol.stop() I do not want to call the splitcontrol.stop because I'll receive messages, I just want the mote to work normally with little power consumption by take advantage of the periodes in which the Radio not sending or receiving but without turning it off. how can I work around this if it's not possible Thanks & Have a Nice Day Mohamed --- On Sat, 3/21/09, Ruben Catteeuw <[email protected]> wrote: From: Ruben Catteeuw <[email protected]> Subject: RE: [Tinyos-help] Need your Help: Battery Voltage measurement To: [email protected] Cc: [email protected] Date: Saturday, March 21, 2009, 10:36 AM #yiv1626845292 #yiv889195410 .hmmessage P { margin:0px;padding:0px;} #yiv1626845292 #yiv889195410 { font-size:10pt;font-family:Verdana;} Hi, Once you call splitcontrol().start and the splitcontrol.startdone event is signalled, the radio stays on. If you send something, the radio goes into TX and after the sentdone is signalled it goes back to Listen, but if you don't send something it stays in Listen-mode, unless you call splitcontrol.stop(). Make sure you only try to send when the radio is on, so when a startDone has been signalled. regards Ruben Date: Fri, 20 Mar 2009 14:03:57 -0700 From: [email protected] To: [email protected] CC: [email protected] Subject: [Tinyos-help] Need your Help: Battery Voltage measurement 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.
