Hi Ittipong - No, I don't think it'll work in TOSSIM, especially in 1.x. LPL was new to 2.x.

Many thanks, Ittipong On 17/08/07, David Moss < [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: 1. Compile your application with the preprocessor variable LOW_POWER_LISTENING defined to include the low power listening layer in your radio stack: make telosb lpl (if lpl.extra is in your support/make directory) -or- Makefile: component=xyzC CFLAGS += -DLOW_POWER_LISTENING . There's some other ways of doing that too. 2. In your application, wire into CC2420ActiveMessageC's LowPowerListening interface and call LowPowerListening.setLocalSleepInterval(x); where x is the receive check interval in milliseconds (how often your radio wakes up to see if someone's transmitting). 3. When you're sending a message to a low power listener, you need to tell your own radio about it. Before you send a message, call LowPowerListening.setRxSleepInterval(&myMsg, x); where myMsg is the message_t you're about to send, and x is the receiver's receive check interval. -David _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hassan Naqvi Sent: Friday, August 17, 2007 2:16 AM To: [email protected] Subject: [Tinyos-help] Switching Radio on/off Hi All! I am working on a WSN for indoor environment monitoring. I want to make every senor should send the sensed data when there is a significant change in it. In order to implement this idea I need to make radio switich on and off time to time in order to do power saving. I just started to use TinyOS 2.0 with Tmote Sky motes. Please help me how can I make the Tmote Sky CC2420 on and off time to time. Regards, -Hassan _____ Boardwalk for $500? In 2007? Ha!
