[Tinyos-help] reduce radio's power consumption

2013-02-04 Thread Farzad Samie
Hello I'm trying to measure the radio module power (in send/receive state). My platform is telosb (tinyos2.x and radio module is cc2420). I use low power listening interface. I have two nodes: The first one is just a sender; it should only send packet and doesn't need to receive any thing. I've

this short period before sending packet is the time interval when the radio listens to career to find out whether it is free or not. IOW, it's for avoiding conflict. Right? How can I reduce its length? Farzad On 04.02.2013 17:37, Christian Haas wrote: > On 02/04/2013 04:15 PM, Farz

Hi, I'm using tinyos-2.1.0 and telosb (with cc2420 radio). I wand to just send one packet periodically (don't use receiver). I use Low Power Listening to reduce the power consumption as much as possible. I've also disabled CCA check. After measuring the current drawn for sending packet, I saw t
