Hi Mark,
We are trying to get the power consumption too. We are using a digital
oscilloscope and when the radio is on (calling "GenericComm.start") and a
package is trasnmitted, a fluctuation occurs during a short time (first
positive and then negative). We think (but not sure) that it can be due to
transitotry behaviors during the process to start the radio.
Somebody has tried to get with an oscilloscope the power consumed during the
transmission of a package?
Best Regards,
Diego

Subject: [Tinyos-help] Power Consumption in Tmote
Hi All,
I was just wondering if the tmote moves from sleep mode to calling
GenericComm.start() quite a bit of extra power is consumed (about a 20mA
jump) and remains being consumed until it is stopped again even if nothing
else is happening. I was just wondering what is the major cause of this
power consumption?
Also it would appear that when a transmission is taking place, whatever
was consuming this power is interrupted and a different *lower* power
flucuation occurs. Can anyone explain why the power consumption is lower
when transmitting than when not? Thanks.
Regards,
Mark
