Spark Core & Low Power Modes

[wgbartley]

It seems that @peekay123 and myself have kinda thread-jacked another thread with talk about power consumption. I vote we move the conversation to this thread.

To continue that thread...

@peekay123

@wgbartley, would it be worth getting my results in there for a bigger dataset? It seems to me that your findings should become a white paper on Core power modes, not just a post. This would be the first proper profiling of power modes and an opportunity to present recommended operating modes. One thing that would be cool is to estimate milliWatt/hr or milliAmp/hour figures for battery planning.

Have you seen high peak current consumption like I did? I would love to plot current vs time around the wakeup/publish/sleep event to see how long it takes to wake/connect. I would be more than glad to help if you want to extend the findings and do a more detailed report.

I have not been doing anything super scientific here. Just plugging a Core into the battery and letting it sit on the kitchen countertop until it stops blinking. I don't have any equipment to profile current usage unless I want to sit with my core with a cheap multimeter and hope it picks up current spikes with it's 1-second update cycle. I don't have the spare funds to spring for something fancy like an oscilloscope.
