Is there a deep sleep mode for Fire?

houkensjtu

Hello all,

I'm designing a Fire application which is supposed to be work on battery, and it will be beneficial if I can deep sleep Fire when it's not being used. Is there a way to "Sleep" the unit? Or what's the most common way to reduce power consumption?

Thank you!

Hello @houkensjtu

yes, there is. Two functions are available for that POWER::lightSleep() and POWER::deepSleep()

Also have a look at the sleep example, it uses light sleep and deep sleep functionality.

Cheers

Hi Felix,

Thank you for you quick answer. Looks like you're referring to the Arduino library of M5Stack.
I wonder if there is an equivalent function in UI-FLOW? I'm currently using UI-Flow to program my Fire.
I can also try to burn the Arduino firmware, but I'm worried if I can control the UI as easily as in UI-Flow.

Thx,

Hello @houkensjtu

ok, I see. In UI-FLOW you could use an Execute code block and add something like this for deep sleep:

import machine

#sleep for 10 seconds
machine.deepsleep(10000)

or light sleep:

import machine

#sleep for 10 seconds
machine.lightsleep(10000)

BTW: I found a nice tutorial about MicroPython and sleep modes here.

Cheers
Felix
