Does anybody have an idea why I am not able to achieve a sleeping power consumption under 100 uA? Here is my code, super simple. Note I have tried this on 3 separate Argons with identical results. SYSTEM_MODE(MANUAL); SystemSleepConfiguration config; void setup() { config.mode(SystemSleepMod…

This was determined to be a bug and will be fixed in 3.2

Also, I have tried the current measurements using a Rigol DM3058E and got the same readings.

Thanks for your post - I’m also experiencing higher (~600uA) than claimed current draw in sleep on my Borons (device OS 3.0.0). I have not received any feedback on my forum post which is unfortunate. Out of curiosity, what is your current draw if you pull EN low?

I’ll give that a try in the lab this afternoon and post. Kevin McQuown Principal Engineer Windy City Lab

With EN low I measure 26.9 uA. [IMG_0169]

Interesting. So the excess current is definitely being consumed in the nRF52 and/or ESP32 WiFi module since pulling EN low disables the 3V3 bus to both (see sch here ). I hope one of the Particle engineers would shed shine some light on this since 1.68 mA is a LOT of current in sleep, and is drastic…

I’ll try delaying by 60 seconds before going into sleep today and see what I get.

No change after waiting 1 minute and then entering sleep

Any thoughts/suggestions @rickkas7 or other Particle Engineers? Same goes for my Boron post linked above.

I have submitted a formal support request with ticket 108250.

Thanks, we’re looking into this for you!
