I started testing 1.2.1 today and saw an increase in sleep current. I whipped up the following code and tested it on two brand new Borons. One running 1.1.0 and one running 1.2.1. Version 1.2.1: 10 mA Version 1.1.0: 700 uA Test Code: #include "Particle.h" SYSTEM_MODE(MANUAL); void setup() { …

I’m using 1.3.0 and had to use the code below to get into Sleep Stop Mode successfully. The delays were required, just calling system.sleep was not enough to get into sleep mode with 1mA sleep current and .7mA deep sleep current. bool HaveWeTurnedOffModemYet = 0; if (HaveWeTurnedOffModemYet == 0)…

Thank you, RWB. I’ll give it a shot.

Just a heads up that we had a short internal conversation about this topic… @avtolstoy will be leading an effort to make some improvements to Gen 3 sleep modes in the next release.

Are we talking about lower power Sleep Modes?

Hi Will, Were there any updates on this?

Updated sleep modes are coming soon. This will dramatically lower the Boron sleep current; it should be around 140 uA in SLEEP_MODE_DEEP.

That’s great to hear. Any tentative ship date of this new firmware? I’m testing an RTC to toggle the pin to pull it out of deep sleep and am about to cut the trace and jumper to EN to shut it down completely as that brings it from 770 uA to 77 uA. We’ll be doing a bulk build of these boards soon a…

Has the 140uA sleep mode firmware been released yet?

Device OS 1.5.0 should be released today (Monday, February 3, 2020).
