We have 10 Electron running firmware v0.7.0. Half off them will not wake up at all after calling: System.sleep(SLEEP_MODE_SOFTPOWEROFF, SLEEP_TIME). Using: SYSTEM_MODE(SEMI_AUTOMATIC); SYSTEM_THREAD(ENABLED); I find it hard to reproduce the error as it affects only half off our fleet. I know t…

Is SLEEP_TIME a constant? If not, double check that it never gets negative. Make sure the WKP pin is not HIGH when going to sleep.

What to do if the design has WKP pulled high and the device is put in sleep mode? Is there a work around (such as setting as an output and driving low?)

This is an open issue [image] Issue: If WKP pin is held HIGH on deep sleep wake, RTC alarm and future LOW to HIGH transition on WKP will not wake device. opened by technobly on 2017-02-28 If WKP pin is held HIGH on deep sleep wake, RTC alarm and future LOW to HIGH transiti…

Thank you - well noted for future designs.

Thank you for the response. Is there any workarounds for this problem? I’m using an modified version of the Asset Tracker, where I need to wake on movement. Does any example code for how to make sure the LIS3DH is not keeping the WKP High before going to sleep exist?

Found a couple of answers here if anyone is interested. asset-tracker-accelerometer-gps-problem

The fix is basicly to check for movement and if there is movement don’t use SLEEP_MODE_DEEP and SLEEP_NETWORK_STANDBY.
