<![CDATA[Sleep but leave display on ?]]>To conserve battery power I want to send the M5Stack to sleep for 1 minute, then wake up on timer, check sensors, preform calculations and refresh the display. The back to sleep for 1 minute. I can send the M5Stack into deep sleep but it switches the display off when it goes to sleep. Any ideas how to keep the display showing (does not need to update).

Hi Dr Wino,

That may be problematic....

You may have already read this, and i didn't have time to ready it properly but the info at the link below discusses the ESP32 sleep modes in some detail... Nothing jumped out as a clear solution in a quick skim read.
