Hardware

Heltec Wireless Paper All ESP32(?)

Firmware Version

2.3.4.fd704728

Description

Unable to enter light-sleep.

Added some additional debug output, which seems to show that device is kept awake by timed state transition at PowerFSM.cpp L351-L353

As a test, disabling these lines did allow the device to enter stateLS as expected.

Not sure what the intended purpose of the transition is; catch-all for any missed state changes maybe?
Didn't notice any immediate consequences of disabling the dark-to-dark transition. Will do some more testing later so try and identify where, if anywhere, it has an effect.

Light sleep duration was set at 35 seconds during the testing.
