[Bug]: Heltec tracker (or ESP32-S3 in general?) user button doesn't work while in light sleep

Heltec Wireless Tracker

Firmware Version

2.5.? (a private build from today's master)

Description

While working on #4154 I noticed that the heltec tracker board is not automatically waking from light sleep when the user presses a button.

For instance (if board is configured as a router so that it sleeps and turns the screen off often), the last log messages seen before light sleep are:

DEBUG | ??:??:?? 7 [Screen] haveGlyphs=1
DEBUG | ??:??:?? 8 [Screen] haveGlyphs=1
INFO  | ??:??:?? 8 [PowerFSM] Turning off screen
INFO  | ??:??:?? 9 [PowerFSM] lsEnter begin, ls_secs=86400
INFO  | ??:??:?? 10 [PowerFSM] setup LORA_DIO1 (GPIO14) with wakeup by external source

The radio is able to wake the board (good), but also the user button on the board should also be sufficient for wake. The wake does not occur if you press the button. I suspect that something is wrong on the esp32-s3 gpio config for that button. It should be configured to generate an interrupt to wake the CPU from sleep (so we can then run our regular button processing)

Alas, I don't think I'll have time to investigate this problem before I leave town. So recording it so that it is known and perhaps someone else can dig into it as needed.

Relevant log output

No response

Just as an initial report: I checked Heltec Wireless Paper with 2.5.0.d6dac17 from the web flasher, and the user button is waking from light-sleep as expected, so this might be version specific or device specific. I'll try building master later on and see if anything changes.

Update: not seeing any issues with current master (2.5.0.5bc17a9)

I am seeing this on my nodes with cardkbs while in lite sleep. User button no longer allows the node to wake, only wakes when I press the keyboard

@HarukiToreda With Heltec V3, right?

Seems like they're coming out of Deep Sleep just fine with the user button interrupt. Been using this on my V3 and Tracker. I wonder if we just need to A/B compare those.

(btw: it is taking a bit longer to setup our new rental apartment than expected, so I won't be back to recreational github meshtastic futzing until about 10/17 :-( )
