ECO mode cause board to constantly reboot when sleep time set above 2100 seconds

[Marvin-YYC]

the bug

I was testing a board outdoors running on a battery and solar panel, using ECO mode set at 1800 seconds (30 min) After several days I switched the board to go into ECO mode for 3600 seconds (60 min). The battery started to drain very quickly, and I discovered that the board was stuck in a reboot loop. When I changed the sleep time to 2100 seconds the issue went away. I tested at 2200, 2500, 3000, 3500 seconds and the reboot loop started again.

This is on a TTGO T-Display using CanAirIO Bike with AHT10 Temp + Humi sensor

Sorry, I should have placed this in firmware issues.

Can you post here the log about reboot loop?. I did not test this ECO time with such high values.

Yes, it is a long sample rate for AQI data. With the cold weather, and the short daylight hours here I was trying to extend my battery/solar.

To solve this issue, I made some changues in my own compilation:
In platformio.ini
[env:TTGO_TDISPLAY]
extends = esp32_common
board = esp32dev
lib_deps =
${common.lib_deps}
bodmer/TFT_eSPI @ 2.4.70
lib_ignore =
gui-utils-oled
build_flags =
${common.build_flags}
-Os
-DUSER_SETUP_LOADED=1
-DST7789_DRIVER=1
-DENABLE_TFT=1
-DTFT_WIDTH=135
-DTFT_HEIGHT=240
-DCGRAM_OFFSET=1
-DTFT_MOSI=19
-DTFT_SCLK=18
-DTFT_CS=5

-DSMOOTH_FONT=1
-DSPI_FREQUENCY=40000000
-DSPI_READ_FREQUENCY=6000000

In /scr/power.cpp

line 50 esp_sleep_enable_timer_wakeup(seconds * 1000000ull);

And it is working with 2 examples. ! with 2125 seg and other with 3150 seg of deep-sleep.
