Hello @Saichander

have a look here: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/gpio.html . GPIO34 to GPIO39 don't have internal pull-up (or pull-down) capabilities.

Excerpt from that page: GPI: GPIO34-39 can only be set as input mode and do not have ...

Hello @andrewandroid

which ESP-IDF version are you using? Running the provided deep sleep example https://github.com/espressif/esp-idf/tree/master/examples/system/deep_sleep on my ESP32C3 works fine and I get the proper wake-up reason. I tried with the latest ESP-IDF from github, e.g. 5.2.x ...

Hello @sircastor

from the ESP32C3 datasheet: https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf

USB - GPIO18 and GPIO19 are USB pins. The pull-up value of a USB pin is controlled by the pin’s pull-up
value together with USB pull-up value. If any of the two pull ...

Hello @ESP_Sprite

I think you meant to write `... same circuit but with IO0 replaced with IO9.`

Hello @kian79

have you tried to ping a different host? have you tried to connect to a different AP?

Thanks
Felix

P.S. the included ping example HostPing.ino works for me.

Hello @lannocm

the way I understand timers to work is like this:
- timer counting up: timer starts at 0 microseconds and when it reaches the alarm value (1000000 microseconds) the interrupt is triggered.
- timer counting down: timer starts at 1000000 microseconds and when it reaches the alarm value ...
