Re: Pull up does not work.
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 softwar...

Re: ESP32-C3 deep sleep GPIO wakeup reason
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. Thanks ...

Re: Interal Pulldown not working on GPIO19?
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-up ...

Hello @ESP_Sprite
I think you meant to write `... same circuit but with IO0 replaced with IO9.`
Thanks

Re: Unable tp ping remote host using ESP32 ping
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.

Re: countdown timer using interrupts
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 ...

Re: PPPoS of ESP-IDF falls back to 2G - cannot connect 4G
Hello @duskotodevski using the pppos_client example my SIM7600G (sorry, I do not have a SIM7000G to test with) does properly connect to 4G with automatic provider selection (e.g. AT+COPS=0) I've added the following line after the line which outputs the operator. It will tell which access technology ...
