I have received a notification email from Espressif indicating a new release 2.1.1. In Github appears as the latest version https://github.com/espressif/esp-idf/releases , I have updated following the instructions on the page the esp-idf and I have updated the toolchain, but when compiling an app th...

Sorry for the delay in answering, I've been running a lot of tests. Yes, when I connect the button to pin 3.3v and D4, it works correctly. That is to say, when I press the button, 3.3v hits the pin. The problem was in the code, adapting the example of esp-idf/gpio didn't work for me. However, by con...

Thank you very much for your reply. I'm testing two identical boards, like the link board, the first one powered by a MB102 protoboard source and the second one with a micro usb cable and 2A wall adapter. Now I have problems with the button, the pir and touch pads work. I have activated the internal...

Hi guys, as I mentioned in another post I'm doing a small project with exactly this plate and https://es.aliexpress.com/item/ESP-32S-Development-Board-Esp32-Module-2-4-GHz-dual-mode-Wi-Fi-and-Bluetooth-chips/32803195774.html?spm=a2g0s.9042311.0.0.DW8aye . The project is basically responsible for rec...

Maybe this is the key...in the Kolban's book: When the ESP32 starts to transmit over wireless, that can draw a lot of current which can cause ripples in your power supply. You may also have other sensors or devices connected to your supply as well. These fluctuations in the voltage can cause problem...

When I start the monitor, this message appears in yellow: W (67) rtc_clk: Possibly invalid CONFIG_ESP32_XTAL_FREQ setting (40MHz). Detected 40 MHz.

Hello, everybody, I have a problem with my board (is this https://es.aliexpress.com/item/ESP-32S-Development-Board-Esp32-Module-2-4-GHz-dual-mode-Wi-Fi-and-Bluetooth-chips/32803195774.html?spm=a2g0s.9042311.0.0.54qhHF ), I'm doing a small project, which registers a timer, a button (Pin D4) and 7 tou...

Hello ESP_Sprite, thank you for your reply. Yesterday, after searching for a lot of information and doing a lot of tests with the examples, I updated the IDE and toolchain, and now everything works perfectly. I believe that these boards I have bought do not have a 5v output to supply peripherals at ...

Hello everyone, I have bought a couple of boards https://es.aliexpress.com/item/ESP-32S-Development-Board-Esp32-Module-2-4-GHz-dual-mode-Wi-Fi-and-Bluetooth-chips/32803195774.html?spm=a2g0s.9042311.0.0.pitsuQ in aliexpress, and I find that some functions of the examples don't work, like boot_counter...
