Wake stubs are executed very early during the wake-up process, and their execution time is limited. The "watchdog timer" reset (TG0WDT_SYS_RST) is likely triggered because your code in the wake_stub function takes too long. You can edit your code like this: #include <stdio.h> #include "esp_sleep.h"...

I'm working on a project using an ESP32-S3, where I want to achieve the following: - Wake up the ESP32 from deep sleep using a button press on a GPIO pin (using EXT0 wake-up). - Check the state of the same GPIO in the wake stub function to determine if the button is being held for 4 seconds. here is...

Issue, I think, is that it works *in this case*. When you enter light sleep manually, the WiFi base station has no idea you're doing so, and it might disconnect you if it runs into a timeout and needs to send you a packet. If you use automatic light sleep instead, the WiFi stack will coordinate sle...

Hi there, I am working on a low-power project using the ESP32-C3, where the product will be configurable by the user. As part of this project, I plan to utilize both light sleep and deep sleep modes. During my tests, I observed something interesting about the light sleep mode, and I wanted to clarif...

xTaskCreate(scd4x_read_measurements_task, ... , &sensor_data, ... ); sensor_data is local to app_main(), i.e. &sensor_data becomes invalid as soon as app_main() returns. Do not pass a pointer to a local variable to the new task! The new task subsequently writing to this variable will cause stack/me...

Hi i have problems with mbedtls. i am not using mbedTLS APIs directly but i am using certificated MQTT connection. I use AWS IoT Core certificates. i added them manually. Here is output of my code: I (30) boot: ESP-IDF v5.1.4-dirty 2nd stage bootloader I (30) boot: compile time Aug 26 2024 11:28:06 ...

Yeah, issue likely is that the wires you connect to your PSU have a relatively high impedance. WiFi eats up very short spikes of lots of power, and the power supply can't provide that 'fast enough' through the high-impedance lines. As a hack to fix this, I'd suggest soldering a whole bunch of extra...

What are you using as your 3.3V power source? Are you sure it can deliver the >=500mA needed, and that you don't have long lines between it and the board?

My supply is a hy3003-3 power suppy. That can provide 3 ampere current. And i attached my actual PCB design to this post.

I'm using a HY3003-3 power supply, which provides a 3 ampere output.

Hello everyone, I designed a custom ESP32-C3 board using the reference peripheral schematic provided in the datasheet. The only modification I made was the removal of a 0-ohm resistor. The board runs other code without issues, but when I attempt to use Wi-Fi, I encounter a brownout detector error, a...
