Re: Connecting ESP32 to internet in LowPower setup.

Does it matter how power hungry WiFi is if it's only going to be awake for 5 seconds once every 24 hours?

Re: How to use ESPAsyncWebServer in ESP32??

And I can't read minds. How about you post the rest of the message from the compiler then? It will say something like "...included in file abc.h"

Did you install it using the library manager? I'd be surprised if that version had an issue like this.

Re: On-Board LED on the Wrover-B ?

They look the same to me.

You can read about the board you have here:
https://docs.espressif.com/projects/esp ... vkitc.html

It doesn't appear to have an LED other than the power indicator.

Re: A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

The Boot button is 0. I'd suggest opening your serial monitor. Then hold down Boot, don't be shy, you can't do it too early and there's no harm in holding it longer than necessary. Give the reset button a good click and you should see some output saying that it's in download mode. Make sure that wor...

Re: ESP32 deep sleep current consumption

Tell us all about your setup, it could be a number of things. What module and/or board, what else is connected to it, your code, etc.

Re: Variable doesn't update between cores

Arduino delay () is not the same as vTaskDelay() - which you should use. delay() does not a taskswitching, vTaskDelay does. FYI vTaskDelay is exactly the way ESP32 implements delay in Arduino. https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-misc.c#L124 void delay(uint32...

Re: A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

That's Vin and GND for the AMS1117. 4.35V seems a little low - you would expect USB to be around 5V +-0.25 - but there might be a diode or something in between to explain that drop. Regardless, it should enough for the voltage regulator to produce a ~3.3V output (probe Vout and GND with the multimet...

Re: Avoid public Hotspot captive pages

It's not a standard protocol. The short answer is no, not possible.

Re: ESP32 2Tasks on 2 Cores - Board reset

It looks like you're checking if 'taskYieldRequired' but not actually yielding.

Code: Select all

if(taskYieldRequired == pdTRUE)
{
  taskYIELD();
}
