I decided to try out ESP-IDF and my device works fine there. So something to do with the Arduino IDE/Code?

I have gone back to the blink sketch and I see that it works.
But the ascii table example which writes to the serial port does not work. No output.
But it programs the device on the same serial port so it must be working?

This is all very odd.

I have even tried the same on another device (same ...

I have a bare bones DFROBOT FIRE BEETLE ESP32-C6 that seems to go into a boot loop

How can esp_wifi be installed/linked in Arduino IDE? I found no hint how to do that.


I would do this

Go to File - Preferences
In the settings tab at the bottom there should be a title called "Additional board manager Urls" enter the following

I believe you need to have the 3.0.0.alpha3 or later library. By default I think when you ...

I found that if I put a delay after digitalWrite(LED_BUILTIN, HIGH); like delay(1000) it is working. But the esp32-c6 has some sort of broken/limited usb support. When it goes to light sleep the usb chip is disabled but it does not get reenabled after coming out of light sleep. Hence usb serial ...

I bought a DFROBOT FireBeetle ESP32-c6 device and I did some testing with light power saving. So far it just hangs the device.

My code is quite simple

[Codebox]
#include <esp_wifi.h>
#include "driver/uart.h"

#define TIMER_WAKEUP_TIME_US (2 * 1000 * 1000)


void GoToLightSleep() {
if ...
