Any smart home device you own that connects to WiFi could be the culprit, and there is likely no way to find out which it is without port scanning it, and recognizing ports, or pinging it and turning things off till the ping stops. Espressif chips are used in tons and tons of smart home devices: sma...

I could not find a working example anywhere, even three years later, so I made one: https://github.com/vonnieda/esp32-examp ... ap-and-sta

Hope it helps!

Thanks,

For what it's worth, and to answer your original question, my company sells a number of ESP32 based products and we have had no longevity issues at all. We have tens of thousands of ESP32 devices in the field, some of them having been running 24/7 for 4+ years.

Which GPIO pins are you using for interrupts? The ESP32 has a bug (?) where GPIO36 and GPIO39 generate spurious interrupts when WiFi or BLE are on. See https://github.com/espressif/esp-idf/issues/4585

Set the output_invert member of the ledc_channel_config_t structure's flags to 1 or 0 respectively.

Thanks for that! Looks like that flag is not in my version of IDF, but easy enough to backport.

Thanks,

Hi all, I have a LED I need to control with LEDC for PWM. The pin is inverted in the hardware, i.e. 1 is off, 0 is on. The LEDC API expects the opposite. I've sort of fixed this by inverting my duty cycle, and that works fine, but when I first enable the LEDC channel there is a very brief flicker wh...

The assumption is probably that most users prefer a more accurate clock over a faster wakeup, especially when using the internal oscillator. You're better off skipping calibration in your case. Thanks for your response, I don't think this applies. I'm not using the internal oscillator. I'm referrin...

Hi all, I'm working on decreasing my deep sleep wakeup time. Currently the longest part of the process seems to be calibrating the 32kHz external crystal I'm using for RTC. With the recommended calibration cycles of 3000 it takes about 200ms. I believe I understand all the menuconfig options for thi...

Hi all, Does anyone have any experience with ESP32-PICO-MINI-02 availability yet? I'm considering this module for a design but there seems to be very few available in from the normal distributors. DigiKey and Mouser are both showing 8 week lead times, and I'm wondering if that is legit during this c...
