Re: Development using Arduino IDE
You should be able to find what you need about the hardware at: https://github.com/espressif/esp-box/blob/master/docs/hardware_overview/esp32_s3_box_3/hardware_overview_for_box_3.md There is a sensor table that describes the parts being used and for more detail there are links to the schematics on t...

Re: Capacitor has no effect
I assume that you have looked at the battery voltage and it stays above 3.3 + 0.36(HT7833 typical drop out voltage)= 3.66 volts during this time.
The HT7833 has a max drop out voltage of 0.5 volts at 3.3 volt output.

Re: Can I still flash wemos/lolin ESP32 via pin headers if USB is destroyed?
A couple of thoughts. Have you removed the USB to serial chip? The damaged USB to Serial chip could be driving the pins on the ESP. Maybe the pins on the ESP were also damaged and you will not be able to program the ESP.

Re: ESP-32 keeps resetting
Have you tried a different esp32-wroom-32d module?

Re: Preventing a variable from changing in the long run?
I believe that you need to use a int64_t type for your variable. A (signed) long variable will overflow at ~2147 seconds.

Re: how do I change one single bit?
In the past I have used the the bitwise OR, AND or XOR operators (standard C language). You can also create a structure. More details can be found at https://www.codesdope.com/blog/article/ ... -bit-in-c/.

Re: display time since boot
It looks like you assigned the variable microSecondsSinceBoot to an signed 32 bit variable and it rolls over to a negative value at 2^31 microseconds or ~36 minutes. I believe that the esp_timer_get_time() function returns a signed 64 bit value (int64_t) so I would declare the microSecondsSinceBoot ...

Re: Deep sleep not working with ESP BLE MESH
Are there other devices like a LDO regulator or USB to Serial chip on your ESP32 board that could be consuming power?

Re: Arduino IDE Serial Monitor Error Message
I believe you need a Serial.begin(115200); in the setup section. Replace the 115200 with a different rate if you like.
