If the board still doesn’t show up after installing the FTDI or CP210x drivers, it’s worth checking how the esp32 is powered and initialized. Some boards, especially older dev kits or custom modules, don’t auto-reset when flashing — meaning you might need to manually hold BOOT while tapping EN to ...

I’m using the ESP32-WROOM
Module Development Board for a small IoT camera project, but the Wi-Fi stream occasionally drops when Bluetooth is active. Has anyone found an effective way to maintain stable dual-mode (Wi-Fi + Bluetooth) performance—maybe through task prioritization in FreeRTOS or by ...

It’s tricky because Espressif never really gives a clean spec sheet on the hardware WDT, but here’s what’s been pieced together from SDK code and a lot of trial/error:

The hardware watchdog lives in the RTC side of the chip and keeps an eye on the system task queue (Wi-Fi + RTOS scheduler).

It’s ...

I’m building a digital thermometer using the MAX30205 body temperature sensor with Arduino Uno. The wiring is:

VCC → 3.3V

GND → GND

SDA → A4

SCL → A5

I used the example code from the library, but the readings seem stuck around 32–33 °C, even when I touch the sensor. I expected it to rise closer ...
