Since ESP-NOW uses the same underlying Wi-Fi hardware for communication, any Wi-Fi-related activity will block ADC2 operations. Use ADC1 instead of ADC2.

In Development mode, the ESP32 encrypts the flash contents on the fly when writing. In Release mode, you must provide pre-encrypted binaries.

You can set CONFIG_BOOTLOADER_LOG_LEVEL_NONE to minimize logging overhead.

You can switch to a programmable digital servo.

Check if the CONFIG_SECURE_BOOT_KEY_DIGEST or CONFIG_SECURE_BOOT_ALLOW_KEY_ROTATION options are enabled in your bootloader.

An external pull-up resistor can strengthen the high-level state of GPIO0 during resets and reduce susceptibility to noise. Use a resistor value in the range of 4.7 kΩ to 10 kΩ. Lower resistance values (e.g., 4.7 kΩ) provide stronger pull-up but increase current consumption slightly. Connect one sid...

The power supply must provide a stable voltage (typically 3.3V for ESP32-S3) without significant dips or noise during boot. Check if the power supply can handle peak current requirements (ESP32 can draw spikes up to 500mA during Wi-Fi operation). Add decoupling capacitors (e.g., 10µF and 0.1µF) near...

You have to esp_sleep.h and then Access RTC Memory in RISC-V ULP Code.

Your mp3-tf-16p module should be wired correctly to the ESP32. Connect the speaker to the MP3 decoder module. Here is a basic code: #include <WiFi.h> #include <AudioFileSourceHTTPStream.h> #include <AudioGeneratorMP3.h> #include <AudioOutputI2S.h> const char* ssid = "YOUR_WIFI_SSID"; const char* pas...

If you continue facing challenges, consider using Visual Studio Code with the ESP-IDF extension.
