The IP5306 IC, used as a power source for the ESP32-S3 development board, enters standby mode after 32 seconds of no power consumption (e.g., during light or deep sleep). Once this happens, a speaker connected to the ESP32-S3 starts generating a quiet but noticeable sound.
Is there any way to prevent this behavior?
1. Check IP5306 to see if there are registers to adjust the trigger time of standby mode or disable standby mode.
2. Make sure ESP32-S3 is correctly configured for light or deep sleep mode to avoid unnecessary power consumption.
3. Code example: #include <esp_sleep.h>
void setup() {
esp_sleep_enable_ext0_wakeup(GPIO_NUM_0, 0);
esp_light_sleep_start();
}
oid loop() {
// Main loop
}
