Hi,
I cannot seem to find the answer.
I've got an ESP32 which needs to be battery power.
I cannot get the power consumption under 0.011 A in sleep mode.
I've tried powering true the USB connector
Even removed the 3.3 regulator from the board, and used an external 3.3 to measure there but got the same result.
I went back to the basic sleep code and still got the same result..
Any idea / tips
#define BUTTON_PIN_BITMASK 0x200000000 // 2^33 in hex
RTC_DATA_ATTR int bootCount = 0;
void print_wakeup_reason(){
esp_sleep_wakeup_cause_t wakeup_reason;
wakeup_reason = esp_sleep_get_wakeup_cause();
switch(wakeup_reason)
{
case ESP_SLEEP_WAKEUP_EXT0 : Serial.println("Wakeup caused by external signal using RTC_IO"); break;
case ESP_SLEEP_WAKEUP_EXT1 : Serial.println("Wakeup caused by external signal using RTC_CNTL"); break;
case ESP_SLEEP_WAKEUP_TIMER : Serial.println("Wakeup caused by timer"); break;
case ESP_SLEEP_WAKEUP_TOUCHPAD : Serial.println("Wakeup caused by touchpad"); break;
case ESP_SLEEP_WAKEUP_ULP : Serial.println("Wakeup caused by ULP program"); break;
default : Serial.printf("Wakeup was not caused by deep sleep: %d\n",wakeup_reason); break;
}
}
void setup(){
Serial.begin(115200);
delay(1000); //Take some time to open up the Serial Monitor
++bootCount;
Serial.println("Boot number: " + String(bootCount));
print_wakeup_reason();
esp_sleep_enable_ext0_wakeup(GPIO_NUM_33,1); //1 = High, 0 = Low
Serial.println("Going to sleep now");
esp_deep_sleep_start();
}
void loop(){
)
