Rispondi a: ESP32 WOR in Deep Sleep

[Renzo Mischianti]

Ciao Alexzupo,
Penso che prima di tutto devi fare una wake simile a questa this example

in particolare questa parte

 esp_sleep_wakeup_cause_t wakeup_reason;
 
    wakeup_reason = esp_sleep_get_wakeup_cause();
 
    if (ESP_SLEEP_WAKEUP_EXT0 == wakeup_reason) {
        Serial.println("Waked up from external GPIO!");
 
        gpio_hold_dis(GPIO_NUM_21);
        gpio_hold_dis(GPIO_NUM_19);
 
        gpio_deep_sleep_hold_dis();
 
        e32ttl.setMode(MODE_0_NORMAL);
 
        delay(1000);
 
        e32ttl.sendFixedMessage(0, DESTINATION_ADDL, 23, "We have waked up from message, but we can't read It!");
    }else{
        e32ttl.setMode(MODE_2_POWER_SAVING);
 
        delay(1000);
        Serial.println();
        Serial.println("Start sleep!");
        delay(100);
 
        if (ESP_OK == gpio_hold_en(GPIO_NUM_21)){
            Serial.println("HOLD 21");
        }else{
            Serial.println("NO HOLD 21");
        }
        if (ESP_OK == gpio_hold_en(GPIO_NUM_19)){
                Serial.println("HOLD 19");
            }else{
                Serial.println("NO HOLD 19");
            }
 
        esp_sleep_enable_ext0_wakeup(GPIO_NUM_15,LOW);
 
        gpio_deep_sleep_hold_en();
        //Go to sleep now
        Serial.println("Going to sleep now");
        esp_deep_sleep_start();
 
        delay(1);
    }
//  e32ttl.setMode(MODE_0_NORMAL);
//  delay(1000);
    Serial.println();
    Serial.println("Wake and start listening!");

rimuovi anche e32ttl.begin(); ed inseriscilo solo sull’else

e prova a leggere il buffer nell’if

    if (ESP_SLEEP_WAKEUP_EXT0 == wakeup_reason) {
        Serial.println("Waked up from external GPIO!");
 
        gpio_hold_dis(GPIO_NUM_21);
        gpio_hold_dis(GPIO_NUM_19);
 
        gpio_deep_sleep_hold_dis();
 
        e32ttl.setMode(MODE_0_NORMAL);
 
        delay(1000);
 
        e32ttl.sendFixedMessage(0, DESTINATION_ADDL, 23, "We have waked up from message, but we can't read It!");
    }

senza I vari hold_dis, leggi il buffer dell’UART direttamente
se trovo del tempo lo testo anche io in maniera autonoma.
