I have a Wireless Stick Lite V3 (link), programming via VSCode with Platform IO without using the heltec library, rather identifying the device as an ESP32S3 Compatible board. Using the ESP hal I can’t achieve the stated <10uA Consumption.
My code is basicly doing this when going to sleep:
esp_sleep_enable_timer_wakeup(ciclos *1000000);
esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_PERIPH, ESP_PD_OPTION_OFF);
esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_SLOW_MEM, ESP_PD_OPTION_OFF);
esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_FAST_MEM, ESP_PD_OPTION_OFF);
esp_sleep_pd_config(ESP_PD_DOMAIN_XTAL, ESP_PD_OPTION_OFF);
esp_sleep_pd_config(ESP_PD_DOMAIN_VDDSDIO, ESP_PD_OPTION_OFF);
LoRa.sleep();
Serial.flush();
Serial.end();
SPI.end();
Wire.end();
delay(200);
esp_sleep_config_gpio_isolate();
esp_deep_sleep_disable_rom_logging();
delay(200);
esp_light_sleep_start();
In this light sleep mode I get ~5mA while sleeping.
If I change the mode to deep sleep I get 1.22mA while sleeping.
Any guidance on how to achieve the low power consumption using the bare tools would be much appreciated.
It’s very frustrating to see a <10uA board consume 5000uA
