light sleep problem

[guangzong]

Hi,
I am trying to make esp32 enter light sleep mode.
After I set up light sleep, I saw 45 mA current consumption. But in the datasheet, it should be 0.8mA.

Following is the code.

esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP *uS_TO_S_FACTOR);
esp_light_sleep_start();

My suspect ion is WiFi or Bluetooth still working.
Can you tell me how to turn it off and why power consumption is 45mA;

Best,
Guangzong

What hardware are you using to measure this? (Devboard, loose module, own board, ...)

[guangzong]

I read the current from the power supply directly.

That's nice, but I'd like to know what hardware you are testing this on. Devboards may have loads of other components leading to high power use.

[guangzong]

I upload the schematic. No SD and no camera attached. It doesn't have too much load.

That looks OK; the AMS1117 has a pretty high quiescent current but not 45mA worth of current. Can you post your code? Also, are you following what the ESP-IDF documentation says to do, specifically "Before entering deep sleep or light sleep modes, applications must disable WiFi and BT using appropriate calls (esp_bluedroid_disable(), esp_bt_controller_disable(), esp_wifi_stop())." ?

Thank you.
The problem solved.
