Wireless Stick Lite V3 deep sleep current

Hi,

I have tried to get deep sleep current to go down, but V2 example’s pin sets gives me a boot loop, and other pin sets i found online does not lower current. I now got 1.85mA with USB and 0.87mA with battery.

How do i go lower? I’m especially interested if I can go lower with 5V input (planning to use 4xAA in series in ease of maintenance for others), but if that is not possible, will go with 18650.

Current sleep function:

void deepSleep() {

Serial.println(“Going to Sleep…”);

esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP * uS_TO_S_FACTOR);

Radio.Sleep();

esp_deep_sleep_start();

}
