Deeplseep issues / fix

[jvgelder]

I was having issues getting deep sleep to work using the battery (no usb power) and the regular esp functions esp_deep_sleep_start and esp_sleep_enable_timer_wakeup().
When I realized it had a bat boost converter I managed it to get it to work by:

pinMode(POWER_HOLD_PIN,OUTPUT);
digitalWrite(POWER_HOLD_PIN,HIGH);
gpio_hold(GPIO_NUM_12); // tell the esp to keep pin high even in sleep

I am not sure where this information belongs but i thought it might be useful for anyone else bonking his head against the wall.

this worked for me (Finally)

pinMode(POWER_HOLD_PIN,OUTPUT);
digitalWrite(POWER_HOLD_PIN,HIGH);
gpio_hold_en(GPIO_NUM_12); // tell the esp to keep pin high even in sleep
esp_deep_sleep_start();

is it time to close this issue @jvgelder? It's been open for years.

better late than never i guess but was this the fix? m5stack/M5Unified@5986a80
I haven't tested it my self but if deepsleep now automatically holds the power pin yes, but i don't see any references to documentation updates ?

The ESP-IDF equivalent of this would be

gpio_set_direction(POWER_HOLD_PIN, GPIO_MODE_OUTPUT); // Set output mode
gpio_set_level(POWER_HOLD_PIN, 1); // Set HIGH
gpio_hold_en(POWER_HOLD_PIN); // Hold value
gpio_deep_sleep_hold_en(); // Even in deep  #sleep

I found this to work for me in ESPHome
