Hello, I've given up with deep sleep, because it works for some times then it hangs on reset (gpio 0 and 2 up, 15 down, 16 to RST), as it is reported in many other forums.

I've made modem sleep work, it activates and deactivates, but it passes from 76mA to 22mA only:

WiFi.disconnect();
WiFi.mode(WIFI_OFF);
delay(1);
WiFi.forceSleepBegin();
delay(15000);

when in delay stays at 22mA and then loops.

I've managed to enter light sleep, and it goes from 76mA to 7mA, but I'm unable to wake it up:

wifi_fpm_set_sleep_type(LIGHT_SLEEP_T);
wifi_fpm_open(); // Enables force sleep
Serial.println("A");
wifi_fpm_do_sleep(0xFFFFFFF); // Sleep for longest possible time
delay(1);
Serial.println("A");

it never gets to "A", and it stays at 7mA

Doing any combination of wait with both the wifi_fpm_do_sleep argument or with the delay:

wifi_fpm_do_sleep(10000000); // Sleep for longest possible time
delay(10000);
Serial.println("A");

it gets to print "A", but never goes to 7mA, always 76mA.

Any suggestion?
At this point going to 7mA and back would be great.

Thanks!

Slowly losing faith with the ESP, I have implemented two devices with light sleep and brand new batteries were both dead within hours.

no problems with deep sleep on ESP-01 here ...

for light sleep, maybe this will be informative:
