The above information is not solid. The ESP8266 is a poorly documented system at this point. It will get better. We will update this as more information becomes available. Update November 13, 2015: We now have found out that the use of the os_timer set to a 2ms interrupt will cause ...

Why do we need this TimerInterrupt_Generic libraryFeaturesThis library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, Mega-AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, STM32F/L/H/G/WB/MP1, Teensy, Nano-33-BLE, etc....
// I've measured that the ESP8266 needs around 460 ms to go to light sleep. // So I assume that the delay has to be at least 460ms. esp_delay(time_ms+1, [](){ return wifi_sleeping; }); } // this function is called by the wake up callback interrupt. Do not call it your...
