Afternoon folks,

I was wondering if there was any way to trigger a low power mode with delayed wakeup using the modified Arduino IDE to program the ESP8266?

I've done a bit of reading and don't mind adding a wire to the board to connect the reset pin to a GPIO.

Any suggestions?

Thanks, Phil

Add to the top of your sketch...

Code: Select all

extern "C" {
  #include "user_interface.h"
}

Then when you want to sleep...

Code: Select all

system_deep_sleep_set_option(0);
system_deep_sleep(60000000);

(The time is in microseconds)

You need to connect the RESET and GPIO 16 pins together for this to work... They are not exposed in all of the ESP boards.
