For your case, I think you can call "system_deep_sleep_set_option(1)" and reboot to go to normal mode. You can use RTC memory to store the status / operation-mode.

I have read some topics they all said it is no API here.In a topic a friend use system_deep_sleep_instant() replace of system_deep_sleep() also made the time system work shortten 96ms before fall into sleep.But I can't make the project with error undefined function.
In my project,I need a very low cost of the power,so I make the module deepsleep 10s everytime when it finish work -- AP scan as a station -- and don't turn on the wifi circurit when wake up.
If anyone give a solution ,it will be very thanks full!
