Re-enable RF after a deepsleep with option 4

[redge76]

Hi,

I can't find anything on how to re-enable wifi after a system_deep_sleep() with the option deep_sleep_set_option(4).
The current workaround seems to call deep_sleep_set_option(0) and then system_deep_sleep(1).
Adafruit seems to be able to re-enable wifi with the arduino environment.
https://github.com/adafruit/adafruit-io ... rigger.ino
I was not able to reproduce this.
People on the arduino github project are also trying without success (WAKE_RF_DISABLED) :
https://github.com/esp8266/Arduino/issues/644
The example code provided by espressif use the set_option(0) solution:
https://github.com/EspressifSystems/low ... ensor_lp.c


So can someone at Espressif confirm how, if possible, to enable wifi after a deepsleep. I was not even able to do it by power reset. Is calling deep_sleep_set_option(0) the only solution ? Is there really anyway to do this without restart ?

Regards,

I have the same doubt. I have not found any information on how to turn on the RF with the ESP8266 running. Can someone help us?

Is there any way to avoid the ESP8266 to sleep in any kind? I am facing this issue. After 30 minutes of inactivity, my ESP12-E goes to sleep without any command and I dont want it. I have to do a ping, inside a crontab, every 15 minutes to avoid it. thanks

Maybe you can try wifi_set_sleep_type(NONE_SLEEP_T); to disable sleep mode.
