Deep sleep option 4 - RF works/current consumption is normal after wake up

[jakasi2]

hey,

I connected GPIO16 to RST and wrote a simple program that sends data over WiFi. I am using Arduino IDE so I tried the API calls in the package. I tried:

• Code: Select all

  ESP.deepSleep(10*1000000, RF_DISABLED);

• Code: Select all

  ESP.deepSleep(10*1000000, WAKE_RF_DISABLED);

... and it didn't work. Power consumption drops when the device enters deep sleep mode but goes back to normal when it returns from it. RF also works and I can send data over WiFi.

Then I tried ESP8266 SDK calls. I imported ..

Code: Select all

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

.. and called ..

Code: Select all

system_deep_sleep_set_option(4);
system_deep_sleep(10*1000000);

.. and the behaviour is the same.

How can I wake up the chip with RF turned off (lower power consumption)?

Thanks

hi,
When "deep sleep option == 4", RF disabled after deep-sleep wake up, the device is not able to transmit or receive data after wake up.
Could you give me a test demo using 8266 SDK ?
