How can I turn off the radio on ESP32?

Hi,
I need, in order to save battery, turn off the radio and the BLE. How can I do that on Arduino IDE?

I turn off BLE with btStop()

Thank you very much!
But that works on Arduino IDE??
I included <WiFi.h>. How must I call that function?

[CelliesProjects]

For wifi you can use:

WiFi.mode( WIFI_MODE_NULL );

should work in Arduino IDE.

Thank you!

With "WiFi.mode( WIFI_MODE_NULL);" The current compsuntion is the same.
I teste with and without that line and I dont see current variation.
Is there another way to turn off the radio part on the ESP32??

I am not sure, the above info came from issue #75.

Maybe turn of both radios?
They may be implemented as a single radio that is multiplexed.

There is an example for this: https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/examples/WiFiBlueToothSwitch/WiFiBlueToothSwitch.ino

to turn wifi and Bluetooth off:

WiFi.mode(WIFI_OFF);
btStop();

Thank you very much, friends!

Stopping bluetooth with btStop(); will save energy?

btStop doesn't work. It freezes the app.
esp_bt_controller_disable doesn't return anything. Just blocks the app
