Re: RTOS SDK 2.1 : Switch OFF the wifi without enter in sleep mode

Maybe you can try force modem sleep, modem sleep is only switch off the RF afaik.

Code:

void fpm_wakup_cb_func1(void)   { 
   wifi_fpm_close();
   wifi_set_opmode(STATION_MODE);
   wifi_station_connect();
 }
void user_func() 
{ 
wifi_station_disconnect();  
wifi_set_opmode(NULL_MODE); 
wifi_fpm_set_sleep_type(MODEM_SLEEP_T); 
wifi_fpm_open();

// wakeup automatically when timeout. 
wifi_fpm_set_wakeup_cb(fpm_wakup_cb_func1); // Set wakeup callback  
wifi_fpm_do_sleep(50*1000);   #endif  
}

I post my self reply for other user (I found this information on espressif document 20a-esp8266_rtos_sdk_programming_guide_en.pdf page 28 :
to switch OFF the RF part

Code:

    
wifi_station_disconnect();
wifi_set_opmode(NULL_MODE);
wifi_set_sleep_type(MODEM_SLEEP_T);
wifi_fpm_open();
wifi_fpm_do_sleep(5*60*1000); //sleep for 1min

To switch ON the RF PART

Code:

wifi_set_opmode(STATIONAP_MODE);
wifi_station_connect();       // connect to AP

Please comment this post if you see any limitation or miss understanding from myself

RTOS SDK 2.1 : Switch OFF the wifi without enter in sleep mode

2019-06-11T17:14:34+08:00

Hello,
I would like to switch OFF WiFi but still active the main MCU for survey process on some input and send alert by WiFi, is there any way to switch OFF the WiFi alone without entered in deepsleep mode

Thanks
Thierry,
