Setting wifi configuration

Hi all,
I want to connect to two wifi networks with the difference of some interval of time.
for example: network1 for 10 min and network2 for 10 minutes.
but for changing the configuration I want to stop the wifi then set the configuration and then start the wifi.
that is in idf like->>>
Code: Select all
ESP_ERROR_CHECK( esp_wifi_set_config(WIFI_IF_STA, &wifi_config1) );
ESP_ERROR_CHECK( esp_wifi_start() );
esp_wifi_stop();
ESP_ERROR_CHECK( esp_wifi_set_config(WIFI_IF_STA, &wifi_config2) );
ESP_ERROR_CHECK( esp_wifi_start() );
esp_wifi_stop();
ESP_ERROR_CHECK( esp_wifi_set_config(WIFI_IF_STA, &wifi_config1) );
ESP_ERROR_CHECK( esp_wifi_start() );
So does it affect the performance of esp32?
Or there is any another solutions to work this way?

How about just disconnect wifi, set up new config and reconnect to wifi again?

yes. It will also work.
but I want to ask you that it will affect the performance of esp32 or not.
because I want to do it for several times for whole life cycle of esp32.

I think it just like using wifi on mobile phone. When use want to connect to another wifi, you just disconnect and reconnect. And calling
is the same with disable and enable wifi on mobile phone and doing this periodically is not good.
So in my opinion, if you just want change wifi ssid, just disconnect, set up new wifi ssid and reconnect is good choice.

Ok. thank you for your response.

Since by default Wi-Fi configuration is stored into flash, you may want to call
esp_wifi_set_storage function with WIFI_STORAGE_RAM argument. In this case configuration will not be saved in flash, and flash lifetime will not be affected.

Hi,
We are storing WiFi configurations into flash memory as per our requirements. So, what will be the lifetime of flash operation for single device? Because we are also in same phase like many times WiFi configurations will be changed as per our project requirements.
