is it possible to suspend wifi to save power?

I'm using esp-idf 4.4.2
I want to suspend wifi to save power and recover it when I need, how to do that?
esp_wifi_stop works to stop it, but when I tried esp_wifi_start to recover wifi link, it don't work.

Forgot to mention, BLE is also enabled, I'm using bluedroid, CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE is set to yes.
