Use of esp_sleep_enable_wifi_wakeup in ESP32

[StegoDE]

Hi together,

I'm currently developing an SmartWatch using the TTGO Watch V2 2020 from LilyGo and I'm trying to maintain WIFI connection during light sleep. The light sleep is working fine and i stumpled accross the function "esp_sleep_enable_wifi_wakeup" in "the esp_sleep.h". Unfortunally there is no description of it and when I try the function out, I get as response "106 not supported". Has anyone of you successfully used this function?

Kind Regards

That function is not available on ESP32, only the later variants.
