ESP32-C3 won't light sleep for specified DTIM

[fgervais]

I did some test with light sleep.

My router beacon interval is set at the default 100ms.

If I set the router DTIM to 100 then light sleep works as expected, the device sleeps for 10 seconds.

However, if I set the router DTIM to 255, the device will still only sleep for about 10s. The rest of the time it will stay awake.

The 26s DTIM:

The light sleep period:

Is there something I can do to sleep the complete DTIM?

I see, I got caught by the inactive timeout.

Code: Select all

esp_wifi_set_inactive_time(WIFI_IF_STA, 30)

did the trick.
