[question] wifi radio sleep

[chegewara]

I am wondering if this can be bug or i am doing something wrong. I have turned off power management in menuconfig and wifi is configured with power save NONE:

Code: Select all

    ESP_ERROR_CHECK( esp_wifi_set_ps(WIFI_PS_NONE) );

How this is possible wifi is from time to time in sleep mode:

Code: Select all

I (390332) wifi: bcn_timout,ap_probe_send_start
I (392835) wifi: ap_probe_send over, resett wifi status to disassoc
I (392836) wifi: state: run -> init (100)
I (392836) wifi: pm stop, total sleep time: 0 us / 388279672 us

I (392840) wifi: n:11 0, o:11 0, ap:255 255, sta:11 0, prof:1
I (400219) wifi: n:11 0, o:11 0, ap:255 255, sta:11 0, prof:1
I (400220) wifi: state: init -> auth (b0)
I (401221) wifi: state: auth -> init (200)
I (401222) wifi: n:11 0, o:11 0, ap:255 255, sta:11 0, prof:1
I (403761) wifi: n:11 0, o:11 0, ap:255 255, sta:11 0, prof:1
I (403762) wifi: state: init -> auth (b0)
I (403765) wifi: state: auth -> assoc (0)
I (403772) wifi: state: assoc -> run (10)
I (403913) wifi: connected with AndroidAP, channel 11
I (403913) wifi: pm start, type: 0

It says "total sleep time: 0 us" (out of xxxxx us of connection time), so this part looks correct.
