Hi,all

I got a crash which seemed to be happened after connected AP for long time. ESP32 disconnected to AP, and print the log like that:
I (19830063) wifi: bcn_timout,ap_probe_send_start
I (19832563) wifi: ap_probe_send over, resett wifi status to disassoc
I (19832563) wifi: state: run -> init (1)
I (19832563) wifi: n:1 0, o:1 1, ap:255 255, sta:1 1, prof:1
I (19832563) wifi: pm stop, total sleep time: 0/-1656040326

It looks like the sleep time was overflowed ?
Anyone can give me some suggestion?
Thanks.

Hello xzwang,
How long did your ESP32 connect to AP? Is it sure to happen or happen by chance?

Hi,ESP_puff

ESP32 has keep connection for several hours. and the crash can reproduce.

The Situation:
1,ESP32 is listening BLE advertising constantly.
2,ESP32 enable WIFI and connect AP.
3,Disable use dual core for FreeTROS in sdkconfig.
4,After several hours, ESP32 received "SYSTEM_EVENT_STA_DISCONNECTED". It may caused by 'I (19830063) wifi: bcn_timout,ap_probe_send_start', just my guess.
5,In my project, ESP32 will do "esp_wifi_connect()" automatically if received "SYSTEM_EVENT_STA_DISCONNECTED".
6,If connect AP again, the crash will not happen. However, if it can't connect AP for sometime, the crash will happen.

This is my ESP32 usage scenario, I hope it can help.
Thanks.
