i have a simple wifi station mode and lwip socket like this


esp32 (client) ----------------AP-------------- Ipad(server)


connect AP and some time later with logs like this
I (30947) wifi: bcn_timout,ap_probe_send_start
I (33447) wifi: ap_probe_send over, resett wifi status to disassoc
I (33447) wifi: state: run -> init (1)
I (33447) wifi: pm stop, total sleep time: 0/12992468
I (33447) wifi: n:5 0, o:5 2, ap:255 255, sta:5 2, prof:1

and socket disconnected, wifi disconnected and reconnect


why is this happening??

Disabling interrupts for a long time (seconds), having tasks which run at high priority, suspending the scheduler — all these can cause similar errors.

I have this problem just after Interrupt wake up of Light Sleep. Any solution?
My system is very unstable :'(

I found that the ENOMEM is the error returned by esp_wifi_internal_tx_by_ref ( ESP_ERR_NO_MEM ). packet sniffing, using monitor mode of ESP32 wifi stack and using ESP32 BT/BLE stack. I (11552633) wifi: bcn_timout,​ap_probe_send_start.
