6 years ago If you are not going to set all values you should wifi_config_t wifi_config = { 0 };
What happens if you reboot does (1582) nvs: nvs_get ap.max.conn 1 change to 4

6 years ago as @negativekelvin says, the error message:
I (172692) wifi: max stations already connected to ap!
e8:2a:44:6f:60:01, AID = 0
is telling the truth.
You have Wifi AP configured for only 1 connection. and your cellphone is first in line.

6 years ago No it is definitely weird because "max stations" comes at 34s but SYSTEM_EVENT_AP_STACONNECTED does not come until 47s. Then even after SYSTEM_EVENT_AP_STADISCONNECTED there is no free slot. You should check esp_wifi_ap_get_sta_list().

Whoops, I did not post the whole code.
wifi_config_t wifi_config;
wifi_config.ap.authmode = WIFI_AUTH_WPA_WPA2_PSK;
wifi_config.ap.beacon_interval = 100;
wifi_config.ap.channel = 7;
wifi_config.ap.max_connection = 4;
std::strcpy((char *) wifi_config.ap.password, CONFIG_FLYHERO_WIFI_WPA2_PASSPHRASE);
std::strcpy((char *) wifi_config.ap.ssid, CONFIG_FLYHERO_WIFI_SSID);
wifi_config.ap.ssid_hidden = !CONFIG_FLYHERO_WIFI_SSID_VISIBLE;
wifi_config.ap.ssid_len = 0;You should check esp_wifi_ap_get_sta_list()
I have modified the app to print num of stations every 500 ms. WIth the same app I managed to connect with my phone and tablet without a problem (num of stations 2).

This appeared in my dmesg log after unsuccessfull connection to ESP:
[ 805.521802] wlp3s0: authenticate with 30:ae:a4:0a:c2:4d
[ 805.551588] wlp3s0: send auth to 30:ae:a4:0a:c2:4d (try 1/3)
[ 805.553497] wlp3s0: authenticated
[ 807.004842] wlp3s0: aborting authentication with 30:ae:a4:0a:c2:4d by local choice (Reason: 3=DEAUTH_LEAVING)I would say that I have problems with my Qualcomm Atheros QCA9377 driver but I don't quite understand why ESP claims that max stations are already connected.

On ESP? I have set it to verbose.

6 years ago Oh ok sorry. That is weird that num of stations 1 without any events. Something your WiFi driver on Debian is doing that confuses esp32, not sure which has the bug.

6 years ago Reinstalling Network Manager on my system made this issue appear less often. I strongly believe that the problem is on my system rather than on ESP.
Environment
git rev-parse --short HEADto get the commit id.): 22da5f6deProblem Description
I am unable to connect to ESP AP with my laptop with error message
wifi: max stations already connected to ap! <station>e8:2a:44:6f:60:01, AID = 0(e8:2a:44:6f:60:01 is MAC of my laptop) while Android phone connects without a problem (f4:f5:db:c4:c8:7d MAC of Android phone).First I have been using
Then I changed
wifi_config.ap.max_connectionto 4 but the problem still persisted => resetting the chip did not help. After runningmake erase_flashand reflashing the app the problem disappeared.Debug Logs
