Cannot get connected devices to softAP

[anihilator]

Hi,

I just only need to get how many devices is connected to ESP8266 in softAP mode. I tried to use wifi_softap_get_station_info() but it tells me no devices connected (devices are connected and confirmed by "station: xx:xx:xx:xx:xx:xx join, AID = 1").

I'm using this code:

Code: Select all

      int count = 0;

      struct station_info * station = wifi_softap_get_station_info();
      while(station)
      {
         os_printf("bssid : "MACSTR", ip : "IPSTR"\n", MAC2STR(station->bssid), IP2STR(&station->ip));
         count++;
         station = STAILQ_NEXT(station, next);
      }

      wifi_softap_free_station_info();
      os_printf("count %d\r\n", count);


Thx for possible help.

I'm sad that after 3 weeks nobody tried this. Now I upgraded to latest SDK esp_iot_sdk_v1.0.1_b2_15_04_10 and again no success. Can someone explain it to me?

Hi，

So sorry that we missed your message.

I tried your test code, and it's fine, it can get the station infor ..

Here is my test log

Code: Select all

station: c8:3a:35:cc:14:94 join, AID = 1
bssid : c8:3a:35:cc:14:94, ip : 192.168.4.2
count 1


Test code is

Code: Select all


void check_station_info(void *arg)
{

int count = 0;

      struct station_info * station = wifi_softap_get_station_info();
      while(station)
      {
         os_printf("bssid : "MACSTR", ip : "IPSTR"\n", MAC2STR(station->bssid), IP2STR(&station->ip));
         count++;
         station = STAILQ_NEXT(station, next);
      }

      wifi_softap_free_station_info();
      os_printf("count %d\r\n", count);

}

void user_init(void)
{
    os_printf("Hello from ESP8266\n");
   
    wifi_set_opmode(STATIONAP_MODE);

    os_timer_disarm(&client_timer);
    os_timer_setfn(&client_timer, (os_timer_func_t *)check_station_info, 0);
    os_timer_arm(&client_timer, 5000, 1);
}

Hi, thx for reply.

I tried your code and no result. But Im not using DHCP but static IP addresses on both sides. Can it make sense?

Hi,

wifi_softap_get_station_info can only be used when DHCP on ,right now.

Thanks for your reporting , we will think over your request.

Hi

Thanks for replying (AFTER 1 MONTH). I sent bug report to this problem and I WANT that you will pay me money for bug reporting. Information about that this function only works in DHCP is nowhere written and I spent too much time with this problem and you answer me THIS?

Any news about reported bug?
