CC3200 AP mode problem

Other Parts Discussed in Thread: CC3200, CC3200SDK

When i use CC3200 as AP mode in our product. We found sometimes station can not connect Ap again. The following is Steps:

1/ Power CC3200 AP device.

2/ Connect CC3200 AP by 1st station(mobile)

3/ Close 1st station WIFI, open another station(2nd station) WIFI and connect CC3200 AP

4/ Close 2nd station WIFI, open another station(3rd station)WiFi and connect CC3200 AP

5/ Close 3rd station WIFI, open another station(4th station)WiFi and connect CC3200 AP

6/ Close 4th station WIFI, open another station(1st station)WiFi and connect CC3200 AP

7/ Then go step 3 again.

After some times, no station can connect CC3200 AP agaion. 

We use the getting_started_with_wlan_ap sample to check and we found same result. We use CC3200SDK_1.0.0 and CC31xx_CC32xx_ServicePack_1.0.0.1.2 and CC3200 LAUNCHXL 4.1.

Why?There is issue in server package?

Best Regards!

    Hi James,


    We try to reproduce this issue with 2 station(As unavailability of 2 more), but unable to do. We use wlan_AP example with following changes

    // get network configuration
    lRetVal = sl_NetCfgGet(SL_IPV4_AP_P2P_GO_GET_INFO,&ucDHCP,&len, (unsigned char *)&ipV4);
    if (lRetVal < 0)
    {
    UART_PRINT("Failed to get network configuration \n\r");
    LOOP_FOREVER();
    }
    while(1)
    {
    UART_PRINT("Connect a client to Device\n\r");
    while(!IS_IP_LEASED(g_ulStatus))
    {
    //wating for the client to connect
    }
    UART_PRINT("Client is connected to Device\n\r");

    while(IS_IP_LEASED(g_ulStatus))
    {
    //wating for the client to connect
    }
    UART_PRINT("Client is disconnected to Device\n\r");
    }


    With below steps:
    1. Powered up 3200 in AP
    2. switch on wifi on station_1 and connected to AP
    3. Swich off wifi on station_1
    4. switch on wifi on station_2 and connected to AP
    5. Swich off wifi on station_2
    6. goto step 2.

    We repeated steps 2 to 4 15 times. Can you tell us after how many cycles this issue is appearing? Also what changes you have made in wlan_ap code.

    Hi Aashish,

           We change nothing. Please use 4 mobiles to try. And no accurate times, 10 times or 20 times or 30 times. But you can get this issue. 

    Best Regards!
