RTOS/CC3200: WIFI AP mode connection problem

Tool/software: TI-RTOS

Hi,

      with cc3200 STation mode working properly ,but in AP mode from my mobile device ssid detected but not connecting properly connecting...only seeming,for AP mode any connection policy need to set apart from ssid and sl-SEc?

sl_WlanSetMode(ROLE_AP);

/* Restart network processor */
sl_WlanSet(SL_WLAN_CFG_AP_ID, WLAN_AP_OPT_SECURITY_TYPE, 1, (unsigned char *)&val);

sl_Stop(BIOS_WAIT_FOREVER);
mode = sl_Start(0, 0, 0);
