After putting the device in AP mode and when I try to connect with it, it is not connecting, from the client side(ubuntu machine), the output is as follows:

[  301.180717] wlp1s0: authenticate with 4c:24:98:d3:40:5b
[  301.195695] wlp1s0: send auth to 4c:24:98:d3:40:5b (try 1/3)

Tried with mobile also, it is struck in getting ip address for some time and disconnects:

The code for configuring the device in AP mode is as follows:

slStartRetVal = sl_Start(0, 0, 0);
if (slStartRetVal != static_cast<_u8>(ROLE_AP))
{
int16_t Status = sl_WlanSetMode(ROLE_AP);
slStartRetVal = sl_Start(0, 0, 0);
}

retVal = sl_WlanSet(SL_WLAN_CFG_AP_ID, SL_WLAN_AP_OPT_SSID,
strlen(Ssid), (const _u8 *)Ssid);

retVal = sl_WlanSet(SL_WLAN_CFG_AP_ID,
SL_WLAN_AP_OPT_SECURITY_TYPE, 1, (const _u8 *)&val);

retVal = sl_WlanSet(SL_WLAN_CFG_AP_ID, SL_WLAN_AP_OPT_CHANNEL, 1,
(_u8 *)&channel);

retVal = sl_WlanSet(SL_WLAN_CFG_AP_ID, SL_WLAN_AP_OPT_PASSWORD,
strlen(password), (const _u8 *)password);


/* Check if sl_Start is already started or no error*/

if ((slStartRetVal >= 0) || (slStartRetVal == SL_RET_CODE_DEV_ALREADY_STARTED))
{
retVal = sl_Stop(SL_STOP_TIMEOUT);
slStartRetVal = sl_Start(0, 0, 0);
}
