CC3220: WPA2 enterprise with SL_ENT_EAP_METHOD_PEAP0_MSCHAPv2 raise callback disconnect with reason 154

Part Number: CC3220

Hi,

I am trying to implement the WPA2 enterprise connection on our device which is using the cc3220.

When using WPA2 enterprise I get the event SL_WLAN_EVENT_DISCONNECT in the callback SimpleLinkWlanEventHandler with the error reason 154. I cannot find the error reason 154 in wlan.h.

More infos:

• I have put a dummy (correctly formated) certificate in sys/cert/ca.der
• I have tried with both the wlan profile and the direct connection with same result.
• The same thing works on our other product which is using cc3200 so the radius server and AP are working fine.
• The wpa2 personnal is working fine on the cc3220

My questions:

• What is the error reason 154? 
• Is there something obviously wrong with my configuration below?

Here is the code snippet where I configure the connection: 

SlWlanSecParams_t secParams;

SlWlanSecParamsExt_t eapParams;

secParams.Key = "thepassword";
secParams.KeyLen = strlen("thepassword");
secParams.Type = SL_WLAN_SEC_TYPE_WPA_ENT;

eapParams.EapMethod = SL_WLAN_EAPMETHOD(SL_PEAP0, SL_MSCHAP

SL_WLAN_CC31XX_DEFAULT_CIPHER,
SL_WLAN_CC31XX_DEFAULT_CIPHER);
eapParams.User = "user";
eapParams.UserLen = strlen((const char *) eapParams.User);
eapParams.AnonUserLen = 0;



_u8 param = 1; /* 1 means disable the server authentication */

ret = sl_WlanSet(SL_WLAN_CFG_GENERAL_PARAM_ID,SL_WLAN_GENERAL_PARAM_DISABLE_ENT_SERVER_AUTH,1,&param);
if( ret )
{
ERROR_PRINT("Could not configure");
}

ret = sl_WlanProfileAdd((const signed char*) wificreds->ssid, strlen(wificreds->ssid),forced_mac, &secParams ,&eapParams,7 ,0);
