How to subscribe IBM Watson IOT Platform with CC3220s launchpad and Code Composer Studio?

I have been trying to send messages to IBM IOT Platform using CC3220s Launchpad and Code Composer Studio cc32xx SDK, watson_mqttclient_CC3220S_Launchxl_tirtos_ccs project.

---

I can send the messages to quickstart broker.
However, I got:

• Invalid userID () for device auth:
  ClientID='d:u45vsd:ti-simplelink:9884e34e0611',
  ClientIP=178.241.108.68
  Connection Log Message on IBM Watson IOT Platform
• CONNACK:
  Connection Error: 5
  Connection to broker failed, Error code: -5
  BRIDGE DISCONNECTION
  Error on CCS serial terminal

---

I have done following changes on CCS mqttclient code and IBM Watson IOT Platform:

1. I have changed the security level as "TLS Optional" on the security options IBM Watson IOT Platform and I have added new device with following informations:

   Organization ID : u45vsd
   Device Type : ti-simplelink
   Device ID : 9884e34e0611
   Authentication Method : use-token-auth
   Authentication Token : zzzzzzzzzzzzz

2. Following codes were changed in network_if.h:

   define SSID_NAME "Netmaster EB75-G"
   define SECURITY_KEY "password"
   define SECURITY_TYPE SL_WLAN_SEC_TYPE_WPA_WPA2

3. Following codes were changed in mqtt_client_app.c:

   define SERVER_ADDRESS "u45vsd.messaging.internetofthings.ibmcloud.com"
   char ClientId[64] = "d:u45vsd:ti-simplelink:9884e34e0611";
   const char *ClientUsername = "use-token-auth";
   const char *ClientPassword = "zzzzzzzzzzzzzzzzzzz";
   sprintf(ClientId, "d:u45vsd:ti-simplelink:%02x%02x%02x%02x%02x%02x", macAddress[0], macAddress[1], macAddress[2], macAddress[3], macAddress[4], macAddress[5]);

What am I missing?
Any help will be appreciated.
Thanks in advance.

I have solved my problem with uncomment lines below:

#define CLNT_USR_PWD
#define SUBSCRIBE
