MQTT Client -Reconnection with broker and WLAN is Connected(i.e IP is acquired)

Hi,

I'm trying to reconnect  with broker.In my case CC3200 is connected with mobile hotspot (i.e acquired the IP address) and mobile doesn.t have reliable internet connection. 

When I disconnected with broker i'm using below commands to reconnect again but its fails -

I changed the code in disconnection event as per my need.Here, whenever its get disconnected from broker its comes to this event and here led turns on to show its doesn't have internet but when its goes to BrokerReconnect()  function its not connected with broker again.If it get connected successfully then its led turns off but its not connecting with broker again.
