OAD binary size

Hi All,

I have integrated DFU service into my application. I am successfully able to use OAD so far. Today I have added a piece of code to my application. So, my binary size has been increased. 

After transfer this binary to my device, application hangs and not even advertising DFU or my application services. 

What could go wrong here?  I assume if the app is not properly downloaded, it supposed to advertise DFU services. But my application hangs somewhere. 

Please help. 

Regards

Lakshmi
