Hi everyone,  
I’m starting a application with Q64 in order to DTMF Decode. I an using the sample application od the M2M Studio.  
it is working whith DTMF code and blank duration greater than 200 miliseconds. I need decodes digits (and blank space) of 50 miseconds.  
This situation the application decodes only first digit. How I can do working with signals DTMF of 50ms? Can someon help me?

thank
