Re: [Discuss-gnuradio] gr-usrp library

Hi Eric,
 I am facing a weird problem. 
 
 I was trying the rx.py and tx.py gmsk scripts in gnuradio-examples/python/gmsk - this is the old gmsk implementation. I am getting the character stream I sent using tx.py at the receive side. But if I disable the gui (using the --no-gui option), then I do not get any output. 
 
 I couldnt find any reason for why this is happening. I thought that maybe its because of some kind of a time delay. So, I ran rx.py first and then tx.py, but if the --no-gui option is used I do not get anything in the file_sink at the rx side.
 
 Any ideas as to why this is happening?
 
 Thanks
 Gesly
