[Discuss-gnuradio] Automatic file generation

[farid mihoub]

Hello,

 

I am trying to generate multiple files with formatted names using python, for  a later offline processing.

The code below does the job for me but:

1- everytime a new class(flow graph) is created.

2- definition of the file_sink and its connection to the previous block must be inside the set_file_name function.

 

Purpose:

The flow graph is processing a limited number of samples, there is no infinite run, so I want

to rerun the flow graph without making new objects or connections and with dynamically changing parameters.

 

the relevant part of the code:

    ...
    def set_file_name(self, name):
        self.blocks_file_sink_0 = blocks.file_sink(gr.sizeof_char*1, name, False)
        self.connect((self.blocks_throttle_0, 0), (self.blocks_file_sink_0, 0))
        self.blocks_file_sink_0.set_unbuffered(False)
      
def main(top_block_cls=top_block, options=None):
    for i in range(10):
        tb = top_block_cls()
        tb.set_file_name('./out'+str(i)+'.dat')
        tb.start()
        tb.wait()
...

 

Any Ideas?

 

Thank you.
