Re: [Discuss-gnuradio] GMSK Demodulator -- Assertion 'imu>=0" failed.

[Fasika Alemayehu]

I am using GNU radio 3.1.1 but I have been using the block blks2. Now I am using blks2impl and the error is gone. But I am now facing a new problem.
----------------------------------------------------------------------------------------------------------------------
 "/usr/local/lib/python2.5/site-packages/gnuradio/gr/basic_flow_graph.py", line 84, in coerce_endpoint
    raise ValueError, "Not coercible to endpoint: %s" % (x,)
ValueError: Not coercible to endpoint: <gnuradio.blks2impl.gmsk.gmsk_demod object at 0xb649deac>
------------------------------------------------------------------------------------------------------------------
Here is the code:

from gnuradio import gr
from gnuradio.blks2impl import gmsk
from optparse import OptionParser
from gnuradio.eng_option import eng_option
import struct

class graph(gr.flow_graph):

    def
 __init__(self):
        gr.flow_graph.__init__(self)

        filename = '/home/fasika/Desktop/Binary'
        outputfilename = "demod"

        self.src = "" filename)
        demod = gmsk.gmsk_demod()
        self.dst = gr.file_sink(gr.sizeof_char, outputfilename)
        self.connect(self.src, demod, self.dst)
     
if __name__ == '__main__':
    try:
        graph().run()
    except KeyboardInterrupt:
        pass
