[Discuss-gnuradio] changing modes during execution

[mjam01]

hey guys,

i'm trying to change from nbfm to am with this function:

def set_mode_am(self,urm):
        #self.connect.clear()
        self.guts = blks.am_rx (self, self.audio_rate, self.quad_rate)
        self.connect (self.src, self.ddc, self.guts, self.mute_audio,
(self.audio_sink, 0))

what can i replace self.connect.clear() with to make it disconnect and
connect to the new mode?

i get this error:

Traceback (most recent call last):
  File "./scandoo_v1.py", line 268, in set_mode_am
    self.connect (self.src, self.ddc, self.guts, self.mute_audio,

    raise ValueError, ("destination endpoint already in use: %s" %
(dst_endpoint))
ValueError: destination endpoint already in use: <endpoint (<gr_block
freq_xlating_fir_filter_ccf (2)>, 0)>


any ideas??
