[Discuss-gnuradio] Help, dont understand gr.hier_block proper use |

Hello all,
I have been trying to make my own version of the gmsk2 benchmark for ask
modulation. I am getting the following error:
Using RX d'board A: <none>
self = <mrts.blksimpl.ask.ask_demod object at 0xb7a70dcc>
Traceback (most recent call last):
File "./benchmark_ask_rx.py", line 128, in ?
main()
File "./benchmark_ask_rx.py", line 121, in main
fg = my_graph(options.rx_subdev_spec, options.decim, rx_callback,
options.log)
File "./benchmark_ask_rx.py", line 81, in __init__
rx_callback, log)
File "./benchmark_ask_rx.py", line 62, in __init__
threshold=threshold)
File "/home/mrobitaille/GRworking/MRTS/src/lib/mrts/blksimpl/ask_pkt.py",
line 74, in __init__
self.ask_demod = ask.ask_demod(fg, *args, **kwargs)
File "/home/mrobitaille/GRworking/MRTS/src/lib/mrts/blksimpl/ask.py",
line 75, in __init__
input_rate = self.adc_freq() / self.decim_rate() # 64 MS/s // 250 =
AttributeError: 'ask_demod' object has no attribute 'adc_freq'
I believe its due the the gr.hier_block.__init__.
Per the DShen tutorial states "Either head or tail may be None indicating a
sink or source respectively.". The gmsk2_demod(_pkg) modules dont seem to
follow this. I would think these blocks should be sink but seem to be
source per DShen statement (tail is None). I also see that there is times
where both are etheir none or the same.
Could someone please clarify?
Also, could someone look at my code and see why I am getting the error.
Thanks,
Mike
