Hi everyone,
New to GNUradio and OP25. I have the OP25 block installed in GNU Radio Companion and can build a flow graph with no problem. When I try to execute the flow graph I get this error:
Traceback (most recent call last): File "/home/aaknitt/Documents/top_block.py", line 53, in <module> tb = top_block() File "/home/aaknitt/Documents/top_block.py", line 34, in __init__ self.op25_decoder_0.create() File "/usr/local/lib/python2.7/dist-packages/baz/op25.py", line 65, in create self.p25_decoder = op25.decoder_ff(self.op25_msgq) AttributeError: 'module' object has no attribute 'decoder_ff'
I'm guessing this is because I don't have something installed properly, but I can't put my finger on how to remedy the problem. Any advice or suggestions would be appreciated.
Regards,
Andy
I don't normally build the GRC stuff but I am stoked at Balint's progress there. So, with that warning here are some thoughts... Firstly, decoder_ff isn't the way to go. We should be using decoder_bf with a slicer on its input to convert the floats to symbols. That's what the python code does. Secondly, it might just be a PYTHONPATH issue. Can you import the op25 package from the python command line? If you can get it in Python then I reckon it should work in GRC.

I was just about to say "yes, I can import op25 from the python command line" since I'm almost 100% certain I tried that yesterday after installing op25. However, I just tried it again and it's not working, so I think you're on to something with the PYTHONPATH issue. I'm clueless about how to fix it though, any tips?
Thanks,
Andy

Ahh...and now Balint has reminded me that yesterday I was using:
from baz import op25
That still works today.

Hi folks,
Sorry my bad (I think) - please update gr-baz and try again.
