[Discuss-gnuradio] Error using block UHD AMsg Source

[Jose Torres Diaz]

Hi All, 

I'm checking the functionality of the block "UHD AMsg Source" using the USRP N210. The device is correctly detected as you can see:

uhd_find_devices 
linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.003-221-g9d6f9492

--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
    type: usrp2
    addr: 172.17.3.140
    name: 
    serial: E0R17TCUP

I've attached a screen-shot of the GRC file. When I run the flow graph, I get the following error:

Traceback (most recent call last):
  File "/home/asrpuser/Desktop/Jose Torres Material /top_block.py", line 54, in <module>
    tb = top_block()
  File "/home/asrpuser/Desktop/Jose Torres Material /top_block.py", line 33, in __init__
    self.extras_uhd_amsg_source_0 = gr_extras.uhd_amsg_source(device_addr="add=172.17.3.140")
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/extras/extras_swig.py", line 5384, in make
    return _extras_swig.uhd_amsg_source_make(*args, **kwargs)
TypeError: in method 'uhd_amsg_source_make', argument 1 of type 'uhd::device_addr_t const &'

Anyone has seen an error like this before?, How can  I solve/workaround this error?

Thanks a lot for your help, 

Jose.
