Hello all
just looking for some help regarding the USRP N210 in GRC.
I'm having a problem with the IP address in GRC.
I have looked around but the only material I have found regarding IP address
relates to setting up the N210 on the network.
That part I have correct.
-> I can ping the device
-> uhd_find_devices returns as it should
-> utilitiy programs (txrx_loopback) work
My problem I think is in integration with GRC.
I have an existing flow that implements my OFDM system (loopback to same
device) that I was using with my USRP1.
All I have done after swapping in the N210 into the loop is populate the
fields in the USRP sink/source block with the N210's address.
I get the following error complaining about the IP address:
/////////////////////////////////////////////////////////////////////////
Traceback (most recent call last):
File "transmitter_gain_freq_test.py", line 226, in <module>
tb = transmitter_gain_freq_test()
File "transmitter_gain_freq_test.py", line 111, in __init__

return _uhd_swig.usrp_source(*args)

/////////////////////////////////////////////////////////////////////////
The generated code is as follows:
self.uhd_usrp_source_0 = uhd.usrp_source(
device_addr="192.168.10.2",
stream_args=uhd.stream_args(
cpu_format="fc32",
channels=range(1),
),
)
self.uhd_usrp_source_0.set_time_now(uhd.time_spec(time.time()),
uhd.ALL_MBOARDS)
self.uhd_usrp_source_0.set_samp_rate(samp_rate)
self.uhd_usrp_source_0.set_center_freq(carrier, 0)
self.uhd_usrp_source_0.set_gain(RX_gain, 0)
self.uhd_usrp_source_0.set_antenna("RX", 0)
With the remaining fields blank or default (works with USRP1)
System:
ubuntu 12.10
GNU radio 3.6.5.1
I'm rather stumped here, any suggestions of change would be much
appreciated.
port number perhaps?
