[Discuss-gnuradio] RX channel 1 out of range for configured RX frontends

[SUGANYA M]

Hi All,

I am using GNU Radio Companion 3.7.5 and USRP N210.

When I implemented a simple flow graph of SIMO system with two channels using USRP source block ( attached grc flow graph snapshot for reference),

I am getting following error:

Traceback (most recent call last):
  File "/home/student/SUGAN/ONE_TWO.py", line 130, in <module>
    tb = ONE_TWO()
  File "/home/student/SUGAN/ONE_TWO.py", line 72, in __init__
    channels=range(2),
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/uhd/__init__.py", line 122, in constructor_interceptor
    return old_constructor(*args)
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/uhd/uhd_swig.py", line 1740, in make
    return _uhd_swig.usrp_source_make(*args)
RuntimeError: LookupError: IndexError: multi_usrp: RX channel 1 out of range for configured RX frontends

Can anyone help me to fix this error?

Thanks in advance
