Hi Jason,
thanks but I am a little confused.
I would say it is in the same process since I have sink and source in the same
GRC setup. The failure shows up when the generated python script instantiates an
UHD devices the second time as far as I understand.
Is there any combined UHD_usrp_sink/source block for GRC or how is this to
be done practically?
Thanks
Ralf
