You do not need to put sudo before './pybombs install gnuradio' as it can
install everything as the local user.

HI guys,
Thanks in advance.
Currently I have been engaged in a project which is based on the
OFDM_benchmark example. I plan to realize a round trip communication
between two USRP2 node. Concretely, I want to control the node A switch to

Hi,
Looks like either the syntax for instantiating multi_usrp has changed
(seems unlikely), or a bug was introduced, likely in 7/2-7/4's recent
gr-uhd refactoring (1eaa96b, 350d285, fe58537, 3c42e79, 691bdaa). Sorry I
