SV: [Discuss-gnuradio] BBN 802.11 USRP2 code, failing on git master

[Ulrika Uppman]

If you change the io_signature(1,2, ...) to io_signature(1,1, ...) I believe it will work.

Hi all,

Has anyone gotten the usrp2_version branch of the BBN 
802.11 code on CGRAN working with the current git master?  Whenever I try 
to run the receiver, I get:

$ ./bbn_80211b_rx.py

recent call last):
