Re: [Discuss-gnuradio] grc-mimo setup

[Martin Braun]

This was a UHD bug we fixed a couple of weeks back. If you're using 
git/master, you can just git pull, rebuild UHD and it will work.

Otherwise, you can set otw_format=sc16 in the streamer args and it will 
solve the problem as well.

Cheers,
M
