I've just updated my system and found a problem when trying to use the uhd_mimo_sink: AtributeError: 'module' object has no attribute 'mimo_sink'. I don't know if it has to do with some mistake during the installation progress and this block is missing or it is something else. Referring to this I would like to know if someone who has already implemented a mimo system could tell me which sink/source blocks should be used.I have a MIMO cable and I guess the smartest is to use this uhd_mimo_sink and uhd_mimo source, but it may work too using two simple uhd_usrp_sink and configuring one of them as a slave as it is explained in the application notes, is it right? I would like to know if someone has experience on that and could me to use the best option. Thank you very much in advance! any advice would be great!
