Hi all,, I read the [Discuss-gnuradio] and know that gr.hier_block is gone in current GNU Radio. http://www.mail-archive.com/discuss-gnuradio@gnu.org/msg12193.html I used the command: svn co https://www.cgran.org/cgran/projects/bbn_80211/trunk bbn_80211 I checked out the bbn trunk and got the codes only have gr.hier_block. The codes have not been updated for 5 months. I am wondering if anyone maintains the codes? I browsed the source at the link https://www.cgran.org/browser/projects/bbn_80211/branches and found that there is a usrp2_version which all files have been coverted to the hier_block2 format. However, I only have USRP1s. Do I need to convert all the codes in the trunk from gr.hier_block to gr.hier_block2 by myself or I can just use the examples in the usrp2_version? Or I should buy USRP2s? Thank you, Jane
