BBN 802.11 code - hier_block2

GNU Radio
1

I do now have the BBN code working with hier_block2. It looks like the
problem I was encountering was the message queue was inside a hier_block

  • but moving it out to the top_block (i.e. bypassing bbn_80211b_pkt.py,
    and just creating the message queue and calling bbn_80211.py directly)
    works. Is this a feature of hier_block2, or a bug?

For those that are interested, I’ve checked the changes into my
developer branch on CGRAN. Note - I have only tested receiving 802.11b
(1Mbps) packets, I have not tested transmitting at all.

I am able to decode some packets through the USRP1. Bear in mind, this
is not the full-bandwidth (SPAN) 802.11b decoder. Although porting that
over to the hier_block2 API should be basically the same. In the
meantime, I welcome any other testers looking at 802.11b to try my code
out.
