Hi, all,
I am trying to communicate between two USRP1 with the bbn_80211b_tx.py and bbn_80211b_rx.py. My OS is Ubuntu 10.10, but I have no idea what is my GNU Radio release(if anyone can help me to find out it, it will be very appreciated.)
First, I tried to transmit the getty.txt. I run the command line as following:
bbn_80211b_tx.py
and got the output as following:
Using TX d'board A: Flex 2400 Tx MIMO B
>>> gr_fir_ccf: using SSE
spb: 8
interp: 32
Sending pkt 0
sending...
Sending pkt 1
sending...
Sending pkt 2
sending...
then it was just stuck there, no response at all, even I make ctrl+c. I had to kill the process to terminated it.
By reading
the code, I guessed the problem is related with the message queue, and I modified the message limit from 2 to 5, then it was stuck on 'Sending pkt 5'.
So, I guessed the problem is, the packets in the message queue were not sent out at all, so when the message queue reached its limit, it just stopped. I have tried to look around for any possible resolution but didn't get any.
Has anyone encountered the same problem before? Any suggestions will be very helpful!
Thank you in advance!
