[Discuss-gnuradio] Re: in-band signaling project overview

2007-10-11 Thread Jeff Brower
George- Ok, I get it. Sounds very promising. A couple of quick questions: 1) What about commands (meta-data) to help deal with latency? For example, 'if you receive such-and-such request, send this ACK'? 2) Does your new FPGA code require the next-gen USRP, with Spartan 3 FPGA? My understa

[Discuss-gnuradio] in-band signaling project overview

2007-10-11 Thread George Nychis
Hi all, I've gotten an e-mail asking what exactly is the in-band signaling project, and since I'm asking for people to help contribute... I think that's a fair question for me to answer :) Overview: We're making significant changes in GNU Radio and the USRP FPGA to create a control channel

Hey all, There have been many people popping their heads in and out of the list and sending me private e-mails to check the status of the in-band project, as most of you are interested in building MACs or using those wonderful new timestamps so far :) Here's your chance to help the project and

2007-10-11 Thread Jared Jensen
Does anyone know why I get "fusb::_reap: Interrupted System Call" fairly frequently? There are no overruns, and my data seems good, but I keep getting this error. If it's meaningless, is there a way to suppress it? Jared _ Boo!

Hi, Thanks everybody, this thread helped me a lot to understand the multi antenna cabability of gnuradio. I tried to run the multi_scope.py on a cingle USRP having two rfx2400 daughterboards with following changes in current multi_scope.py: 1) On line 44: nchan changed to 2 from 4 2) On Line 67: "

I'm sure you are right about the gui taking the majority of the cycles, but it's the real-time feedback that makes gnuradio so attractive. Ideally one would beable to switch them on and off as needed during operation of the program, which it is my understanding will be possible with the impleme
