Re: [Discuss-gnuradio] TunTap Interace for GNU Radio IEEE 802.11 a/g/p module

Hi Bastian, Thanks for your wonderful project. I have the same question that bothers me a lot. I have tried to set up the TUN/TAP things many days but I still cannot get the result that you have got in your example video, such as getting some packets from or to another terminal. I followed the

[Discuss-gnuradio] XML parameter checking

What would be the best way to make sure the user enters a parameter that is a multiple of 8 in the GRC XML file?  My first thought is this might do the trick, but seems there is no mod function for XML.  Any suggestions? $psize % 8 = 0 or $psize mod 8 = 0 Thanks in advance, Mike

[Discuss-gnuradio] Source of event_time in gr-eventstream

Hi all, I'd like to know the source of the value used for event_time in gr-eventstream. Is it the time at the USRP? If I give 2 USRPs the same time source, and then they see the same event, will the same time show up on both streams? I've attached a screen-shot of a part of the flow I use,

Re: [Discuss-gnuradio] Demodulation of Intermittent QAM Signal

Hello Ernest Fardin: As you thought, synchronization loops in the PSK/QAM demod blocks may wander off if you input noise into those blocks. I asked a same question before, and the answer was not to feed in any data to the QAM demod block when you think the transmitter is not on. I did not try

[Discuss-gnuradio] Python Block module file location

I have been experimenting with the Python Block (in core>misc) for something I was trying to gen up quickly.  I have it working, but it seems to like creating random file names for the "block" and storing them in /tmp. Is there anyway to point to a different file in a different location and

[Discuss-gnuradio] 802.15.4 Frame sync confusion

Hi, If my understanding is correct, most of the 802.15.4 receiver implementations perform frame synchronization i.e. find the start of the frame using the preambles which are nothing but 8 zeros(each of which is further converted to 32 bit chip). This is done after the OQPSK symbols (complex

[Discuss-gnuradio] Missing block

Hello, I just downloaded gnuradio on my Mac using the wiki page to download it using macports. I have the application up and running and trying to do some tutorials and examples to get familiar with the layout. I noticed I am missing blocks like the variable slider, scope sink and more. I was

[Discuss-gnuradio] Implementation of TDMA scheme on GNU radio using USRP

What is the procedure of implementing TDMA scheme on GNU radio using USRP? I want to implement TDMA scheme using two SDR as a transmitter and the third one as a receiver. The requirement is that first transmitter sends some data to the receiver for first 10 seconds and then after a delay of two
