Re: [Discuss-gnuradio] PMT: vector of vectors of ints

AFAIK that's only used for coloring and sanity checking sizes before running a flowgraph. You should be able to use your matrix datatype with a vlen of your total matrix size. float N*M On Wed, Mar 1, 2017 at 4:04 PM, devin kelly wrote: > Is there any way to create a vector of vectors of ints

[Discuss-gnuradio] PMT: vector of vectors of ints

Is there any way to create a vector of vectors of ints with the PMT library? I'm trying to make a C++ GR block that takes in an NxM matrix. For GRC all the types are listed at the link below, none really fit my model. https://github.com/gnuradio/gnuradio/blob/d4bb541ec1ec93446ecfa53948a1a6f995ff

[Discuss-gnuradio] Upcoming GR tutorial and meetup (Dyspan in Baltimore, MD)

Hi all, Once again, I expect there will be a lot of GNU Radio use at DySPAN next week in Baltimore, MD. Let me know (you can reply to just me) if you're interested in a meet up with other GNU Radio minded people after a conference day. I'm currently thinking Tuesday night. Also, be sure to check

Re: [Discuss-gnuradio] HackRF + osmocon, RX works but TX doesnt

I have just seen the video. I did not know that. So if you have a 20dB RF amplification and you have a mobile phone near the antenna of your receiver, it can destroy your receiver. I guess this is of application also to bladeRF, RTL-SDR, etc. regards El

Re: [Discuss-gnuradio] image trasnfer in gnu radio

Hey, I don't know about any example in particular but generally, you would need to implement some higher layer functionality on top of your PHY of choice (for example the OFDM PHY builtin to GNU Radio). Something like TFTP comes to mind. Essentially you need a way to tell the receiver the length o

[Discuss-gnuradio] image trasnfer in gnu radio

Hi. If I want to transfer, say an image, from one SDR to another using GNURadio. how will tell the flowgraph to stop running when it reaches the end of the file? It would be helpful if there is any example in this. Regards, Sagnik Basu B. Tech | 2013-2017 Dept. of Electronics and Communication N

Re: [Discuss-gnuradio] HackRF + osmocon, RX works but TX doesnt

Yes, you can kill any receiver by overloading the RF amplifiers. Best regards, Marcus On 03/01/2017 04:10 PM, Fernando Peral wrote: > you mean you can break the hackRF if you use much gain? > > > El 28/02/17 a las 22:57, Cinaed Simson escribió: >> Also, you should get to know your HackRF so you

Re: [Discuss-gnuradio] Testing Message Based Blocks

Ooo, I hadn't even thought about that. Thank you!! I'm still interested in why the Python block doesn't work 'correctly' while the C++ block does, so if you do get some time I'd really be interested in your findings. Thanks!! On Tue, Feb 28, 2017 at 11:38 AM, Marcus Müller wrote: > Hi Dav
