[Discuss-gnuradio] Synchronizing phases between two N200

2012-10-03 Thread Shih Oliver
Hi lists, I'm using a E100 to send a sine wave to two N200 by going through a splitter and I'm trying to synchronize the phases between the signals recieved by the two N200.Both of the N200 have internal GPSDO with the gps locked and the same gps time. However, they are still not in

[Discuss-gnuradio] Build issue on a different machine

2012-10-03 Thread kaushik
Hi Lists, I am quite new to the Gnu radio. We are trying to do spectrum scanning using Energy detection. One of our collegues used gr-modtool to write the signal processing block for it. He build the project using python 2.7.2 and Gnu radio version 3.6.3, make'd and checked into the source tree.

It's not just an offset problem. Even though in the output file, there is a delayed sequence, it doesn't have the right bits. As it has exactly the same period it leads me to believe that it's just a problem of phase sync. Attached is a minimal grc file. Cheers, Fabián On Wed, Oct 3, 2012 at 12:

[Discuss-gnuradio] gr-extras: tuntap : How to use ?

2012-10-03 Thread Iain Young, G7III
Hi Folks, Finally getting around to playing with some of the stuff in gr-extras. Having compiled 3.6.2, and the extras, I found the tuntap block, and was hoping to use it to implement some RF Networking with the GMSK modules. I found the tuntap block, and noticed that it had an input and output

I figured out the problem. There were two things I wasn't taking into account: - The modulator reads bits in MSB order, which means that I should pack them the same way. - There is a bit framing problem (can be solved using packet encoder/decoder). Checked converting both sequences to

Is this the stock rootfs or something custom? Is usrp_e module loaded? Are you using the UHD from opkg or did you build it yourself? If so, did you enable E100 support? -josh On 10/03/2012 05:55 PM, Valentina Aguilar Ocoro wrote: > ...? > > > > _

Re: [Discuss-gnuradio] Initialize a pointer - object

Hi all, Sorry to bother again with this issue. Maybe the question is: Can I pass a pointer as an argument to the block function?. I mean, can I use the block like this: blob_to_stream_impl(const size_t *file) // Pass a pointer to the blob function. Regards, Jose On Wed, Oct 3, 2012 at 4:12 PM
