Sorry, I didn't mean to imply you needed the stream to tagged stream block to make it work. I just put in at the beginning so I could use the tag debug as a brute force search to find out what was blocking the flow. There are two sequential tag blocks - the correlate correlate access code-tag from gnuradio and a block from gr-satellites - I would guess that is all you need. Select "pass thru" on the stream to tagged stream block - it should still work. -- Cinaed > > > With Best Regards, > Maitry Raval, > R& D engineer|Azista Industries Pvt Ltd| 079-40605800|www.azistaaerospace.com > > ----- Original Message ----- > From: "Cinaed Simson" <cinaed.sim...@gmail.com> > To: "discuss-gnuradio" <discuss-gnuradio@gnu.org> > Cc: "Maitry Raval" <maitry.ra...@azistaaerospace.com> > Sent: Thursday, January 10, 2019 1:21:34 PM > Subject: Re: [Discuss-gnuradio] Regarding correlate access code-tag block > > Hi Mailry - I was able to get it run. > > I used the "correlate access" block from gnuradio - my installation of > gnuradio didn't like the block in your flowgraph. > > And then I had to install the python module "construct" in order to get > the flowgraph to run. > > In order to get the flowchart to work - at least in the sense of filling > up the output.txt file - I added a "Stream to Tagged Stream" block and > define a consist tag to get the Tag Debug block to work. > > Also, I had to remove the "unpack" block before the PSK modulation, > added a "Unpack K=1" block just after the PSK demodulation - and I set > "Generate Options" to "No Gui" in the Options block. > > -- Cinaed > > > > On 1/8/19 12:40 AM, Maitry Raval wrote: >> Hello, >> thanks for your guidance. >> I have also attached the grc file, input/output files and python file for >> your reference. after adding tag debug, still didn't get any output.
