Yes, converting a discontinuous, message driven flow to a continuous flow of samples really is what gr-eventstream does! On 08/29/2017 06:02 PM, Mehmet Ozcelebi wrote: Thanks for your kind help. BTW, is there a proven Flowgraph that can send qtgui_edit_box_msg or discontinous data through a c

Then, you very likely want to pad your data with zeros; there's Tim O'Shea's gr-eventstream, which is designed for that operation! Best regards, Marcus On 08/29/2017 04:34 PM, Mehmet Ozcelebi wrote: I just want to transmit scrambled data continously, even if there is no input data. For conti

Hi Mehtap, unlike your FPGA, the GNU Radio blocks don't work data-synchronously. So, they simply won't give you any output if you don't call them with input! Maybe you could elaborate on what you mean with "got stuck"? So, I'm not quite sure what the problem actually is, albeit I'm pretty su

Some years ago I implemented a scrambler block in FPGA for a transmitter. It produced an output every clock cycle. Now I try the GNU Radio scrambler/descrambler blocks. They work great if the data flows continously like from a Vector source or File. However if I have a discontinous source like a te
