It might help if you could post the exact flowgraph that you are running, as well as the source code of the main python program. Aug 20, 2021 14:15:30 Martyn van Dijke : > Hi Jeff, > > Thanks for the quick response. > > I have tried running the flowgraph.py manually but not after three times,

Hi Jeff, Thanks for the quick response. I have tried running the flowgraph.py manually but not after three times, this is a good point and will try it this weekend to see if that changes the behavior. The behavior does not change based on how long the processes are runned, adding delays does

Problem with GFSK Mod and Demod example from wiki

Hello everybody, I want to do some simple test of GFSK modulator and demodulator. I used an example from wiki - https://wiki.gnuradio.org/index.php/GFSK_Demod . I copied flowgraph, but my Time sink shows me only signal on input of modulator - output signal is really weird - some peaks... Why I can

Sounds like you're running out of some resource. What happens when you run flowgraph.py manually (piping in some fixed data if needed) instead of executing it with Popen? Does the behavior change based on how quickly the processes are run? Can you put in a long delay between packets? Are you doi

Re: Conversion from char (byte) to float

There are two conversion blocks called "Char to Float" and "UChar to Float" - I guess you are looking for the second one. Both take "Byte" as input. Am 20.08.21 um 11:24 schrieb Marcin Puchlik: Conversion from byte to float works wrong (in my opinion) for byte variables greater than 127. Corre

Conversion from char (byte) to float

2021-08-20 Thread Marcin Puchlik
Conversion from byte to float works wrong (in my opinion) for byte variables greater than 127. Correct me if I'm wrong: char/byte range is from 0 to 255 (included). In GNU Radio, after conversion from char/byte variable type (that is greater than 127) to float, the result is negative. Seems like ra
