Hi,
I did the following:
1) in linux terminal I create a fifo file as :
$ mkfifo in
2) in gnuradio I did:
file source (file name : in)-> throttle -> file sink (output file: out.txt)
then for running, I did the following:
1) run the flowgraph
2) in terminal, I run
$ cat > in
then only if I wrote a large number for characters, those characters are transferred.
for example if I wrote 10 bytes in fifo in to transmit them, any byte is not written in the file out.txt. while, if 15000 bytes are written in fifo in the some of these 15000 bytes are transferred to out.txt but not all of them.
it seems to me that fifo in gnuradio does not transfer each byte alone, is saves a number of bytes as a packet then it send them together.
my question is :
1) how to transfer each byte alone in my flowgraph example using unix pipe?
2) if I can not transfer each byte alone, what is the size of packet that are buffered and the transferred together?
3) If the last bytes are less than packet size, then they are not transferred. therefore, how I can I transfer them?
if I have to do padding then I have to know the size of the buffer or packet? Is it fixed or not?
Thanks for your time and help
Best regards
