Hello,
I understand that I have use online ASCII to binary converter and for that I am using below online converter.
But I am facing an issue, while I am transmitting repetitive pattern such as 1100, 1010 , the data stored in the file after mod-demod is almost similar( only some initial bits are changed) . Please check the screenshot attached.
But when I am transmitting some random pattern instead of repetitive using file source, I am not receiving the same pattern, while I am converting the stored ASCII to binary using converter.
I have sent the GRC file in previous mail. Kindly let me know, where is the problem?
Waiting for your positive response.
With Best Regards,

Hi Maitry - if by update you mean dumping a binary file as binary
instead of hexadecimal, then on Linux use
xxd -b <infile> <outfile>

Hello experts,
Any updates?
Ok, thanks.
Hello,
Please ignore the previous grc file. please find
attached the correct grc file.
Hello,
Please find attached grc file for reference.
I have done trial and error by converting the
output file into online ascii to binary
converter, but it provides random output.
Please guide which binary viewer I need to
use in check the data in 1 and 0 format(binary)
?
Or maybe use a gr-baz any sink to
view bits?
Hello
Maitry,
The File Sink is not producing a text file,
it is the raw binary data.
You need to look at the contents of the file
using a binary viewer.

Derek
