Re: [Discuss-gnuradio] Generating hexadecimal data and printing directly on the terminal

[CEL]

Hi Guilherme,

1) "unpacked to packed" is probably what you want!
2) don't do that, unless you really want to "humanly read" that output.

Re 2): I just happen to explain why you shouldn't do that and how you
can circumvent the need to do that. In essence, the standard output (at
this time, at least) is not guaranteed to not be used by other blocks
and the GNU Radio scheduler itself. So, you  get into trouble if you
want to parse that.
Instead, use a file sink and a `mkfifo`-generated named pipe.

Best regards,
Marcus
