Re: [Discuss-gnuradio] HELP with "packet header parser"

[Cinaed Simson]

I'm assuming the reason you're not looking at the rx_ofdm.py code is
because you don't have the rx_ofdm.py code.

You can use

  grcc -d . rx_ofdm.grc

to generate the python code.

Okay, well you'll have to post your flowgraph and I'll try to help you.

Or post your python code and maybe someone on the list may be able to
help you.

The error message at the bottom indicates the wrong number arguments.

  digital.header_format_default('1101001110010001', 0)

Try

  digital.header_format_default('1101001110010001', 0, bps)

where bps is the number of bits per symbol for your problem.

See

   Default Header Format Obj.

in the grc.

[Discuss-gnuradio] HELP with "packet header parser"

[Alban Meffre]

hi all

i try to figure out how to use the "packet header parser" block
as a formatter i use
"digital.header_format_default('1101001110010001', 0)"

when i launch i get the error
"
Traceback (most recent call last):
  File "/Users/alban/gnuradio/top_block.py", line 146, in 
main()
  File "/Users/alban/gnuradio/top_block.py", line 134, in main
tb = top_block_cls()
  File "/Users/alban/gnuradio/top_block.py", line 71, in __init__
self.digital_packet_headerparser_b_0 =
digital.packet_headerparser_b(hdr_format_dec_0)
  File
"/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gnuradio/digital/digital_swig2.py",
line 2651, in make
return _digital_swig2.packet_headerparser_b_make(*args)
NotImplementedError: Wrong number or type of arguments for overloaded
function 'packet_headerparser_b_make'.
  Possible C/C++ prototypes are:

gr::digital::packet_headerparser_b::make(gr::digital::packet_header_default::sptr
const &)
gr::digital::packet_headerparser_b::make(long,std::string const &)
"


in the "rx_ofdm" example supplied with gnuradio, the  "packet header
parser" use the formatter  "header_formatter.base()"

i do not find any documentation about the base() method
as you can see the doxygen is empty
https://www.gnuradio.org/doc/doxygen/classgr_1_1digital_1_1header__format__base.html#a5a7b2939707146f2b28d7e91e04103c2

if i add ".base()" to the formatter in my top_block i get an error too

please someone can explain me hox to use this block ?
thank you all
