hi all
i would like to define my own format for decoding CC1101 packets
sync word : d391h
packet length : 1 byte
can i easily derive the header_format_base in python and add it in my top
block or do i need to write C++ code and recompile gnuradio ?
thanks

hi
i does not work because the packet header parser expect an
"packet_header_default" object instead of a "header_format_base" object

Hi all
i placed an import block into grc but i still get this error
Param - Value(value):
Value
"f4gsw.header_format_cc1101(digital.packet_utils.default_access_code, 1)"
cannot be evaluated:
'module' object has no attribute 'header_format_cc1101'
i created the module f4gsw and i added
~header_format_cc1101();
why python throws me this error ?

hi all
i created a "noblock" OOT module
child class of header_format_base
no XML installed (edited the Cmakelists file in grc folder)
compilation OK
installation OK
nm -C -u lib-*** OK
python import OK
in top_block.py i have these lines :
self.hdr_format = hdr_format =
hi all
i'm trying to derive the header_format_base with no success
i created a new module with modtool and the "no block" profile
i copied and modified the "header_format_default" sources but i get swig
error
telling me that sptr is not defined
did someone ever managed to write its own header
):
Value
"f4gsw.header_format_cc1101(digital.packet_utils.default_access_code, 3,
Const_PLD.bits_per_symbol())" cannot be evaluated:
name 'f4gsw' is not defined
thanks

Hi
I would like to decode a simple GFSK packet
here is the packet structure :
preamble : AAh x 4
sync word : D391h
length byte : 1 byte
payload : 1 to 64 bytes
CRC : 2 bytes
TX : arduino + CC1101 module, 2GFSK, 100kbps, excursion 50kHz, carrier 433
MHz
RX : RTLSDR
until now i was able to

Hi All
did someone make the test_corr_est.grc example work properly recently ?
i tried the 3.7.13 gnuradio version on linux, macos and windows
in all versions the output of the correlation estimator block is really a
mess
this block put tag even if there is no signal at all, with corr_est = 0
19 matches
