Hi
i spent the past few weeks studying the gnuradio blocks c++ source codes,
the doxygen documentation, and the provided examples (specially packet_tx
and packet_rx ones)
and eventually i managed to understand how packetized transmission, tags
and messages work
it was easer than i thought
Hey,
not sure if this still works but I've worked on a CC1101 receiver a
while ago. Have a look here [1] if you're interested.
Cheers

concerning the documentation :
IMHO
i can't blame anyone to have written the documentation in C++ or Python. in
my early days of a C code dev i used to write the doc in raw C code if no
doc at all
do you know why ARDUINO or RASPBERRY PI have become
Hi Alban et al:
Great RTFM graphic!
gnuradio’s documentation could indeed be much better: this is a discussion
topic at conferences and meetings. I had the same issues a couple of years ago
when I was brand new.
Unfortunately, for undocumented blocks, or those ones where the docs are not
Happy new year everyone !
i would be glad if someone explain me how to use the HPD block, how do i
setup messages with PMT blabla, and what is to packet_len tag and how to
pass the packet length etc.
the packet_rx exmple work with OFDM and has nothing to do with simple FSK
frame decoding
i will

Hi Ed,
My solution makes a PDU of the maximum
But this would only work well if there is enough gap time and/or preamble bits
and/or fill bytes between the packets. Otherwise, you will consume and discard
the beginning of the next packet.

Hi,
Besides using the Header Payload Demuxer as Julian suggested, a simple
trick when the packet size is unknown but limited to a (not very large)
maximum size is to cut a PDU with the maximum packet size and then throw
away everything you don't need.
I have a CC1101 decoder in gr-satellites
Hey Bob,
there is plenty of documentation on this topic you can check out under
[1,2].
Especially, the Header Payload Demuxer (HPD) [3] should be worth a look
if you are dealing with packetized variable length data.
Hope those pointer can get you started. If you have further questions

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
10 matches
