[Discuss-gnuradio] gnuradio-core missing / UCLA Zigbee PHY in gnuradio version 3.6.5.1

[Jaeho]

Hello

i am using gnuradio version 3.6.5.1. i download it using wget command line.

$ wget http://www.sbrac.org/files/build-gnuradio
$ chmod a+x ./build-gnuradio
$ ./build-gnuradio -o (i used -o option to get 3.6.5.1 version)

i find the old UCLA Zigbee PHY from https://github.com/UpYou/gr-ieee802-15-4

so i download it and try to build using following method
$ ./bootstrap
$ ./configure
$ make
$ make check

But in make step, i have an error as below, so i couldn't complete build.
=========================================================================================
checking for gnuradio-core >= 2... Package gnuradio-core was not found in
the pkg-config search path. Perhaps you should add the directory containing
`gnuradio-core.pc' to the PKG_CONFIG_PATH environment variable No package
'gnuradio-core' found
configure: error: Library requirements (gnuradio-core >= 2) not met;
consider adjusting the PKG_CONFIG_PATH environment variable if your
libraries are in a nonstandard prefix so pkg-config can find them.
=========================================================================================

how can i fix it? why gnuradio-core is missing in gnuradio 3.6.5.1?
i checked gnuradio 3.6.5.1.tar.gz include gnuradio-core folder
but there's no gnuradio-core in mine. why? what's wrong with me?

Additionally, the reason why i used wget command is i have an error also
build from source cause of gnuradio-core.
it also is occured because of gnuradio-core missing.
how can i fix this problem about gnuradio-core?

Hi,

if it's fine for you to use a more recent version of GNU Radio, you
could give this repo a try

https://github.com/bastibl/gr-ieee802-15-4

[Jaeho]

Thank you for your advice.

Actually, i already download that before, but i have a problem.

I used ieee802_15_4_pkt.ieee802_15_4_mod_pkts() function in UCLA Zigbee PHY
where is in gnuradio.ucla_blks

i want replace this function to new function in new version that you
recommend, but i can't find replacement.

If you know the replacement of gnuradio.ulca_blks and gnuradio.ucla, please
let me know.

God Bless you,
Jaeho

I don't get your question, but this version uses GNU Radio blocks for
modulation. So if you want to change something with regard to
modulation, just change the flow graph.

Best,
Bastian

[Jaeho]

<Loading Image...>
<Loading Image...>

for help describe my question, i insert images.

this code is used before, and i changed gnuradio version to 3.7

so i could not use "from gnuradio.ucla_blks import ieee802_15_4_pkt" module.

and also i could not use "ieee802_15_4_pkt.ieee802_15_4_mod_pkts()"
function.

but i want to use this source code just modify this function to new function
in "gr-ieee802-15-4" that you recommend.

The problem is which could be the replacement of above function in
"gr-ieee802-15-4"

Thank you,
Jaeho

To see how the code is imported / used just open the flow graphs in GNU
Radio Companion, compile them and look at the produced python file.

[Jaeho]

I am sorry. I think my problem description was not good enough make you
understand.

so I changed my question.

actually, my source code, did not generated by GNU Radio Companion. code
writer just programmed in script as python code at the beginning.

it means i have no grc file to open GNU Radio Companion and i already have
python file.

So my question is,

1. how can i use gr-ieee802-15-4 from
https://github.com/bastibl/gr-ieee802-15-4?

2. how can i find proper function in gr-ieee802-15-4 module to replace my
old source code function (from UCLA Zigbee PHY) such as
ieee802_15_4_pkt.ieee802_15_4_mod_pkt()?

: To make question more specific, below is my question

ieee802_15_4_pkt.ieee802_15_4_mod_pkt() ->
????
from UCLA Zigbee PHY
from gr-ieee802-15-4

As I said, the modulation was changed to utilize GNU Radio blocks
instead of reproducing functionality in the module. In addition, the
code does not use old message queues, but was ported to the new message
passing system.
This means it won't be a search-replace update of the old code, so there
is no answer to your question.

But:
ieee802_15_4_mod_pkt() was a hierarchical block for modulation. Also the
current code uses a hierarchical block, but generates it from a GRC flow
graph.
So again, if I were you, I would just generate the new hierarchical
block for modulation (ieee802_15_4_OQPSK_PHY.grc) and a flow graph that
uses it (transceiver_OQPSK.grc). This will provide you all code snippets
you need to update your hand-coded python scripts.

Best,
Bastian

[Jaeho]

I am sorry for my question

I got your advice, and i tried to refer codes(ieee802_15_4_oqpsk_phy.py and
transceiver_oqpsk.py) that are generated from ieee802_15_4_OQPSK_PHY.grc and
transceiver_OQPSK.grc.

BUT!! VERY UNFORTUNATELY, i could not realize how can i modify my old codes.

There's no code for modulation ( the thing that i need to replace my
function )
(or maybe i could not find although code are existed in gr-ieee802_15_4)

I am very sorry for ask you with my code, but can you help me modify my code
included in below?
Below class code is my old source code that using old UCLA Zigbee PHY
module.
And i hope modify this code with gr-ieee802-15-4 (new version of UCLA Zigbee
PHY)

How can i modify this code with new library?

or if you have more helpful manual or source code, can you send me those to
my email address?

My email address is ***@gmail.com

Please help me to solve my problem....

God Bless You,

Jaeho,

ieee802_15_4_oqpsk_phy *contains* the whole modulator/packetizer.
With all the comments in the GRC, I think it's pretty clear which parts
do what. You will simply need to integrate that same structure instead
of the old _mod_pkt block; you can either do that by simply using the
hier block that is contained in

ieee802_15_4_oqpsk_phy.py

or you can simply just use the same blocks as the GRC in your applications.
So: ieee802_15_4_oqpsk_phy is simply a block. Use it. It's not hard. If
you have continued problems with using hier blocks, I recommend going
through the guided tutorials 2 & 3:
https://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorials

It has two inputs, rx_in and tx_in, and two outputs, rx_out and tx_out,
as you can see from the GRC. Connecting the USRP sink to the tx_out and
whatever gives you the data you want to transmit to tx_in should do the
trick.

Post by Jaeho
or if you have more helpful manual or source code, can you send me those to
my email address?

Um, I don't know how to put this, so I'll be blunt:
The source code and architecture of gr-ieee802-15-4 are pretty clear,
and the GRC files we're looking at here are especially well-commented;
I'm afraid you will need to just try and use it a little more, and the
problems you're having understanding how to use ieee802_15_4_oqpsk_phy
might really point to you needing a little more experience working with
hierarchical blocks, which is an aspect very central for GNU Radio
development.

I'm very optimistic you will manage to build something amazing! Have a
look at transceiver_OQPSK.grc, it uses ieee802_15_4_oqpsk_phy.

Best regards,
Marcus

i am sorry, i have more question about your advice.

1. i opened ieee802_15_4_OQPSK_PHY.grc and transceiver_OQPSK.grc.
<Loading Image...>

like this images, there are some missing blocks. i guessed these blocks came
from gr-foo.
But i installed gr-foo following install instruction in git main page and
there were no error messages during install processing.
please give me advice what can i do? what is the problem of this situation?

2. Actually, i generated python files (ieee802_15_4_oqpsk_phy.py and
transceiver_oqpsk.py) from .grc files, using F5(hot key), although there are
some error. But i could not find any hints from these python code to replace
my old code, which is /*self.packet_transmitter =

Can you give me some more hints or advice to solve it?

Dear Jaeho,

It seems that you didn't install gr-ieee802_15_4 yet.

In IEEE802.15.4 category, there is no blocks at all.
CSS PHY and OQPSK PHY blocks are just generated after you build flow graphs
which are configure as hierarchy blocks.

Back to the original post of this thread, in short,
Run commands:

./bootstrap
./configure
make
[sudo] make install
[sudo] ldconfig

(Assuming you have the proper version of GNU Radio, gr-ieee802_15_4)

Regards,
Jeon.

Thank you for your advice.

but i think, your advice is for about old version gr-ieee802_15_4 which name
was UCLA Zigbee PHY.

it supported only until gnuradio version 3.5, and i am now using gnuradio
version 3.7.

so i downloaded new version of gr-ieee802_15_4, it's way to install is as
below

git clone git://github.com/bastibl/gr-ieee802-15-4.git
cd gr-ieee802-15-4
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

so i already run it, and installed with any error message.

so, i hope ask one more, same question with additional question.

the figure that i insert as below, some files has comment that "compile on
mac"

is this comments mean that those file works on only Apple Mac? or mean MAC
layer?

No, it's not the old one.

If you installed gr-ieee802-15-4 successfully, with the commands following:

git clone https://github.com/bastibl/gr-ieee802-15-4
cd gr-ieee802-15-4
mkdir build
cd build
cmake ..
make
[sudo] make install
[sudo] ldconfig

you should be able to see lots of blocks in IEEE802.15.4 category:



But in your case, you have only two blocks which are generated from
hierarchy blocks.
Which are not present in my case since I didn't build hierarchy block, yet.

So, my suggestion is, double check whether intallation is successful or not.

Regards,
Jeon.

Hi,

looks like GRC cannot find your blocks, so I guess you should adapt your
local_blocks_path

No, it just means that it also compiles on OS X.

[Jaeho]

Thank you for your advice, because of your advice, i install gnuradio and
companion properly.

But the problem is still remained, i could not realize how can i modify my
old code with flow graph.

I already saw your recommended codes, ieee802_15_4_oqpsk_phy.grc,
transceiver_OQPSK.grc and .py files.

But i don't understand how can i use these code to modify my code that i
uploaded previous thread.

I also see tutorials that you recommend, but there is not enough information
for me.

Can you give me more hints or advices to modify old code?

Thanks
Jaeho

I cannot give you any other advice then look at the generated py-files
and adapt you code accordingly.

I guess I could help you better if you would come up with a more
specific question...

Best,
Bastian
