Hello @Maryam, |

Hi,
Thank you for your email, I sent the explanation on my email, this is
whatever I receive :
xxxx.....MacBook-Pro gr-lora_sdr % python3 -c "from gnuradio import
lora_sdr"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: cannot import name 'lora_sdr' from 'gnuradio'
(/opt/homebrew/lib/python3.12/site-packages/gnuradio/__init__.py)

Hello @Maryam <https://github.com/Maryam>,
I've never tried the installation from source on Mac. If the block don't
appear but you managed to build and install the oot module without errors,
I would suspect an issue with the installation path. How did you install
gnuradio? When installing this OOT module, what was installation path? If
you open a terminal, run python and try to ''import lora_sdr'' does it find
the module?

*Another question: *I was disappointed to install on Mac so I installed the
LoRa blocks from gr-Lora-sdr Github on the Ubuntu arm based VM.
I am really thankful if you could clarify for me:
How can I install a Heltec LoRa32 (863~928) as a LoRa transmitter node to
send data and check the log file on the receiver side (my receiver is an
USRP) by GNU radio?

Maryam

Ok for the installation, there is an error for the installation path (I'm really not familiar with mac so I'll try my best). For your other question: |

Thank you for your support first,
I did whatever you sent, the LoRa blocks appeared in GNU radio but, when I
open a lora_TX.grc example in GNU radio I will receive this error there :
Error:
mapping values are not allowed in this context
in "/Users/maryamf/Downloads/lora_TX.grc", line 208, column 97
>> Failure
Could you please explain to me more about using " sx1262" ? I am not
familiar with it.
Actually I would implement a LoRa environment by using SDR and GNU radio
and Heltec LoRa board, I am looking for a good scenario to send and receive
data and check the log file of received data. Then I wanna start a jamming
scenario toward that and test the result.
Are you familiar with that library you sent?

Based on the error messages I would try to install the module where python
looks for it, can you try to install the OOT module in /opt/homebrew/ by
running
cmake .. -DCMAKE_INSTALL_PREFIX=/opt/homebrew
make install (you may need to use "sudo make install" to have the right
to install things there).
For your other question:
I don't have that exact board available, but I could use sx1262 without
issues. You need to get a library that allow you to configure the LoRa chip
and send messages, then set the same configuration (spreading factor,
center frequency, bandwidth,sync word,..) for the USRP (in gnuradio) and
for your node. I can't test it, but this
<https://github.com/HelTecAutomation/Heltec_ESP32/tree/master> and look
at the loraBasic examples should do the trick.

There should be a format error that only appears on mac.. can you try copy and past the content of the file in https://www.yamllint.com/ and see if it finds any error? Unfortunately, I can't give you a full tutorial. The link is the reference code from Heltec. You should be able to find some tutorial for your specific board. |

Many thanks.
I did copy and paste the content of the file in https://www.yamllint.com/,
and received : Valid YAML!

- Generate a random flowgraph and try to see what seems different
between the .grc file generated and the one in the example.
- Reproduce the Tx flowgraph from scratch, following the template
shown below (you can use the hierachical block to make it easier, at least
to try it out).

Hi,
I downloaded lora-RX flowgraph. It works on Ubuntu, one question I have is,
how can I see the chirps? I must add which block and where inside the
flowgraph?
Sincerely,
Maryam

Hello, |

Hello,
I need to log the physical layer raw data (bits), I would use file sink
block and add in the proper output in the GNUradio flow graph, it must
connect to the output of Header decoder, gray mapping, fft demod, or what?
Sincerely,
Maryam

Hello,
you can see them by using a "QT GUI Waterfall". However this block has a
relatively low resolution so you will be able to see the chirps clearly
only for large SFs (e.g. sf12). You might want to decrease the update
period as well.
Else you can just save the IQ samples to a file and load them with any
programing language you like and plot the instantaneous frequency with some
form of differential(unwrap(angle(IQ_samples))).

Hi,
I followed step by step the installation part and install gr-lora-sdr module (without condo), when I check I see lora_sdr_puthon.so, and saw the lora blocks inside GNURadio but when I open an example from your repository it does not work! I trouble shout several times but it still does not work, last time all lora blocks disappeared from GNURadio!
Could you help me to install on Mac?
