Hi, I was wondering if there is some way to destroy the instance of a sink/source in python.

rx = limesdr.source(arg1, arg2, arg3, arg4)
del rx

does'nt work.

The new gr-3.8 fails to compile for me.

Compilation output:
https://pastebin.com/9c94ivdg

System:
archlinux x86_64
python 3.8.1
python2 2.7.17
swig 4.0.1
limesuite 20.01.0
gnuradio 3.8.0 (actually 3.8.0.0 due to archlinux packaging mistake)

Can you recommend a specific commit version of gnuradio that this was tried and tested with?

It seems that the limesdr block limited max gain to 60dB:

However, when I was using SDRangel to output some NFM signals, it seems it can go to 70dB.

I can also confirm that setting 70dB in SDRangel had higher power output than 60dB in GNURadio.

What is the actual maximum gain for Tx?

Just installed the MacPort and that went well. I'm working from the example FM receiver with changes to the gui for QT. Now I'm seeing the following at compile time

This is clearly not what is show in the documentation tab:
limesdr_source make(std::string serial, int channel_mode, std::string const & filename) -> source_sptr Return a shared_ptr to a new instance of source. To avoid accidental use of raw pointers, source's constructor is private. limesdr::source::make is the public interface for creating new instances. Params: (serial, channel_mode, filename)

I suspect that I may have some detritus left over from previous installs with the brew package manager? Could this be a version 1 vs 2 issue?

It would be great if there is parameter on sink and/or source block to manually (or semiautomatically) control VCTCXO DAC parameter from GNU radio by user.

PS: I am no programmer, but will try to add this as personal exercise and play with code.

I already downloaded and install gr-lte for gnuradio on ubuntu 16, and i take a look at the example but i don't see nothing about interfacing with an SDR source. Can you help me to catch LTE stream from air with LimeSDR board?

Freq slider has no effect.

It is no longer possible to use gr-limesdr blocks in GRC or python.

System is Ubuntu 16.04 LTS, GR is compiled with Python3.5.

Getting this error for some reason, I only just updated the repo and redid the cmake.

Any clues as too what might be happening?

Ubuntu 16.04, GRC 3.7.10.1-62

See:

https://discourse.myriadrf.org/t/limesdr-usb-inconsistent-configuration-and-sample-rate/6345/3

Perhaps we could grey out all the other settings when an INI file is loaded?

There are some writes to FPGA regs in mini_switch_workaround and set_lna_path_mini - what are those writes for, are they necessary to make the lime mini work? Why is that stuff not part of Limesuite?

Hi,
in your sourcecode "lib/common/device_handler.cc", there is

506 | if (nco_freq > 0)
507 | cmix_mode = 0;
508 | else if (nco_freq < 0)
509 | cmix_mode = 1;

But with my test, it seems be reversed? Are you sure it's correct in your code?

I get

Hi there,

trying to capture wifi packets with gr-ieee802-11 and my LimeSDR-Mini. I am asked for a Calibration Bandwidth and analog filter bandwidth however these terms aren't referenced anywhere that I can see.

Has anyone attempted to do something similar?

Thanks

pmt is a required component, its exposed in the headers/API and needed by the swig compile

hello , I ran examples, fm_receiver. I can see a impulse in the graph. But there seems to be some noisy instead of the fm sound. Does anybody help to find the problem? Thanks

Line 73, should be

LimeUtil --find

I.e. no space after the dashes. Not set up to do a PR at the moment.

Can it worked on GNU 3.7.3
(Windows-32bit)?
When I extract the limesdr zip you can see errors like:
element block content does not follow DTD.
no declaration for element
Can I use limesdr mini and gnu on win32?

Hi, cmake reports
GnuRadio version required: >="3.7.8" < "3.8.0" found: "3.8.0.0"
Is there any way to force compiling or i have to wait for a new version to be released ?

Neither block, source nor sink, is registered as a throttle block. Therefore, the following warning is issued when generating the python code and no other throttle block is used in the flow graph.

>>> Warning: This flow graph may not have flow control: no audio or RF hardware blocks found. Add a Misc->Throttle block to your flow graph to avoid CPU congestion.

There will be a lot of changes necessary to support GNU-Radio 3.8, currently it is still in development. Documentation to port to 3.8 is provided here.

Right now it doesn't compile(#37) and the block description needs to be changed to yaml(#27).
At minimum, things that will need to be updated/changed are: CMake, python?, xml to yaml, examples.

this compiles on macOS Mojave 10.14.13 and gnuradio installed via Macports, but does not show up under grc

the make installpart seems to need adaptation as files go to /usr/local

any suggestions?

thanks in advance

Michael

When config file is loaded it is not possible to change TX frequency.
config file is generated with LimeSuiteGUI. Config file is nacessary because running GRC without config, TX calibration is performed and calibration fail.

Hey, could you add a release so that will be easier to distribute this software?

Thanks

Hi all,

I am currently getting into Software Defined Radio using the LimeSDR USB Board with GNU Radio. For a research project, I want to be able to transmit a signal over one antenna at around 2.4GHz and receive it over two different antennas (best case: on the same board / okay case: on another board).
I've created a simple flow graph, receiving a transmitted signal over either channel A or B and feeding it into a Time Sink block - which, from my perspective, works as expected. But as soon, as I want to use a LimeSuite Source working on both channels (A+B)MIMO, no signal is received at both channels.

• Do I additionally have to tell the board or the flow graph that it is used in MIMO mode now, except changing the LimeSuite Source's channel to (A+B)MIMO?

• I know that my usecase is rather SIMO than MIMO, but this shouldn't affect the receiver side, should it?

• Is receiving on two antennas on channels A and B even possible with the LimeSuite Source or do I basically misunderstand the concept of "channels"?

Thank you in advance!

How to deal with it??

Hello,

I seem to be experiencing an issue (on two different hosts/archirectures, using two different LimeSDR USBs) where if the sample rate is set to 2.5e6 or lower then no samples are returned. This was experienced with any use of the LimeSDR RX block with sample rate <=2.5e6. Even some of the example flowgraphs (for example, FM_receiver.grc) do not work because the example sample rates are only 2M by default. However, if the sample rate is set to anything greater than 2.5M (such as 2.51e6) then suddenly samples begin to flow and everything works fine.

Software versions in use:
LimeSuiteGUI 19.01.0 (commit 7557e29)
gr-limesdr 2.0.1 (commit 4125e1f)

Output from flowgraph when it does not work:

Will there be a release for GnuRadio 3.8.1.0. in the next time? Or is there any other way to compile it for GnuRadio 3.8.1.0 ?

I see that there is a function called “disable_DC_corrections” in device_handler.cc; however, that is not implemented in the python wrapper for the “sink” object. It would help me immensely if that is added.

I’m not requesting that be added to the block in GRC (that would be cool though). I can manually add the command in the GRC generated python code, so hopefully this doesn’t require a lot of work!

Tx Block(Sink) does not support sample rate above the 2MHz

Hello,

I've tried testing the gr-limesdr plugin, have all the required utilities but for some reason it throws a Python error when using the FM_receiver.grc example.

I'm using GNU Radio Companion 3.7.11 on Ubuntu 18.04 with Python 2.7.15rc1. Do you know what could cause this? It doesn't seem like an issue with hardware or GNU Radio but maybe a version mismatch? Maybe the one I have expects blocks to follow a different API.

I have created a new module in gnuradio-companion(GRC), the new project is called zzz and adds the module stoo which has been compiled successfully and can generate view modules in GRC.
But when running a simple program including this new mod named stoo in GRC, the error is as follows, I Online access said that the pyc file is asked, but the error path points to the stoloc.py file. This is a python file that is automatically generated by a program running in GRC.
Sincerely ask for help ! Thanks!

Sink exit should disable the transmitter.

Hi all,

I have already reported this on MyriadRF discourse, but maybe this is more official way, so just in case I will repeat it here as well.

I have tested gr-limesdr in full MIMO configuration (transmitting BPSK signals at two different frequencies with both TX channels and receiving them at the same time at the same frequencies with both RX channels) and found some obvious bugs in NCO offsets implementation.

I’ve been using sample rate of 6 MHz, center frequency of 2.44 GHz, NCO offsets of -2MHz and +2MHz for channels 0 and 1, respectively. Expected signal is shown in a picture below:

However, with spectrum analyzer I saw only signal from TX channel 1 actually present over-the-air, and none of the signals was correctly received.

All this works just fine with UHD and Osmocom blocks, so this is obviously gr-limesdr issue.

When generating a flow graph within GRC, if CH0 is set to "B" in SISO mode, the generated code has "0" (Channel 0, or A) hard coded into all callback functions. This prevents any GRC generated code from modifying Channel B parameters while the flow graph is running. Manual editing of the code is required

Example to reproduce:
Using the signal_generator.grc example flow graph from gr-limesdr, change CH0 to "B" and attempt to run and adjust any channel specific parameters while running (TX Gain for example).

I'm trying to get the FM TX example working, but I get this error message:

I know it has something to do with older versions, I also installed the package into /usr/local/ but it didn't help.

I'm trying to build gr-limesdr on OSX after upgrading to Mojave and Xcode 10.1 (10B61), then removing all homebrew and port installs then reinstalling GNURadio from scratch with MacPorts to clean-up tons of conflicts I'd built-up. I've done the usual git, mkdir build, cmake .. two-step but was receiving an error from cmake:

After reviewing the port boost version:

After seeing that the boost version is "@1.66.0_3 (devel)", I edited the cmake file at line 64 to read (note the addition of "1.66.0_3" that matches what my version of boot reported):

set(Boost_ADDITIONAL_VERSIONS "1.35.0" "1.35" "1.36.0" "1.36" "1.37.0" "1.37" "1.38.0" "1.38" "1.39.0" "1.39" "1.40.0" "1.40" "1.41.0" "1.41" "1.42.0" "1.42" "1.43.0" "1.43" "1.44.0" "1.44" "1.45.0" "1.45" "1.46.0" "1.46" "1.47.0" "1.47" "1.48.0" "1.48" "1.49.0" "1.49" "1.50.0" "1.50" "1.51.0" "1.51" "1.52.0" "1.52" "1.53.0" "1.53" "1.54.0" "1.54" "1.55.0" "1.55" "1.56.0" "1.56" "1.57.0" "1.57" "1.58.0" "1.58" "1.59.0" "1.59" "1.60.0" "1.60" "1.61.0" "1.61" "1.62.0" "1.62" "1.63.0" "1.63" "1.64.0" "1.64" "1.65.0" "1.65" "1.66.0" "1.66" "1.67.0" "1.67" "1.68.0" "1.68" "1.69.0" "1.69" "1.66.0_3" )

Not sure best practices for cmake, etc. Am I supposed to force the latest version in port, tell cmake to just live with my version, etc? Will I regret building from a dev boost, what's the best way to handle this type of issue, etc? Mostly putting this here as a note in a bottle for the next person. I did see similar issues on my Linux box. Regardless of my likely self-inflicted install wounds, I'm really enjoying LimeSDR and the new driver, thanks team. (PS would greatly value control of GPIOs)
-scott

Toggling the AGC would seem like a popular setting and suggest we add a checkbox for this.

we have this repo
we have the Soapy driver as outlined here: https://discourse.myriadrf.org/t/guide-gnuradio-and-gqrx-with-limesdr-mini-on-macos-10-13/2702

which one is preferrable? why?

thanks in advance

Michael

Wondering if there are any debian packages to install gr-limesdr. I can compile from source, but prefer to use to package for automated installation.

I already have GNU Radio installed using apt install gnuradio
