Hi,

if I hit the play button in sdr# I only get the message "unable to create buffer" . I'm able to connect to the device in the settings of your plugin and I've changed the sampling rate too.

I'm using the latest sdr#, latest pluto firmware and the latest of your plugin.

BTW I've flashed the plutoweb image on it.

Cheers
Norbert

All was running well with SDRsharp and my Pluto . but was obliged to use 3MS rate (4MS gave me glitches, impossible to use it). FM broadcast was received very well and with a good sound

I have update to v0.27 firmware:
=> now there is an issue if we use the "Slow attack AGC" ==> we get a message "unable to write channel attribute -95"
If I do not select this option, all seems to run well.

I will go back to firmware 0.26 and I have no more the "Slow attack AGC" issue.

thank you for this good work.

Hello,

i use the sdr# v.1.0.0.1777 (tried both official and community editions) on windows 10 x64 and i have trouble using plutosdr plugin (windows binaries).
First of all, the frontends.xml is missing. Should I create it manually?
I tried to insert xml entry into plugins.xml, but plutosdr doesn't appears in sources list.

there is an other SDR software, where the PlutoSDR has much more functions available as on the plugin here. maybe you can pick some options from there and put it to your plugin...

PlutoSDR input plugin (SDRangel)

e.g.:

• offset tuning,
• ppm correction,
• hardware FIR,
• hardware Decimation,
• different auto gain modes,
• ...

This frontend somehow prevents that you can select the frequencies in the Frequency Manager with a double-click. This works with other frontends. SDRsharp version 1.0.0.1666 x86.

... doesn't work at the moment. I don't know why.

use "ip:192.168.2.1" for now.

There is a plugin for SDR# that connects via DDE to a satellite tracking program like SatPC32 or WXtrack so the frequency information of the tracking program is sent to SDR# and then the frequency is changed in the SDR device via SDR#. Currently the frequency of PlutoSDR does not change as expected. Is there perhaps a simple change that you might make in the PlutoSDR to allow the frequency to change via the plugin? The SDR# plugin, current is V8, including the source code used is here: http://www.satsignal.eu/software/DDETracker.html

It seems that the ad9361-phy,xo_correction attribute isn't used to correctly tune the RX LO, the frequency always seems to be out by a couple hundred Hz...

Might also be only a badly configured XO correction value on my PlutoSDR, but I don't have a stable reference clock source at hand ):

I have SDRSharp running through Mono on the new Ubuntu release but I cannot locate any XML files to update. I am unsure of what is different between the Linux and Windows installation. I am fairly new to Linux, Xamarin/Mono, and SDRSharp. Is there an easy solution for this?

-edit: The linux version on github is out of date and does not have any XML files, says its version 0.0.0.0. I will need to get a newer version going here that includes an xml to edit.

Thanks for the effort in producing a plugin for SDR#
Starting the receiver provide me with the error in the title.
Any ideas?

I am using the latest version of SDR# (x86) sand copied the libiio dlls in the SDR# directory

Please your help !

Borislav,

I was looking at compiling the plugin to work under to normal expected frequency range to no avail. Perhaps I'm doing it wrong but it looks like I'm missing references that were not provided in the source.

Once I had it working on the original range I had intended to make it selectable with a dropdown box.

Version 0.4.3 displays 0.4.2 in the dialog.

I get an exception when trying to change the gain. Looks like there's something wrong with the communication with the Pluto device.

I tested with iio_info and that seems to work (I get a list of attributes) also the iio oscilloscope is working.
libiio-Version: v0.17

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Hi,

I cannot build the plugin. What I did:

Build sdrsharp from here https://github.com/cgommel/sdrsharp

xbuild /p:TargetFrameworkVersion="v4.5" /p:Configuration=Release

then cloned sdrsharp-plutosdr, linked the two dlls Radio, Common and started buiilding

xbuild /p:TargetFrameworkVersion="v4.5" /p:Configuration=Release

Result
`

I cannot find IIQStreamController in sdrsharp. I think I am missing something....

Apparently SDR# developers changed how they reference plugin relatively to the main SDR# folder.
File FrontEnds.xml is not there anymore, and its presence appears irrelevant.
SDRSharp.config file has an explicit entry key="core.pluginsDirectory"
There is a Plugins.xml file with a test entry.

If I place sdrsharp-plutosdr files in the "Plugins" subfolder and edit the plugins.xml file adding the line
add key="PlutoSDR" value="SDRSharp.PlutoSDR.PlutoSDRIO,SDRSharp.PlutoSDR"
when i run SDR# a "PluginError.log" is created with the following content.

*** Plugin Load Error - 2022-01-02 11:45:46.754

Any Suggestions?

when i double-click to a stored frequency of the "Frequency Manager" the PlutoSDR does not tune to the selected frequency, does not set the bandwidth and does not change the mode of demodulation.

it is not an issue when i use RTL-SDR (USB).

i used
sdr-sharp rev 1666,
your sdrsharp-plutosdr plugin version 0.4.3 beta (shown as 0.4.2 on the plugin dialog itself),
PlutoSDR has 70-6000MHz hack is applied and the firmware version is v0.28.

Hi the Meteor 2 qpsk demodulator is not working with the pluto driver.

Normally when you enable the demodulator it mutes the souud this doesn't happen with the pluto front end, tcp service shows as started but in reality the port is not opened and the imaging software cant see anything to connect to.

It looks like the iq stream is hardcoded to the audio bus and not routable internally to the demodulator.

tested on several versions of sdr# and qpsk demod plugin, fresh install of win10 sdr# and qpsk plugin, all exhibit same behaviour, demod is not routed, swap the frontend to rtl-sdr, airspy, iq file, demod runs no prob on all instances.

as a side note, soem access to the 3 basic filter parameters would be nice: enable/disable, auto on/off, load of iio ossiloscope filter file, currently im loading both sdrsharp and iio-oscilloscope, with oscilloscope open i am able to communicate with the back end and configure the filters while sdr# is running but the moment you stop and start sdr# you need to reload the filter file from oscilloscope as the pluto disconect / reconnect in sdr# forces the default boot config to be reloaded which is filter off, if this was part of the saved config of the front end it would be a big bonus to using the pluto as a standard sdr, also a switch to disable the auto tx on 2.4ghz would be great even if it just max attenuates.

Thank you for providing a way to use the Pluto with SDR#. It was ugly and dirty, but I got it to work. Here are some things to consider.

Your Filenames are not distinguishable once they are inside the SDR# installation folder. Could you prefix them so they are clearly all Pluto files? For instance:

SDRSharp.PlutoSDR.dll - this follows their conventions and you had to name it this. But it could be named anything, if you change the FrontEnds.xml instructions

I was confused because the SDRSharp.PlutoSDR.PlutoSDRIO is not a file, but the driver that has to be installed separately?

Here is where I would start:

SDRSharp.PlutoSDR.dll --> PlutoSDR.SDRSharp.dll
libad9361.dll --> PlutoSDR.libad9361.dll
libiio.dll --> PlutoSDR.libiio.dll
libiio-sharp.dll --> PlutoSDR.libiio-sharp.dll
libserialport-0.dll --> PlutoSDR.libserialport-0.dll
libusb-1.0.dll --> PlutoSDR.libusb-1.0.dll
libxml2.dll --> PlutoSDR.libxml2.dll
msvcr120.dll --> PlutoSDR.msvcr120.dll

Everyone is duplicating certain functions. I cannot tell if they are true duplicates or just all using the same libusb functions.

I have RTL_SDR V3s, AirSpy Discovery, generic RTL_SDR, Nooelec E4000, Adalm-Pluto. I expect I will have more. I like SDR# to view the receiver. The gains are ALL different. The filters are ALL different.

I am using rtl_power on the RTL devices to scan their entire frequency range. And probably will use rx_power, the Soapy version, to cover Pluto and AirSpy and others.

I am trying to develop a complete map of the global electromagnetic field. Particularly, from microHz to TeraHz. That means using a whole range of devices. Having standards will allow individual devices to be calibrated. I am buying pairs to check manufacturing variation.

I have to have all the sensors individually calibrated, and to be able to compare pairs or any number of sensors with each other, and to compare the whole of the SDR network with the magnetometer, radio astronomy and other electromagnetic arrays. I will provide an index and a database soon, so people can see what I find. If you are interested in this sort of thing, I am happy to explain further.

The instructions on setting up a Pluto are bad, all the way from Analog.com to you. There are too many out of date and fragmentary pieces by too many authors.

The Soapy also has a way to handle dlls required by different SDR software. They are doing an OK job, but everyone is going in different directions, on different sites, with different quality and approach to instructions and names.

Richard Collins, The Internet Foundation

It seems like Zoom FFT and Audio Noise Reduction plugin's among others do not work with the PlutoSDR but work with an RTL-SDR.

Currently only works with 32bit!

Hello,
I got my Pluto several days ago and tried to extend the frequency range as described on the site https://wiki.analog.com/university/tools/pluto/users/customizing in the Updating to the AD9364 section.
The error message „Unsupported LO frequency“ is prompted If I tune to the lower or higher frequency. All further frequency changes (also in official Pluto range) do not work before SDR# will not be restarted.
Do you have an idea what can be wrong?

Can I set the IP address of the network connected Pluto+ ?
Or is this only working via a usb connected (local) Adalm Pluto or Pluto+ ?

Thanks for any suggestions to solve.
