add ADALM PLUTO in the list of supported devices

[DG9BFC]

i am sure a clever programmer can add the adalm pluto to the list of supported devices ... but sadly i am not a clever programmer :-( the needed driver files are open so it should not be that difficult to add this sdr in the list so ... please ... can you add the pluto in the list and add the needed drivers to the installer?!? thank you sooooo much dg9bfc sigi

[JvanKatwijk]

well, if you send me (a link to) the API of the device I'll give it a try. But I cannot test the result

You could try to use a fifo.

mkfifo stdin.raw

Then stream a 8 bit unsigned signal from your device to this fifo. In Qt-DAB just open this fifo.

[JvanKatwijk]

... and furthermore, there is an soapy interface driver for the pluto Nevertheless, if the API is more or less similar to one of the devices already supported, it would be an interesting experience to create one

https://wiki.analog.com/university/tools/pluto/users here you should find further info and some links should be easy for a programmer to find the needed packages greetz sigi dg9bfc

[DG9BFC]

and from here: https://wiki.analog.com/university/tools/pluto/controlling_the_transceiver_and_transferring_data .....

PlutoSDR runs Linux. The device drivers allowing you to control the transceiver and capture samples are therefore part of to the Linux Industrial IO (IIO) framework. IIO is a kernel subsystem for analog to digital or digital to analog converters and related hardware. IIO communicates with user space via sysfs and a character devices. From a plain user interaction point of view this is quite intuitive, since everything is just a file. However when controlling the device from software, this can be quite painful, since you simple want to call a function or method, instead of doing string manipulation and file IO. LibIIO fills this gap, provides all sorts of device abstraction and handles all kind of IIO internals. LibIIO is cross platform and also provides different language bindings, so that you can control IIO devices from C, C++, C# or Python.

....... hope that helps a bit and ... if you not already own a pluto ... GO AND GET ONE :-)

[andimik]

According to this link a PlutoSDR cannot receive DAB+ out of the box.

https://shop.funk24.net/media/pdf/e8/9d/18/plutosdr.pdf

https://wiki.analog.com/university/tools/pluto/users/intro

Receive (labeled 'Rx') 300 MHz - 3.8 GHz

Seems a hack is necessary:

https://www.rtl-sdr.com/adalm-pluto-sdr-hack-tune-70-mhz-to-6-ghz-and-gqrx-install/ https://wiki.analog.com/university/tools/pluto/users/customizing

@DG9BFC Can you confirm you can receive VHF III Band (177 MHz - 230 MHz)?

[DG9BFC]

yes ... definitely ... also on fm band ... with the hack it works 70 to 6000 even lower ... if you set local to 70 and use max sampling speed you can go down to 40 mhz ... so dab on vhf should be easy

[DG9BFC]

fw_setenv attr_name compatible

fw_setenv attr_val ad9364

fw_setenv maxcpus

pluto_reboot reset

every pluto owner knows (or should know) these 4 lines ...

[andimik]

Can you set the sampling rate to 2,048 MS or 4,096 Ms?

[JvanKatwijk]

For creating interface code to qt-dab one needs a. open the device b. set the samplerate to 2048000 and a bandwidth of app 1.5 MHz c. ability to set and change frequency and gain settings d. read data

I saw example code to open the device, set the samplerate, bandwidth to large values No clue how to change a frequency setting or a gain setting though

Wrt buying one: what would be the advantage over the hackrf, limeSDR for higher frequencies and over airspy and sdrplay RSP for "just" the frequencies to 2 GHz? I did not see any

[andimik]

Me too.

A receiver which can receive FM and DAB only after a hack is really questionable.

I don't see any advantage to my Airspy and HackRF.

[DG9BFC]

a man can not have enough sdr to try :-) the bandwidth hack is well known and all pluto owners do that ... its not questionable ... it is stable and reliable ... and you only have to do that once ... the setting is permanent (no need to do the hack on every start) advantage against hack rf?? hack rf is only 8 bits simplex while pluto is 12 bit fullduplex the pluto is a good sdr for the higher bands ....goes up to 6 gig! with the spectrum analyzer and tracking generator software you can tune antennas or filters (say you wanna build a bandpass filter for the dab band) ... only possible with a fullduplex sdr ... ok ... for only receive dab ... a 10 bucks rtl dongle will do the job fine ... thats not the point here ... any sdr can be used for that ... the point is the pluto has lots of pros (also for other things and NOT only dab receive) ...

[andimik]

Sorry, but I still can't see any advantage.

Could you please answer Jan's and my question? Can you set it to the needed sampling rate and bandwidth?

[DG9BFC]

yes you can ... 500kc ... 1 meg 2 meg ...whatever you need (as far as i know up to 6 mhz bw but i never used that bw cause my pc is tooo slow for that) max sampling is 60 megs (after the hack was made) but you can not squeeze that much data over usb2 (so you then need to do decimation and use only say 1.5 or 2 megs bw) gain setting can be set to manual (-10 to +73 db gain) or to auto (slow attack, hybrid, fast attack)

[JvanKatwijk]

I believe you can, but so far I did not find a description of the "how". As said, there is a fragment of code - dated 2017 - that - by means of example - tells how to set up the device, set an initial freq, bandwidth and samplerate, and shows how to extract the data. But I need some info on what to do when changing a frequency - e.g. do I stop processing completely and restart with a new frequency - and gain.

For the other devices, I have always found a - more or less complete - functional description of an API, with functions specified and some examples of how to use these.

wrt previous remark I do not mean to disqualify the Pluto, no way, but for shortwave reception it cannot be used (as one of my projects I am rewriting my DRM decoder, which happens to be on short wave), for the region to 2 GHz I am well equipped with especially the SDRplay RSP.

Maybe if/when I am fed up with short wave and DAB I will look at things like ATV, but that is 23cm, and for experiments in the 2.4 GHz the Lime and Hackrf are - at least for the time being - more than sufficient

So, while Pluto might be a wonderful device, for the time being I do not see any advantage of buying one

hack rf is only 8 bits lime has much lower signal quality (spurious signal only 20 to 28 db below main signal) and ... pluto can send datv signal ON ITS OWN (no pc needed!!) with a special firmware ... ok no way for using the pluto on shortwave (besides adding mixers on both ports) ... but for all vhf uhf shf bands the pluto beats all other sdr with no problems ... as already said ... i am not a programmer so i can not help you with that ... but i could maybe ask another clever guy (evariste who made the datv firmware) to give us a few hints .... wait a minute i drop him a mail

[DG9BFC]

as far as i know no need to completely stop the device ... you can change frequency and gain on the fly

[DG9BFC]

maybe it would be best to have a settings box like in the rtl dongle (where you set gain, ppm correction etc) but for a first try we sure can just use auto gain ... and cause i have moddeed my pluto with a tuneable tcxo i can also live without any ppm correction (setting is done with a tiny screwdriver) ... and it is VERY VERY stable now ... i dropped a mail to evariste ... hopefully he will step in here and give us some hints

[F5OEO]

Just a quick link to start with pluto...it uses libiio and is quiete easy to work. First example could be https://github.com/analogdevicesinc/libiio/blob/master/examples/ad9361-iiostream.c . Out of this scope with dab for now, but Pluto is running an ARM (part of the Zinq) which have sometimes enough processing to handle processes like dab (around same power as Raspebrry Pi2).

[JvanKatwijk]

I added a preliminary - very experimental - version of a pluto interface. It is highly unlikely that it works, but on start up it should print a lot, telling to where in the code everything is OK

So, give it a try, and report back, then we can see whether in the end it will be successful or not

Well, it took most of my day, but the link https://www.dropbox.com/s/yv9guuj2wou1wzq/windows-qt-dab.zip?dl=0 points to a zipped folder with a Qt-DAB for windows, with a first attempt to support pluto Now, what has to be done is a. unzip the folder b. start the program qt-dab-3.4.1.exe from a command window, c. save everything that is printed and send me the output Then I can see whether or not it is worthwhile to continue with a remote development

I do not know anything about windows and I want to keep it that way, so debugging in a W environment is pretty tough It would really be much easier if you would have a Linuxbox for testing

anyway, give it a try

when starting shows an error libserialport-0.dll is missing please install new hmmm then i copied libserialport-0.dll from satsagen software in the qt fab folder and could get the soft starting now it shows no pluto device found :-(

i found another libserialport-0.dll in sdr radio console v3 folder but with that copied in qt dab folder it does NOTstart at all so i was guessing the one from the satsagen softare woud be ok ... (but maybe it is not that easy with just drag and drop the file in there?!?)

maybe evariste can step again inside and give us a hint i can additionally asc alberto who made the spectrum analyzer soft for the pluto he sure also knows a bit about how to communicate with the device at least you tried it :-)

[DG9BFC]

i got an answer from alberto (copy from mail will follow) : ...................................................................................(begin copy)....................................... hello Sigi you must add an enviroment variablle to your windows:

Variable Value IIOD_REMOTE ip:192.168.2.1

where the value is the uri of your Pluto

or

JvanKatwijk must use iio_create_context_from_uri instead of iio_create_default_context function when creating context

ciao, Alberto ....................................................(end of copy)............................................

[DG9BFC]

i hope that helps you so we finally can add the pluto :-) i did not yet add that variable (and in fact i have no idea what alberto is talking about) ... but YOU sure know what he means ... come one we finally can solve that with the hint from alberto (i hope) ... greetz sigi

i am not a programmer but ... in plutohandler cpp change line 163 it is now ctx = iio_create_default_context (); and if i understood alberto correct it should be ctx = iio_create_context_from_uri .... no idea if that is correct ... just guessing dg9bfc sigi

You should add what was said to your environment variable. Changing create_default_context to ...from_url is only meaningful if I know the url (I'll be out rest of the day and most of tomorrow)

Looking at the documentation and consulting a friend I found that the adalm pluto itself is a device that is (should be) connected to the net. My suggestion is to adapt the driver in a way that you can specify the network address, but then we have to be certain that you know that address
