SoapySDR: (1) allow user to manually enter raw sampling rate, bandwidth and decimation factor in the RX-X menu. (2) Detect networked devices not only USB ones #41

Hello,

Everything is in the title.

1) Unfortunately the sampling rates available in the RX-0 menu do not allow me to use my PlutoSDR with linhpsdr. Reception is impossible as audio is terrible, sometimes there are even some awful audio oscillations. By default the sampling rate is set to 48 Khz (KSA) but changing it to any of the other values currently offered in the RX-0 menu does not improve the situation. See the critical error message below, linhpsdr complains it is unable to set the BB Rate. Out of experience with SDRANGEL, I know for that a sampling rate of 2 and 2.5 MSA gives good results with my plutosdr but it can not be entered in the RX-0 menu as the max sampling rate supported is 1.5 MSA. For any soapysdr devices, as a matter of principle, it should be possible to manually enter the sampling rate and the bandwidth in the RX-x menu. There are just too many devices supported to figure out all use cases so better let the user enter manually his parameters

2) I sometimes use an Ethernet adapter with my PlutoSDR but linhpsdr is unable to detect it over my network despite the fact that my Pluto and my PC are on the same subnet. My Pluto is only detected by linhpsdr if connected to my PC over USB. So because some SoapySDR devices can be networked but not detected by linhpsdr automatically, it should also be possible, as a backup, one way or another to specify somewhere a hostname (or IP address) and a port number to force the detection of such SoapySDR networked device (this is how it is implemented in SdrAngel ).

ok the problem for the plutosdr is that the minimum raw sampling rate (before dedcimation/interpolation) is 2084k for for TX and for RX. Then it can be decimated/interpolated by 1,2,4,8,16,32,64.

So if a soapysdr device is detected, instead of offering sampling rate values of 48, 96, 192, 384 Khz up to 1,536 MSP better let the user enter manually a raw sampling rate (ie, min 2.084 MSP for the pluto) AND a decimation factor (1,2,4,8,16,32,64). Same story for the TX signal, add a box for the TX sampling rate (min 2.084 MSP for the pluto) and a box for the interpolation factor (1,2,4,8,16,32,64)

I am hoping to get a Pluto SDR in the next couple of weeks. I can spend some time looking at it then. -- John

satfan52 commented 4 years ago

Many Thanks John, actually there is also the decimation factor to be entered manually (values 1,2,4,8,16,32,64) So 3 parameters to be entered

Note: The TX part of the soapyplutosdr module was recently fixed and now works https://github.com/pothosware/SoapyPlutoSDR/issues/32

dj1an commented 4 years ago

Is there any Progress on this issue? Tried using Plutosdr with linhpsdr and soapy today. Noticed linhpsdr picks a way too high Samplerate for RX and TX, saturating the ethernet or usb Connection:

sample_rate selected 6000000

Manual selection of samplerate / decimation as proposed should do the trick.

g0orx commented 4 years ago

Not currently. I am too busy with other projects. The message "sample_rate selected 6000000" is not the sample rate it is actually running at. It is currently set to 768000. I do not find this is saturating the USB or the Network and is working with no problems for QO-100 at my location. I will look at manual selection as soon as I have time.

dj1an commented 4 years ago

Then there seems to be an error on my side. Maybe Soapy Lib? I watched Network throughput at different Samplingrates and got about 6 Mbyte/s at 768k and 9 Mbyte/s at 48k. In Tx Mode i can see an increase of 2 Mbyte/s at 768k and no change at 48k. All other Sampling Rates are in between this values. So it might not be a saturated link, but it seems, that the selected Samplerate of 6MS/s is being actually transferred over the network. If there is anything i can do to help debug this issue, let me know

satfan52 commented 4 years ago

John, I was able to receive correctly with my plutosdr with a samping frequency of 768000. The problem is that it only worked ONCE. After I restarted the application the audio became choppy (as if there was not enough bandwidth, but there is plenty!) and despite all my efforts (I even recompiled a fresh version) I could not make it work again. I also looked for cached files to try to clear them, the only one I found is in the .local/share/linhpsdr directory and clearing it did not help.

Also TX does not work at ALL with my pluto and linhpsdr.

Can you share with us the exact TX and RX parameters that you use with your pluto (other than the sampling rate of 768000) ? as well as what are the relevant cache files to clean when we get into trouble ? I am using Ubuntu 18.04 LTS and I have no errors when I compile your software

Thanks Regards Peter

Note: I am able to receive and transmit fine with pluto, soapysdr, the SoapyPlutoSDR module and sdrangel, so I am 100% confident that my SoapySDR installation is OK.

satfan52 commented 4 years ago

Crashes to on some ocassions when trying to set the sampling rate to 768000

receiver_change_sample_rate: from 6000000 to 768000 radio=6000000 Segmentation fault (core dumped)

I am sorry but in my environment, Ubuntu 18.04 LTS, using linhpsdr with SoapySDR and plutosdr is just not feasible for sustained operation. Linhpsdr crashes all the time and audio is choppy 90% of the time (I use Pulseaudio). Linhpsdr works ok with my redpitaya (metis/hpsdr) in both TX and RX modes but with soapysdr and pluto we are not there yet very very unfortunately.
