[RTL-SDR] Support for more than one device #95

Paderman · 2017-06-29T15:04:20Z

Is it possible to run welle.io with installed zadig driver instead original driver?

AlbrechtL · 2017-06-29T18:13:11Z

Can you explain your problem a little bit more in detail, please? welle.io runs with the zadig driver, see here: https://www.welle.io/devices/rtl_sdr

Paderman · 2017-06-29T20:10:37Z

I have a RTL2838 (R820T2, 0BDA 2838 01) stick, not RTL2832 and Zadig is installed, but welle.io say it doesn't exist a device for welle.io.

andimik · 2017-06-29T20:19:57Z

This seems to be the problem:

RTL_SDR: Found 2 devices. Uses the first one

Could you reset the driver for Interface 0 or even install the old driver in Zadig? Not so for Interface 1, please leave it as it is.

andimik · 2017-06-29T20:39:29Z

BTW: There is no RTL2838 at all ...

I try to reset the driver.

It seems, that only Interface 1 is working ☹

Ah, okay, a product name 🙂

AlbrechtL · 2017-06-30T22:43:52Z

Is your set up working now or do you still have issues?

andimik · 2017-07-01T06:48:37Z

Alternative: use another stick, they are very cheap, 5 Euro should be enough for 2nd hand ones.

Paderman · 2017-07-01T11:17:47Z

It works only with Interface 1 not 0.
In SDR#, Qt-DAB/SDR J DAB I can choose Interface 1 and it works.

I had a stick (RT820T) but I sell it ☹

Hmm, then I can't use this program then I can't choose Interface 1 😢😢😢

AlbrechtL · 2017-07-01T12:04:46Z

If you are able to recompile welle.io you can change this line in CRTL_SDR.spp from
ret = rtlsdr_open(&device, 0); to ret = rtlsdr_open(&device, 1); to use the second interface.

Paderman · 2017-07-01T18:45:34Z

Thanks 🙂 😎 🤠 the stick is working now with Qt Creator 🙂 😎 😇

Is it possible to add a switch parameter to start with interface 1 or similar?

AlbrechtL · 2017-07-02T12:46:48Z

I still don't understand why you have two devices listed but I agree that an opportunity to select the device is useful. I added it to the task list.

I recommend to start with a command line option first. In a second step some GUI functionality can be added. If you are a developer please take the job and send me a pull request!

Paderman · 2017-07-02T15:17:44Z

Thank you for your help 🙂
I use one connected stick and that have 2 interfaces and the last is working...
I can programming minimal only in C#, PHP, but that's all...

AlbrechtL · 2017-07-02T17:59:57Z

Great! I encourage you to learn C++ and than you can add a device index command line option for the rtl-sdr devices.

andimik · 2017-07-02T18:04:42Z

One of my Sticks (E4000 tuner) also has two interfaces.

AlbrechtL · 2017-07-02T19:04:11Z

Does somebody know why one dongle has two interfaces?
I mean it is obvious that in this case only the second interface works.

Is this the case also under Linux?

Paderman · 2017-07-02T21:28:24Z

I'm very sorry, but C++ is a little to hard for me 😟 C# is a little easier, VB code is nothing for me 😂 I wish I could C++ 😇

I use VS 2017 Community and it's ok for small Windows programs or UWP...

I have a "Windows Phone" and I created a simple and not finished app (UWP) and it works on PC and Phone 😂😂😂

Can you build a function to select the interface please? 😇😉
Thank you very much 🤠

It's a good question why some sticks has two interfaces...

andimik · 2017-07-03T11:32:12Z

I have no idea, but the E4000 PDF mentions PWM and i2C interface

jaap59 · 2017-07-08T14:18:05Z

Hi. With Windows 10, one (1) RTL-SDR v3 stick and Zadig 2.3 my laptop also shows interface 0 and 1. SDR# and HDSDR aren't bothered, but Welle-io is. Nevertheless on the same laptop using "rtl_tcp -d 1" (interface 1) and "welle-io -D rtl_tcp" (rtl_tcp interface) it works just fine. The laptop played both French and Swiss stations during my vacation close to Geneva. Good job!

AlbrechtL · 2017-08-03T19:17:04Z

Good news! The next top priority would be to implement the support of more than one interface.

I also think the automatic selection of the interface can simply uses the rtl-sdr interface with the highest interface number. From all reports it seems that the highest interface number is the right one.

What bothers me a lot is that I don't understand why the rtl-sdr driver reports two interface even there is only one connected.

PD1LOI · 2017-08-04T08:16:28Z

I can not recompile the file. how do you do that? Can not you equal the build of the file that set the same value to 1?

andimik · 2017-08-04T10:39:25Z

In the meanwhile use another stick. Nowadays people are selling them for around 5 EUR

PD1LOI · 2017-08-04T11:51:36Z

Why this stick just works on all other Win10 and Zadig 2.3 programs including SharpSdr and DDS 1.70 and so on. Only Welle.io does not work so I should look at this to solve this.

And this version I have.

HansJA · 2017-08-04T12:45:16Z

The rtl-sdr driver interfaces are two bulk-in usb interfaces. One is the actual device and the other one is an interface for accessing the IR remote control part of the stick.
I don't know for sure what can be done with the bulk in interface 0, the IR interface, but I think you can see the IR control stream an interpret that in order to implement what the stick itself won't.

It's probably a bit adventurous to assume something like "always use i/f 1 if it's rtl2832 based"...

HansJA · 2017-08-04T12:49:20Z

I think you should try and get in touch with other guys writing sdr utilities, and share knowledge and experience.
SDR# and SDR-J seems to work in many ways, although sonic quality when using a 2832 stick as a wbfm stereo receiver is abysmal in both.

HansJA · 2017-08-04T12:54:19Z

Adimik, I have two different sticks, the RTL-SDR v3 that the guy at rtl-sdr.com sells and an astrometa dvb t2 stick, and both have the same problem with "the wrong interface".

(One can't help but think of an Aardman animated film, "The Wrong Trousers"..)

AlbrechtL · 2017-08-04T19:50:13Z

It seems that SDR# uses a modified librtlsdr library with IR support.

Somebody can try to just copy the rtlsdr.dll from SDR# to welle.io.

It makes no difference if I use another rtlsdr.dll. It just does not work. I can customize CRTL_SDR.cpp with notepad ++ but I can not compile it.

AlbrechtL · 2017-08-06T13:13:39Z

I created a test version of welle.io with an improved auto selecting of rtl-sdr devices. It simply tries to open the first rtl-sdr device if it is not working then welle.io tries the next one and so on.

Please download the test version exe here
Warning: It is only the exe file of welle.io. You need to install welle.io first form here.
Copy the exe to your welle.io install directory e.g. "C:\Program Files (x86)\welle.io"
Run 20170805_rtl-sdr_welle-io.exe
Report your results

I tested it with the welle.io version V20170701.

PD1LOI · 2017-08-07T07:04:52Z

Thank you very much, now it works well.

AlbrechtL · 2017-08-07T19:55:26Z

I commited the code (e656145). It will be included in the next official release.

Paderman · 2017-08-12T18:25:34Z

What is if user has more than one stick on PC? 😂 😉

HansJA · 2017-08-13T10:03:38Z

An ideal receiver application should allow selecting the receiver via a menu. Hans J. Albertsson From my Nexus 5 Den 12 aug. 2017 20:25 skrev "PadMan" <notifications@github.com>:

@HansJA Can you explain in detail the use case to use more than one device, please?

HansJA · 2017-08-14T06:32:16Z

I usually have two different sticks connected, a commercial dvb-t2 stick and the rtl-sdr. In the future I envisage running an Sdrplay rsp2 in parallell with at least one stick. The use case is not wanting to connect +disconnect just to try the other receiver. Hans J. Albertsson From my Nexus 5 Den 13 aug. 2017 20:20 skrev "Albrecht Lohofener" <notifications@github.com

AlbrechtL · 2017-08-15T17:13:32Z

welle.io sees only dab sticks with the zadig driver or the airspy driver. I suppose that your DVB-T2 stick and the sdrplay stick uses different drivers and thus it is not a big deal to use it in parallel.

xenDE · 2019-06-28T14:39:32Z

Hi,

is still no device_index parameter available?

like in the rtl_sdr tools:

$ rtl_test -h
rtl_test, a benchmark tool for RTL2832 based DVB-T receivers
Usage:
	[-d device_index (default: 0)]
$ rtl_test 
Found 2 device(s):
  0:  Realtek, RTL2838UHIDIR, SN: 00000001
  1:  Realtek, RTL2838UHIDIR, SN: 00000001

best regards,
daniel

AlbrechtL · 2019-07-01T19:05:22Z

OK guys. I reopen this issue to implement this feature in the future. It is not a really difficult task and with the version 2.0 it is easy to implement. But somebody has to do it.
At the moment our main objective is to release version 2.0. This could be something for version 2.1.

tenzap · 2019-12-08T10:59:08Z

As a workaround, maybe you can try by using SoapySDR which, if I remember well, allows you to choose which device you want to use thanks to the ability to define driver arguments in welle.io (soapySDR support got some improvements in welle.io 2.1)

BTW, I guess this can be done for now only on linux when using a distribution package (like on debian) with soapySdrRtl Driver installed, since I'm not sure that the windows package ships the soapyRtlSdr driver.
