SDR# RTL433 Plugin For SDR# Now Available

[rickderby]

I have it working fine with an RTLSDR V3 and various other rtl based dongles with the parameters as defined, with either the airspy mini or R2 although it loads and I have signals no data is parsed tried various sampling rates and settings and get zero messages except every now and then fsk mode detected

Hello Rickderby

If you want, you can try saving an IQ file, replay it and send it to me if it doesn’t work.

On my version SDRSharp 1811, the Recording plugin does not open (ok in 1788) otherwise the Baseband Recorder plugin is ok in 1811.

Configure:IQ WAV SDR Compatible and 16 Bit PCM.

Start plugin

Record with signal and without window device.

You can replay with source SDRSharp:input Baseband File(*.wav) to confirm the problem.

Hi Marc I have tested it with 1711 and 1811 with dongles and all works great the baseband file made with the airspy mini does not work either the baseband file is too large to attach on here what is the best way to send it to you

Here is what i get when i press the Paly Button on the sdrsharp
What is the problem ?

 

[Marco402]

You can load it with Audacity, delete the areas without information, it shows very well you can zoom again to remove more then
export.
Otherwise you have my github address in my source files in the zip(max 10Mega).

Hello Ronenp

As I noted in the readme, I test with the 1811 version, and do not have the 1784 version but I have no problem with the 1788.

What is curious you have version 1784 and the message displays 1632?

I also checked, all dll load on sdrsharp.exe and not start.

Does this problem disappear by removing the plugin_rtl433?

Well recovered the file, the problem comes from sampleRate at 3000000 instead of 250000.

 

[rickderby]

that is the lower sample rate for the airspy mini it has 6000000 as standard even with decimation the minimum that can be reached is 750000 the R2 is greater still

I switched back to a v3 RTL-SDR dongle and this is the best I can get:

Unfortunately, I don’t have an Airspy interface to try.

I don’t understand why the software worked correctly the previous time?

For the configuration, it is enough the frequency on SDRSharp, Sample Rate at 0.25MSPS, RTL AGC and Tuner AGC.

Did the list of devices fill up well?

Do you have messages in the console "Verbose messages from RTL_433" when passing a signal?

It seems to me that the sample rate is 900001 on the dump?

I will see for an evolution in the next version.

Hello Spleen
It's a zombie window
Correction in the next version.

[Spleen]

Outstanding! I will test upon release.

Hello Spleen

Correction in the next version.

[Marco402]

Hello
Version 1.3.1.0 - 8 June 2021
- Modifications
The sample rate > 250000 is managed, 250000 is still preferable,use lowest sample rate.
Recording at device windows is only allowed at 250000.
This amendment was a request to be able to use Airspy mini that does not go down to 250000.
- Corrections
With -vvv, a window "zombi could be displayed due to received messages.

Thank you Marco that works fine for me with rtl dongles and both the Airspy mini and the airspy r2

 

[Spleen]

Sorry Marco, not sure what's going on. The zombie window stopped coming up, but no other graphs ever appear. I've cleaned out all the plugin entries from sdrsharp.config, ensured they were all turned off, stopped all tiles that didn't need to be open. I can see and hear the signals, but no graphs open any more and I can't tell if anything is being properly decoded. FYI, those IKEA messages that were appearing in the zombie window now just appear down in the Parameters/Messages window, unless I turn off Verbose:

Spleen add some decimation 16 and 32 worked for me

 

[Spleen]

Thanks, I'll give it a shot. I was under the impression that those settings wouldn't override the plugin. Do we know which GUI settings control input to the plugin and which do not?
