SDR# RTL433 Plugin For SDR# Now Available

[bhall7]

Hello, @Marco402,

When trying to run the RTL433 Plugin (v 1.5.6.1) for SDR# 1910, it displays a "DLL not found" error and crashes when the plugin is started.

I downloaded a fresh copy of SDR# from airspy.com (v 1910), downloaded the latest RTL433 Plugin for SDR# from GitHub - marco402/plugin-Rtl433-for-SdrSharp. Copied the three DLLs from the install\1.5.6.1 folder to C:\sdrsharp-x86 - 1910\Plugins\RTL433 folder. Plugins.xml is not modified (e.g., no "magic line" has been added). Plugin shows up in SDR#, but when enabled and started, it throws the following error:


"Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. Dll was not found."

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

I took a screen capture from install to crash:

Tried adding the three DLLs straight into the Plugins folder (not in a subfolder), tried even adding the magic line in the Plugins.xml file, but nothing I do seems to prevent it from crashing upon start.

I'm running Windows 10 Pro 22H2 on an HP ProDesk400 Mini with an RTL-SDR v3.

Any tips would be greatly appreciated.

Hello bhall7

First, have you adjusted the settings indicated in the plugin window. A sample rate too high can crash rtl433.

Marc

Marco, what setting should I adjust? I put the sample rate at 2.5 M.

 

[Marco402]

Hello bhall7

You have the settings set displayed by clicking on the Display param button, but it should work at 2.5Mhz.

Could you try version "1.5.6.1 framework 4.6" version 1.5.6.1 being in framework 4.8?

Marc

 

[bhall7]

Marco, I tried copying the DLLs from the folders 1.5.6.1 framework 4.6 and 1.5.6.1 framework 4.8 and it's the same behavior as before (plug-in is visible, but as soon as you click Start, it crashes with "System.DllNotFoundException: Dll was not found".

 

[Marco402]

bhall7, I think it lacks a dll used by rtl_433 on your pc, unfortunately microsoft does not indicate which one.

If you want, you can already try sfc /scannow in a console.

Thanks for your continued help on this, Marc. I ran sfc /scannow and it reported "Windows Resource Protection found corrupt files and successfully repaired them." (a review of the log file didn't reveal much helpful or insightful information). I then tried re-copying all of the DLLs from each of the different subfolders at a time under the main install folder to my Plugins folder and restarted and ran SDR# after each time. Every time, after clicking Start, I get the same error and it crashes. Any tips on how to troubleshoot or further diagnose the issue would be greatly appreciated. I can run the standalone RTL433 app in Windows terminal without any problems, but, I would prefer to run it in SDR# for easier use, data viewing and window management.

 

[Marco402]

If RTL_433 works in standalone mode, this is interesting information.

I would also be interested in finding the solution to this problem.

I propose you a small try, to remove rtl_433.dll from the plugin folder and compare the details of the error with and without rtl_433.dll. If you want, you send it to me (I use "compare It").

Thanks for your continued help with troubleshooting, Marc.

When I remove rtl_433.dll from the plugins folder and attempt again, the JIT debug log does not show any meaningful difference between the two (a couple of the same components reported below are in different orders, that's it). See attached for both JIT debug logs.

 

[Marco402]

I propose you a test, transfer rtl_433.dll in the file or is sdrsharp .exe.

Hello,

to fix you must simply download and install Microsoft Visual C++ 2013 Redistributable x86/x64.

Hello,

I just tried installing the Visual C++ 2013 Redistributable for both x86/x64, rebooted my machine, and I'm getting the same error:
System.DllNotFoundException: Dll was not found.

I just tested moving all three .dll files to the same folder as sdrsharp.exe and I get the same error:
System.DllNotFoundException: Dll was not found.

Download the 2015 Visual C++ Redistributable as well

Thank you! That did it! the RTL433 plugin now runs without crashing. However, I'm still trying to get it to recognize and decode a signal. The Verbose Messages window stays blank. I double-checked the gain, bandwidth, etc., and can't figure out why I'm not receiving any data. I'm able to use the original RTL_433 application via the command prompt without any problem, so I imagine there's just a setting I am missing in SDR# or in the RTL_433 plugin. Here is a screenshot of my settings:

Thanks again to all for your help!

Thanks again to all for your help!

Your welcome! Glad you got it! Try to max out the gain, then turn ON turner AGC. Also, Try the -v- option for verbose, can’t tell if it is selected in photo. I believe I read in this thread that the radio settings panel don’t matter for the plug-in. Could be wrong.

My next thing is to learn the rtl_433 application Commands, just got the program to work.

Awesome! Finally got it to work by enabling both RTL AGC and Tuner AGC. 🤷‍♂️ But, after a few minutes, it crashed with the following error:

I'm finding the native terminal app to actually do what I need it to do quite reliably (I just downloaded the most recent nightly build). If you do end up using the native terminal app, I found it useful to make use of a config file, which stores all of your parameters, so you just need to run the application and it will automatically read in everything from your config file. Attaching my rtl_433.conf file here (rename from rtl_433.conf.txt to rtl_433.conf)

Hello bhall7
I have a small problem of mail issued by radioreference since April 29th???
You passed a step thanks to Iamnewtothishobby .
For System.ArgumentException: Parameter is not valid.,
I tried with the same parameter as you, no problem,
Laffen had the same messages page 7 , it was the sample rate.
Without much conviction, now that it starts, maybe try again the 2 frameworks 4.6 and 4.8 ???

I lowered the sample rate to 0.900001 Msps and it is not crashing anymore. Just trying to find a good level for RF gain, etc.
