RTL-SDR setup assistance

[Sandman2001]

I recently purchased a RTL blog V4 and working on configuring to connect to a WH65B (previous discussion #3002). I am running on WSL's newest version. I have installed SoapySDR and binded the usb to the linux terminal through powershell. sandera2@DESKTOP-P1P04CT:~$ SoapySDRUtil --find

Installation steps for RTL
first started with sudo apt-get install rtl-433
went into build folder and tried following the steps in this video

got this:

`sandera2@DESKTOP-P1P04CT:~/rtl_433/build$ sudo make uninstall

i can access the help command from the cli and run stuff, but no sensor data returns

currently stuck on what to address

[zuckschwerdt]

Did you try a binary release? You don't need SoapySDR for an RTL-SDR and you likely don't need WSL.

Seems like threads support didn't work when building in WSL (the output_rtltcp.c warning is a clue. not sure though why that return NULL is skipped). But you didn't use that build anyway then :)

[Sandman2001]

still stuck
p.s. I adjusted sample rate to 250k from 25k and still no change

[zuckschwerdt]

Try to get more reporting with just rtl_433 -Y autolevel -Y magest -M level -M noise -M protocol

But really I guess that the librtlsdr.dll is not updated for the Blog v4. Find a DLL updated for the RTL blog V4 and replace it in that dir. Should then work as expected.

[Sandman2001]

I wasn't able to reproduce the LIBUSB error shown above, but I adjusted the antenna while running the program to see if anything would change and confirmed some response as seen in the last debugging run. Still have yet to update the .dll files so I will let you know if anything changes with that.

[zuckschwerdt]

The levels look like an active band. Noise levels above -15dB are not good, might be a busy band or a bad antenna, levels below -30 dB would be dead silence.
