Rtl_433: feat-soapysdr branch: Hackrf not decoding/detecting any devices

[ghost]

Recently built the feat-soapysdr branch, and using the rtl-sdr or the hackrf, neither radio seems to detect or decode any of the nearby devices, however, switching to master with just the rtl I can get detections. I saw that in January there was mention of merging feat-soapysdr and was wondering if there was any movement on that...

or, perhaps some ideas as to why I'm not getting any demod of devices?

Thanks in advance.

I guess you would need to set the gain values. Also the value range is not optimal and (depending on the hardware) you will need a very good signal.

Did you solve this with setting gain values?

I successfully detected devices with the HackRF one. The relevant changes i made to the example .rtl_433.conf:

device "driver=hackrf" # default device "" did not work.
gain "LNA=40,AMP=14,VGA=30"
sample_rate 1000k

where:

• AMP = RF (0-14 dB)
• LNA = IF (0-40 dB, 8 dB steps)
• VGA = BB (0-62 dB, 2 dB steps)`

Then I launched: rtl_433 -G

Great! Thanks for the feedback!

can you be more precise ? :)
i make rtl_433.conf with data which you said and i am unable to run it , where i am wrong? :)

@y0d4a if SoapySDR is working (check SoapySDRUtil --make) then setting the device / -d is all that's needed. Please try a few things and www.catb.org/~esr/faqs/smart-questions.html#beprecise

yeap, with -d "" i successful start it...
thank you!
