GNURadio Companion: Driver not found

[SnkMtn000]

RPi4b8gb - Installed librpix and SoapySDR_rpitx, rebooted per the instructions. Module is in correct directory.

Fired up GNU Radio Companion and cannot find any modules for rpitx.

At a command prompt executed SoapySDRUtil --find

No devices found!

Hi.
librpitx should not be installed separately. It is already in the project source.
I don't know how it could interfere if it exists outside the project.
Check the version of SoapySDR, maybe the plugin directory is not the same.

You need to copy here!

Getting closer,... Guessing I should use a osmocom Sink and call the "rpitx". Testing,...

I'm glad you were able to install it!
The driver still does not work correctly. When it transmits it has regular breaks (glitches). I still haven't been able to solve it. RPITX does not consume data constantly. I suspect it is due to interruptions in the operating system. If so, I'll have to use a real time kernel or something similar.

I am currently moving to a new house. When I am completely settled I will resume development

[SnkMtn000]

After you get settled, how do you use the driver as a Soapy Custom Sink, or otherwise? Thanks.

I have only tested it with sdrangel as soapy sink
