SoapySDR not finding airspy after updates to raspberry pi OS #425

Closed onigiri63 closed 8 months ago

onigiri63 commented 8 months ago

I've been working on a long-term project that uses the airspyHF+ connected to raspberry pi, using the SoapySDR python library to capture the rf and track signals. The library was working fine, however I needed to rebuild the pi recently and after running the installation scripts (https://gist.github.com/songritk/b0ac5cde818d42d61a9848f3f2a5a797), SoapySDR refuses to find the airspy. I know that the airspy is connected and working, since GQRX connects to it fine and is able to see and demodulate radio, however SoapySDR just refuses to acknowledge that the airspy is connected. I've tried:

Probe device driver=airspy Error probing device: SoapySDR::Device::make() no match

I can't find a solution to this issue, it's strange that it was previously working using the installation script I linked, however now it never finds the device. I'm wondering if there was a change in the Raspbian OS that was pulled in an update, which led to this issue, however right now I'm totally out of ideas on what to do here.

What's the output of SoapySDRUtil --info

You only have the SoapyRTLSDR module (librtlsdr) installed. You need to install the https://github.com/pothosware/SoapyAirspyHF module.

Okay, I installed the SoapyAirspyHF module, and tried querying both before and after a reboot, however this is what I'm getting:

Don't use a driver key and it will auto match. SoapySDRUtil --probe Otherwise use the proper driver key: SoapySDRUtil --probe="driver=airspyhf"

onigiri63 commented 8 months ago

Do you happen to know of a better install script for SoapySDR python on the pi? Here's what I get from that:

SoapySDRUtil --probe

Sorry, no idea. The SoapyAirspyHF has the ability to automatically find a device, not sure why it doesn't work. https://github.com/pothosware/SoapyAirspyHF/blob/master/Registration.cpp#L43
