SoapyRPCUnpacker::recv(header) FAIL on Raspberry PI OS 64bit

Hello everyone,

did someone already tried running SoapyRemote on Raspberry PI OS 64bit?

I have Raspbbery PI 3B+ with SDRplay RSP1A and I was getting these errors when I tried to connect with SDR++ (also with GQRX) to it:

pi@raspberrypi:~ $ sudo systemctl status SoapySDRServer

My SW setup was following:

• Raspberry Pi OS Lite (64-bit) from January 28th 2022
• SDRplay_RSP_API-ARM64-3.07.1.run
• self-compiled SoapySDR (00e0312c3e464e1026b7c84a2359b1fea7d65796)
• self-compiled SoapyRemote (c09b2f1)

I didn't have time to debug it more and I don't have any issues when using Raspberry PI OS (32-bit).

Thank you,
Roman
