I have been troubleshooting my KrakenSDR setup with GNU Radio for approximately 24 hours. Each time I attempt to run a flowgraph using the Kraken GNU blocks (installed via Radioconda), I encounter an “Ethernet connection failed” error, and the program either freezes or becomes unresponsive.
My goal is to implement a 4–5 element antenna array for beamforming and achieve 180-degree direction-of-arrival (DOA) estimation for a course project.
So far, I have:
-
Installed the KrakenSDR GNU Radio blocks using Radioconda
-
Successfully run Heimdall independently
-
Attempted to run the Kraken DOA interface
However, I am experiencing inconsistent behavior:
-
The DOA web interface (port 5000) is often unresponsive
-
On rare occasions when GNU Radio does run, the data appears to be invalid or consists only of noise
-
This suggests that the IQ data stream may not be properly initialized or transmitted
At this point, I suspect the issue may be related to:
-
Network configuration between the host PC and KrakenSDR
-
Improper initialization of the Kraken data pipeline when launched through GNU Radio
-
Potential conflicts between Heimdall, GNU Radio, and the DOA service
Any guidance on stabilizing the Ethernet connection and verifying a valid IQ data stream would be greatly appreciated.
Also would like to mention I am not attempting beamforming at this time just trying to see spikes in the RF band so I know my SDR is alive.
