I had my V2p4 connected via USB to NanoVNA saver doing many S11 and S21 measurements running on latest FW from few days ago and it was all working fine. Had started and stopped both the software and the nano many times. Then I left it on last night since it was calibrated and measurement I hadn't finished and I wanted to keep it at a constant steady state temperature to finish later.
When I came back in the morning, the NanoVNA-Saver was presenting weird data when I would do a scan. Thinking maybe there was some bug that presented itself only after being on many hours, I powered off my V2p4, shutdown (hard power off) then restarted the computer, turned the V2p4 back on, and upon attempting to connect NanoVNA-Saver to the V2p2, the console would print the error:
"Error reading version registers":
Then quits.
Running the V2p4 stand-alone still seems to function.
Thoughts ?
