Re: Using the AVNA with the nanoVNA-saver control program
Hi Mike - Interesting errors. I do not see that under Linux. The n-saver program has a lot of warning/error/debug statements, that do not do anything on the graphical interface. Under Linux, these go as StdError to the "terminal", if I start the program from there. This has been quite helpfu at times. I don't know if that works under OS-X or not. You might see if that could help.toggle quoted messageShow quoted text
I don't see that error phrase in the n-saver code, so it must come from PySerial package. One thought is that it looks like a timeout error. The AVNA is not as fast as the nanoVNA in getting 101 points measured, and serial response from the AVNA is held up until that is finished. That was the issue that required the command buffering in the AVNA. The timeout amounts probably can be programed with a PySerial call. I'll do a bit more hunting on that one to see anything hops out that we could do.
By the way, the command buffering does not slow down the time for the AVNA to receive a command; it just is not acted on and responded to while the AVNA is measuring.
I'll look around in the program. Bob
