OK, I feel really dumb asking this question, but… how are you replying in line with previous messages?
On Windows, the USB driver allows multiple applications to be connected to the device. So you can actually connect limeGUI and use it to change parameters and experiment while the GRC graph is running. (CLKGEN/sampling rate should not be modified while the data streaming is active, as fluctuation in clock may cause garbage or data shift in streaming protocol.)

That sounds great. I may have some setup issues. I started GRC and began listening to my favorite station, then opened the LimeGUI and tried to connect to the device. Usually I refresh the device list and then select the one I have. For some reason I can’t get through that operation. I can connect when the graph is stopped.
I tried connecting through the LimeGUI first, with GRC open and the flow graph stopped. That works. But when I then try to start the flow graph, it does not start. Here is the GRC log for that event:

I did find the way to save to a .ini file. Thank you.
Oh, LimeSDR mini is using libusb driver on Windows, libusb supports only one application at a time to connect to device.
I was thinking about the LimeSDR-USB board, it’s default Cypress FX3 driver allowed multiple connections.
Anyway, that means you’ll have to use .ini files for custom configurations.
Hello, I just tried referencing the .ini file using:
LOAD_CONFIG=“C:\Users\ngriesert\OneDrive - southern.edu\Desktop\GNU Radio\LimeSDR_LNAH_Fs_2p4M.ini”
The log below indicates:
[ERROR] LoadConfig(“C:\Users\ngriesert\OneDrive - southern.edu\Desktop\GNU Radio\LimeSDR_LNAH_Fs_2p4M.ini”) - file not found
I have tried putting the file in different locations and have double checked paths (copy and pasted), and don’t see an error. Any advice?

I suspect the problem is Windows paths use ‘\’ as separator, which means somewhere the characters might get escaped (meaning \n become new line symbol instead of two letters). Try either replacing ‘\’ with “\\”, or ‘/’ symbols.
