sfScope crashing without warning
« on: May 04, 2020, 08:51:20 AM »
Hi I'm facing a problem with the sfScope when I change to the server mode.

Here's the step-by-step proess:
1. Open sfServer64r
2. Open sfScope64r. Go to Settings tab and click Connection. Then change the mode to Client <- -> Server and press connect. (I do see check mark on the connect box and Client 0 shows up on sfServer)
3. Press open on the sfScope (USB open box has a checkmark now), upload firmware and press capture.

After a second or so, the oscilloscope LED stops flashing. Then the checkmark on the USB open disappears. When I press open on the sfScope after the checkmark disappears, sfScope closes without any warning. Is there any way to fix this issue?

Thank you.

Hello.

A similar problem was solved in the latest software release. Could you download the lastest version (2.0.16) and try again?

Hi,

The problem arose initially with the new version. I had tried deleting, re-downloading and installing, but it stlll does not work.
My initial goal was to run histogram.py (python api) but I could not even get to that step as the software consistently stops responding when I change it to server mode. Client connect information in the .py file corresponds to the one shown in the sfServer.

When I change the sfScope connection from USB to server and connect, I see Client 0 in the sfServer. But when I run any .py script, Client 1 shows up, so now I have both Client 0 and Client 1 shown in the sfServer. I don't think this is what it's suppose to be or is it correct to see both clients?

Thanks.

Two clients that show up in the sfServer window are correct -  first client is the software 'sfScope', second is through the API (Python script).

Please let me know some information about your system as we try to duplicate the issue on our side... What is your operating system (Windows, Linux, Mac) and Python version (it should work with 2.7.x)?

Yes the operating system is Windows 10 with sfScope running 64-bit administrative mode and the python version is as follows: python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40) [MSC v.1500 64 bit (AMD64)] on win32.
