Error with HEADLESS

1

Everything is fine with QA40x.exe and QA40x.exe -C, but QA403 does not work with QA40x.exe -HEADLESS.

There are three kinds of faults:

1, The Link LED is not on with QA40x.exe -HEADLESS (USB is connected before the command, and voltage is correct, >4.9V). Link LED is on with QA40x.exe and QA40x.exe -C.

2, Command GET /Status/Version works, but there are some errors.

Headless operation specified. Closing the console will close the application.

Hi @Thomas, as I remember, the -headless was put in a log time ago for a customer using the product in a factory. I will put it on the list to be looked at, but for now you are correct there does seem to be some issues. Even setting to Default throws an exception.

Thanks very much for report this!

Thanks for your attention.

Before the issue is solved, can I use some old FW and SW version to support headless?

I tried SW 1.215 + 1.1.6.8 and 1.202 + 1.1.6.8, no working.

Hi @Thomas, it looks like -HEADLESS was first debuted in release 1.167 in November of 22. That release is on GIT. it will roll your firmware back to 58 automatically.

Just curious, is there a specific need you have for headless that minimizing the window can’t accomplish?
