Remote setting of device time

[dmatech1]

This script seems to work flawlessly with the CVS-branded BP3AC1-1PC (UK link). The software for it has a feature to set the time on the device, but it didn't seem to work on anything beyond 32-bit Windows XP. Is there any interest in adding this if I can somehow get a USB capture of this operation?

I think I have the command sequence for that, I'll come back to you if or if I haven't found it:)

[phako]

Hm, no I cannot find it. If you have a capture, that would be very nice.

What I did was using a Windows VM on Linux, route the USB device to that and use https://www.kernel.org/doc/Documentation/usb/usbmon.txt to dump the traffic

I finally got around to testing this some and I've at least figured out some of this. Normally I'd just reverse-engineer the code, but I live in a jurisdiction that might enforce the EULA terms. I'll do a few more of these just to make sure I'm right about them.

Ah interesting. I haven"t worked on this for some time, I need to check my notes, sorry. Will get back to you

[joergmlpts]

Does this code work for you? That's for Microlife model BP3GX1-5X that I bought at Costco maybe 5-8 years ago.

[phako]

Oh, nice app, that's what I wanted to write but never came to do
