Everyone,

I have added a attrs line to /etc/udev/rules.d/60-libsigrok.rules, below the line for the UT612, of course not commented out.

I then reloaded the udev stuff.

I also created a 99-ut612.rules file in /etc/udev/rules.d, then reloaded the udev stuff again.

One thing I had in that 99 file was to create a symlink:


/dev/ut612

Which is a symlink to: I created that file to make sure permissions to /dev/hidraw0 were correct.

/dev/hidraw0

Which I now have.

But any attempt to get anything from the meter, such as:

sigrok-cli --driver uni-t-ut612:conn=hidraw0

Results in an error stating the port number could not be got from /dev/hidraw0.

With help from this list, and some help from copilot, I have made some progress, but copilot tells me it looks like the driver is not sending what it calls the 'poke' message when I specify the driver.

But today copilot has been particularly prone to telling me the wrong thing, and then giving me the right information when I challenge it and tell it it is talking rubbish.

And it keeps forgetting I can't see and asking me to look for the computer icon in the display.

So I think we can relax, AI is not going to take over the world, just yet.

I will work on this again tomorrow.

Mike,

Sorry, yes, no no serial port.

If I have this correct, then your command line should be something like:

sigrok-cli --driver=serial-lcr:conn=10C4:EA60 -O analog


However, my meter is a HID version of the UT612, and as such does not create a virtual serial port, so the usual 9600 8N1 parameters are not relevant.
