Scales Integration

Muzzargh · February 8, 2022, 2:28am

OK, upgraded to 5.3.6 (painlessly may I add ).
I’ve added the Action, Automation Command and Rule as per the tutorial. I’m thinking I need to get the format right in the properties of the scale.
Here’s what I have so far:
Scales Properties

And this is the message coming back from the scales (after sending the W in PuTTY):
PuTTY

One other thing I’ve noticed is that the ‘Test’ option doesn’t become available where the Scale is added?

Tried this as well:

Scales Properties-2

Still not working as expected.

I have a barcode reader/scanner, do you think that might be interferring with the scale data?

Muzzargh · February 8, 2022, 11:27pm

From the scale.log:

Will the scale.log show data returned from the scale?

Muzzargh · February 26, 2022, 10:14am

I’ve tried ##.### to match the returned data in putty but still no joy with SambaPOS.

Muzzargh · March 14, 2022, 8:53pm

Still can’t get this to work. One thing I’ve noticed is that each time I press the ‘scale’ button (the one I created to send data to the scale) there are 7 entries in the scale.log, doesn’t seem right to me.

So I’ve installes a Serial Port Monitor and this is what I get (for a weight of 125g)

30 30 2E 31 32 35 0D 00.125.

82 30 30 2E B1 B2 35 8D ‚00.±²5

The top is through PuTTy after sending the upper case W, the bottom is what happens through SambaPOS. Could this be an installed language mismatch?

Muzzargh · March 28, 2022, 2:52am

If I check the ‘Override Windows Regional Settings’ checkbox

Language

I get this (which is the correct weight) but it has a leading comma.

82 30 30 2E 30 39 30 8D ‚00.090

Still nothing comes up in the keyboard input box.

Muzzargh · March 28, 2022, 2:56am

Will checking the ‘Override Windows Regional Settings’ checkbox have any detrimental effects?

Muzzargh · May 6, 2022, 8:46pm

I’ve tried heaps of combinations of RegEx but can’t get anything to work.
Any suggestions would be appreciated.

Memo · May 6, 2022, 9:55pm

if the decimal is always present, [0-9]+\.[0-9]+ should get you the last part after the comma

https://regexr.com/ is my go-to playground

Muzzargh · May 7, 2022, 12:48am

Tried that but still nothing. I did notice in Scale.log that the date format is US though:

Today in the 7th of May

5/7/2022 12:46 PM
5/7/2022 12:46:31 PM Custom Scale>Data:W,COM1

Which POS scale device are you using? What version of SambaPOS are you using?

I see in putty just the decimal gets passed. For the other strings with more characters, where are those coming from? Putty? In POS?

Maybe I can mock something on my end, attach a debugger and see what’s going on inside, but I need good test data.

Is this look like the scale you’re using:

Muzzargh · May 7, 2022, 1:57am

That looks like it.

I’m on 5.3.6

Cheers.

Memo · May 7, 2022, 2:23am

Looks like I found the right docs. Let me comb through them and see what’s going on under the hood. I’ll be in touch.

Muzzargh · May 7, 2022, 2:46am

Awesome, thanks for your help

Memo · May 8, 2022, 7:09am

Here’s a test utility I whipped up that will log the responses from the scale. Any responses from the scale will show in the right-hand text box.

Select the COM port to which the scale is connected.

I have set the other options to the defaults as specified in the manufacturer’s documentation so they shouldn’t need to be changed.

When you click “Start”, a timer will be enabled at a 1s interval. When the timer ticks, the init string will be sent to the specified COM port. Once a response is received, the timer will restart. This will keep going until “Stop” is clicked.

Firstly, I’d like you to select the “Emulate POS” option. This will create a connection that mirrors how SambaPOS does it.

Click “Start”, weigh a couple of things then click “Stop”. In the executing folder, rename log.txt to log_pos.txt before continuing and set aside to send me.

Then deselect “Emulate POS”, click start and weigh some more things then click “Stop”.

Zip log.txt and log_pos.txt and send to me. I’ll have a look at the responses and go from there.

Binary is found in the bin directory. Source code is included.

Wow!!! That is awesome, cheers.

It’s 7pm here so I’ll try it after work tomorrow and report back.

Muzzargh · May 10, 2022, 6:20am

Sorry for the delay.

When I click Emulate POS I get a Port is already open error:
Port Open

Nothing else is running, if I close the app then run PuTTy I can access to port fine.
If I uncheck Emulate POS nothing happens. I tried typing a W, then I tries using PuTTy and got access denied error. How do I send the W in this mode?
