Syntax error for "root = Tk()"

[dlwaddel]

Yeah!!! It runs, after I made some changes to get the GUI window working. I added a few print statements to follow progress. Still fails to connect.

Some of the results:

****
Test button MAC: b'MAC\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'

IP is: 192 . 168 . 0 . 168

UDP-IP is: 192.168.0.168

Test button device address: ('192.168.0.168', 50000)

*** and then I get the device not found message. Looks like either the socket is not working as expected or the UDP port has changed. I have a query out to a forum for the radio asking what is the default UDP address.

I'm puzzled about the single quotes around the IP address in the "device address". I do not see where they come from or even if they are a problem.

In the mean time, I'd like some input on setting the window, if you are not fed up with me yet. :)

Here is the unaltered code:

# ----------------------------------
#    User Interface

def close():
    sock.close()
    root.destroy()
    root.quit()
    
root=Tk()
root.title('Bootloader 2.1')
x = str((root.winfo_screenwidth() - root.winfo_reqwidth()) / 3)
y = str((root.winfo_screenheight() - root.winfo_reqheight()) / 3)
root.geometry('400x300+'+x+'+'+y)
root.maxsize(400, 330)
root.minsize(400, 330)
root.protocol('WM_DELETE_WINDOW', close)

The resulting error:

Error:
Traceback (most recent call last):

_tkinter.TclError: bad geometry specifier "400x300+573.3333333333334+293.3333333333333"

My guess is that the intent is to place the GUI in a place dependent on the screen size. Also, I suspect the geometry specifier should be an integer, since it is pixels. I modified the code to have fixed values for "x" and "y" or 100 each. That put the GUI in the upper left of the screen.
