hexadecimal numbers over UART

[BL007]

You tried hexlify instead of unhexlify.

OK, this works too.
I can't read. Sorry!

You may need to DIY. Assuming you really want hex: you wrote

Which function makes from '53006400C845' => b'\53\00\64\00\C8\45' or leastways from '53' => b'x53'?

b'\53 is not the same as b'x53'

You could do this:

Code: Select all

def foo(a):
    a = iter(a)
    res = ''
    try:
        while True:
            res = ''.join((res, '\\x', next(a), next(a)))
    except StopIteration:
        pass
    return res.encode()
answer = foo('53006400C845')
print(answer)

This produces

Code: Select all

b'\\x53\\x00\\x64\\x00\\xC8\\x45'

Note that the double slashes are artefacts, as demonstrated by:

Code: Select all

>>> for x in range(5):
...     print(chr(answer[x]))
...     
...

x
5
