Problem when edit a package from python 2 to 3

Question

I am working on editing this package from python 2 to python 3 because I need use KivyMD, which only support python3. source code can be found here: [https://github.com/groner/pythinkgear/tree/master/thinkgear]

When running under python 2, it can output the desired results like this:

DEBUG:__main__:ASIC EEG Power: EEGPowerData(delta=3656, theta=5612, lowalpha=697, highalpha=3450, lowbeta=6125, highbeta=5826, lowgamma=2728, midgamma=53552)
DEBUG:__main__:ATTENTION eSense: 0
DEBUG:__main__:MEDITATION eSense: 0
DEBUG:__main__:POOR SIGNAL: 200
DEBUG:__main__:ASIC EEG Power: EEGPowerData(delta=1340, theta=5046, lowalpha=4464, highalpha=5822, lowbeta=2467, highbeta=4815, lowgamma=8844, midgamma=57809)
DEBUG:__main__:ATTENTION eSense: 0
DEBUG:__main__:MEDITATION eSense: 0

In order to make it run on python 3, I edited line 31 to this:

from io import StringIO ## for Python 3

and line 91 from:

_bytelog.debug('%04X  '+' '.join(('%02X',)*len(buf[o:o+16])), o, *( ord(c) for c in buf[o:o+16] ))

to this:

_bytelog.debug('%04X  '+' '.join(('%02X',)*len(buf[o:o+16])), o, *(c for c in buf[o:o+16]))

also I have changed all "xrange" function to "range".

But the result I get(without any error reported) is this:

DEBUG:__main__:discarding b'\xaa' while syncing
DEBUG:__main__:discarding b'\xaa' while syncing
DEBUG:__main__:discarding b'\x04' while syncing
DEBUG:__main__:discarding b'\x80' while syncing

DEBUG:__main__:discarding b',' while syncing
DEBUG:__main__:discarding b'\xaa' while syncing
DEBUG:__main__:discarding b'\xaa' while syncing
DEBUG:__main__:discarding b'\x04' while syncing

all are binary code instead of numerical result. Can anyone please tell me the reason? or is there any place I still need edit in order to make this package work in python 3? Thank you very much!!!
