A was not able to run this ros node because of the following error:

     raw_data = raw_data + rec
TypeError: can only concatenate str (not "bytes") to str

In the publisher python file, when a received byte is arrived it is not converted to string before concatenation (in line 45).

the original code line 45 in the publisher.py: raw_data = raw_data + rec

this line should be this: raw_data = raw_data + rec.decode()
