AttributeError: 'miband' object has no attribute 'artist'

[janvda]

I successfully connected to my miband 4 using program:

python miband4_console.py -m XXXX -k XXXX

I then navigate on my miband to the music menu
and if I then select the first item Get general info of the device from the curses menu it is reporting below error:

Possible solution:

call setTrack(MUSICSTATE.PAUSED) during initialization of the miband this will set all the music attributes so it won't report an AttibuteError anymore.

So I added line 184 (= self.setTrack(MUSICSTATE.PAUSED)) in miband.py which fixed the problem
