I could not restart the music player at 19.51, the same at 20.00 and 20.04.
When I pressed the play button on the helmet (long press of 2 sec on volume up), the bluetooth of the phone was disconnected from the bluetooth helmet and the command only connected the intercom and the phone but the music player did not start.
Doing the same thing at 20.05 the music player has restarted.
The mtklog directory is 2GB, (1.3GB zip file)
Do you need all the zip file?
Or can you indicate which file you need in the mtklog directory?
