If your device is stuck on "Authenticating" the following has been reported to work:

1. within the file /etc/bluetooth/main.conf under [Policy] check the existence of AutoEnable=true
2. Comment out below line in /lib/udev/rules.d/90-pi-bluetooth.rules by prefixing "#" the line ACTION=="add", SUBSYSTEM=="bluetooth", KERNEL=="hci[0-9]*", RUN+="/bin/hciconfig %k up"
