I'm using NOOBS 1.9.2 on a v1.2 Pi Zero.
I've got the wifi working. That's fine.
Bluetooth. I edited the hciuart.service file as instructed, but although the Bluetooth icon is blue on the desktop, when I click the make visible tab, the symbol flashes green, but nothing happens.
And when I click the add device tab, the window opens, but again nothing happens.
I have my mobile phone (Nokia 301) with bluetooth switched on and set to visible, but the pi cannot detect it, and it cannot detect any nearby Bluetooth devices.
So that's problem number one.
When shutting down the pi, with the redbear board attached, it cannot shut down properly and says that the system shut down is tainted.
Here's a photo from the TV of what appears on screen. The screen is frozen at this point.
Shutting down the Pi without the redbear attached, and it closes down properly.
