The issue I'm having is with my Raspberry Pi 3. I'm running this CLI-only with the Raspbian Jessie Lite build.

At some point in using this device, my Bluetooth address changed to AA:AA:AA:AA:AA:AA. I believe this is preventing me from pairing Bluetooth devices. I was able to pair it in the past, but now it does not see anything when scanning.

I'm trying to add a Flic button to this Raspberry Pi 3, but for some reason, when I'm running the scanner utility and then press the Flic, it's not pairing. I was able to pair another Flic button with this Raspberry Pi 3 just earlier this week. Sadly, I already unpaired it so I cannot test if it still works.

pi@Raspberry-Pi-3:~ $ hciconfig -a

Strangely, I have two Raspberry Pi Zero W devices and both of those pair just fine with the same Flic buttons.

Another thing is the bluetoothd version is a lot higher on the Raspberry Pi 3 compared to the Raspberry Pi Zero W devices.

pi@Raspberry-Pi-3:~ $ bluetoothd -v
5.43

versus

pi@Raspberry-Pi-Zero-W:~ $ bluetoothd -v
5.23

What can I do to fix this on the Raspberry Pi 3? I assume it all traces back to the Bluetooth address being AA:AA:AA:AA:AA:AA.

The issue is Bluez version 5.43 on this version of Raspbian.

You need to downgrade to 5.23, the standard version for the Jessie build, to be able to use Bluetooth properly. This is probably caused by an apt source.

Check /etc/apt/sources.list and /etc/apt/sources.list.d/* to see if any of the files in there are pointing to test releases.
