I want to quickly find the bluetooth device address (a.k.a. bluetooth address, BD_ADDR, bluetooth mac address) of a Chromebook laptop.

So far, the only way I've found is slow and not always reliable - I've posted this answer below, but feel free to provide a better solution, and I'll accept your answer.

The only way I've seen (and may rely on a failed bluetooth connection attempt or a failed "Smart Lock" setup attempt) is to find a certain warning message in the device logs.

  1. Open a tab to: chrome://system
  2. Click Expand all button
  3. Ctrl-F to find, and search for /hci or /bluetooth

  4. Note the warning of the form:

    WARNING:bluetooth_device_chromeos.cc(613)] /org/bluez/hci0/dev_FF_FF_FF_FF_FF_FF: Failed to pair device: ...

I believe the Chromebook's BD_ADDR is those 6 hex octets, typically written with colons: FF:FF:FF:FF:FF:FF

Bonus note: you can also find the ethernet MAC addresses under ifconfig of chrome://system
