ASD shows Bluetooth failure – is this a problem? (MacBook Pro 2014 15")

I don't know much about Bluetooth, use it only to occasionally to connect speakers to MacBook Pro. Running Apple Service Diagnostic on a recently purchased 2014 15" MBP, it says FAILED:

Bluetooth (test #2) - MAC Address Verification Test
- Verifies the Bluetooth MAC address is not all 00s or all FFs.
ERROR -- 13 [MAC address mismatch] -- TEST FAILED

Several tries, same result. Does anybody know what this means? I’ve run ASD on several other Macs, never seen this result before. Bluetooth devices (speakers, iPhone) connect to the Mac okay; also a Logitech keyboard is listed in Bluetooth Preferences, so the previous owner must have used that. Is this likely to cause some kind of problem?

Edit: Found how to get MAC address, which is 78-9F-70-7A-69-FF. Not all 00s or all FFs.

On second thought, never mind…. Apparently it was a problem with the testing software. I had Apple Service Diagnostic – the correct version for this MacBook Pro – installed on an external USB SSD, which has been working fine as a backup drive. But I also wanted to see how ASD works from a USB Flash Drive (thumb drive). So I installed it on one, and tried running it. It worked fine – and all the tests passed, twice. So there must have been something wrong with the install on the USB drive. There was also a problem reported from the Interactive portion of ASD, which I'm now going to run again from the Flash Drive. Maybe that one will turn out to be a false alarm as well.

I tried to remove this post, but apparently it's too late to do so. So I'm sharing the lesson I learned today.
