Default [Q] How to know the version of bluetooth audio receiver programmatically?

Audio adapter brand is SC Z-100, it was bought on EBay. Manufactured in China.

The adapter allows me to play music files from my tablet on my main amp wirelessly. The adapter works normally (DAC so-so quality).

Adapter Package Box and Manual listed Bluetooth version 2.1. The label on the back of the adapter body indicates V3.0.

Q: Subj

A on my own Q:

I have determined Bluetooth version of my Z100 Audio Receiver in a following direct measurement.

I loaded my Audio receiver with 24/192 Flac test track, having a bit rate of about 5 MB/s. The Receiver played the track normally.

As far as v.2.1 Bluetooth has the 2.1 Mb/s speed limitation, my receiver is based on Bluetooth v.3.
