In the article they say Bluetooth 5.2 “brings with it” LE Audio. Not strictly true. LE Audio is a separate specification. It requires Bluetooth 5.2 but is not part of it. We are seeing hardware with Bluetooth 5.2 but the spec for LE Audio hasn’t been released yet.
The questions I’d like answers to are:
Can LE Audio be added later as a firmware upgrade?
Will we see chips with Bluetooth 5.2 and LE Audio on the same chip and will that be a significantly more efficient implementation?
If the answer to the first question is ‘yes’ and you get a phone that’s 5.2 equipped and with upgrades for a couple of years, you get some future proofing.
If the answer to the second question is ‘yes’ and LE audio is important to you then you might be better off waiting to purchase if you can.
