- Thread-topic: Future iOS devices' backward compatible with Bluetooth 2.1 + EDR accessories
I think there is a bit of confusion here. Standard BR/EDR is not going away any time soon, and probably never. Bluetooth 4.0 introduced a new mode (Bluetooth Low Energy) while still advancing and promoting classical Bluetooth. You cannot do things like stereo streaming with Low Energy, so your fear is unfounded. Backwards compatibility is here to stay, and the 2 radios, modes and protocol stacks should be able to coexist in harmony for the foreseeable future.

Subject: Re: Future iOS devices' backward compatible with Bluetooth 2.1 + EDR accessories To clarify, I really have 2 questions: A) When will a new specification of Bluetooth (e.g. Bluetooth 5.0) stop being backward compatible to Bluetooth 2.1 + EDR? When do you think this will happen? A) When do you think future iOS devices will STOP being backward compatible with Bluetooth 2.1 + EDR accessories? iOS devices skipped Bluetooth 3.0... what's the likihood that they will skip 5.0?

I'd appreciate any insight you can share. + The Core Bluetooth framework is built on Bluetooth 4.0.

Frankly, our biggest worry with Bluetooth 2.1 + EDR is its "shelf life" from Apple's standpoint. How much longer will future iOS devices be backward compatible with Bluetooth 2.1 + EDR accessories? |
