Many Bluetooth speakers support both they can be used as a hands free for a phone as well as for playing music. A2DP is unidirectional stereo audio for streaming music and similar tasks. HFP / HSP is mono audio in and mono audio out for phone calls and the like. This is fortunate as pairing got much easier from 3.0 screenshot appears to show a Bluetooth audio device supporting one or both of hands free profile and headset profile (that's the "hands-free audio" device) and A2DP (that's the "audio" device). It is rare to come across a computer with Bluetooth hardware older than 3.0 still in frontline service. Bluetooth LE launched as part of Bluetooth 4.0. Bluetooth LE is becoming increasingly important as certain classes of devices are moving to Bluetooth LE, notably including Bluetooth mice and keyboards. If a device lacks Bluetooth LE (marketed as "Bluetooth Smart") support then it cannot communicate with other Bluetooth LE devices.
Both devices must support a particular Bluetooth profile to use that profile. Bluetooth 5 is slowly finding its way into the latest notebooks - the ZBook Studio x360 G5 I am writing this reply on has an Intel Wireless-AC 9560 setup which supports Bluetooth 5.īackward compatibility on Bluetooth tends to be pretty good, though you only get the lowest common denominator of what both devices support for obvious reasons.
