- arcticbull 5y agoYes, even the 5.0 LE PHY is 2Mbits/sec and I believe that's shared between upstream and downstream. We're talking a total of 175kB/sec, split up and down [1]. I doubt that's sufficient for what you're suggesting. [1] https://www.bluetooth.com/blog/exploring-bluetooth-5-how-fast-can-it-be/ https://www.bluetooth.com/blog/exploring-bluetooth-5-how-fas...
- rasz 5y agoyou misunderstood, he means devices switching from A2DP profile to HFS/HFP the second you want to use microphone
- arcticbull 5y agoAh, I see, thank you.
- solarkraft 5y agoThis is purely a spec issue. At first there was the abysmal Headset Profile with audio at 8kHz (SCO Codec). Maybe that was the quality of telephony generations ago, but I find it barely intelligible (and definitely not useable). They then followed it up with the Hands Free Profile using a version of the SBC codec at 16kHz. They call it „high quality“ but it still sucks and is barely usable (that companies who are even pushing proprietary codecs for Bluetooth audio haven’t really attempted to fix this [FastStream is a one-way solution] is mind boggling to me). Maybe, just maybe, LE Audio will not actually suck for audio recording. Maybe.
