People need to understand the (bandwidth) limitations of the protocol a bit better:
“In 2019, Apple published an extension called HDR which supports data rates of 4 (HDR4) and 8 (HDR8) Mbit/s using π/4-DQPSK modulation on 4 MHz channels with forward error correction (FEC).”
That quote is taken from Bluetooth - Wikipedia
what’s the bitstream of stereo audio? (24bits * 48000 samples per sec * 2 channels) = call it 2Mbps -probably not the issue
-BUT-
can HDR4 or HDR8 handle the comms between an ipad/iphone, DJ controller AND speakers? which device is the router in that scenario? (you’re building a PAN, a meshnet) I would suggest the dj controller…but all devices would have to meet the HDR8 spec for it to work because to cue stereo audio youre doubling the amount of audio data - the output stream PLUS the CUE stream -so 4Mbps system bandwidth…and you want to send crossfade move data from the controller too? all wirelessly?
now we see that a bluetooth headset/earpods is pretty magical…perhaps the magic can be strengthened to take things a step or 2 farther
