Product name BikeAudio -> "Resound" (the device isn't bike-specific — works at
home, backyard, camping, parties, group rides). This is the A2DP advertise name
the phone connects to: sink.start("Resound"). All banners/comments + README
updated. (After reflashing the sink, the phone must forget "BikeAudio" and
connect to "Resound".)
Firmware vocabulary clarified (the old hub/sink/source was confusing —
"source" read backwards since those boards SEND audio):
hub_s3.cpp / env hub_s3 -> hud.cpp / env hud
board_sink.cpp -> sink.cpp (env sink)
board_source.cpp -> broadcaster.cpp (envs broadcaster_headset
0x11, broadcaster_speaker1 0x10,
broadcaster_guest 0x12)
hub_proto.h -> bus_proto.h
default_envs = sink + the three broadcasters. All envs build clean.

|
; Roles (one ESP32 can't be A2DP sink+source, and a source reaches one speaker,
|
|
; so the work is split across boards sharing an I2S audio bus + an I2C control bus):
|
|
; SINK - iPhone connects here (A2DP in) -> drives the I2S bus as master
|
|
; BROADCASTER - reads I2S -> A2DP-streams to ONE speaker (one per channel)
|
|
; HUD - ESP32-S3 round touch LCD; control panel over I2C
|
|
;
|
|
; Channels are brand-agnostic: Headset / Speaker 1 / Guest (discovery picks the
|
|
; real device per channel). Build one: pio run -e sink | -e broadcaster_headset
|
|
; | -e broadcaster_speaker1 | -e broadcaster_guest | -e hud
