Confirmed live tonight that the Si4684's automatic front-end tuning
(FE_VARM/VARB properties) is measurably suboptimal on this board: a
129-value ANTCAP sweep (0-128, AN851 Appendix A) at four different FM
frequencies found antcap=102 beats auto-tune by +6 to +11 dB RSSI and
+3 to +11 dB SNR everywhere tested, consistent with the front-end
network component mismatch already logged in
docs/si4684-rf-investigation-report.md — the board's actual matching
network differs from the AN851 reference network those auto-tune
constants were derived from, so a fixed empirical override
compensates for a gap the chip's own algorithm can't see.
Wiring, bottom to top:
- Si4684Driver::tuneFm() already took an antCap byte; threaded it
through core::ITuner::tuneFm() and si4684::Si4684Tuner::tuneFm() as
a new parameter (default 0 = auto, unchanged behaviour for every
existing caller).
- TunerService::tuneFm() takes an optional override instead: omitted,
it falls back to a new defaultFmAntCap_ member so every ordinary FM
tune (seek, scan, station recall, live UI) benefits automatically
once calibrated, not just calls that pass antcap explicitly.
- POST /api/tuner/tune gained an optional "antcap" field for sweeping
live without touching the saved calibration.
- POST /api/tuner/calibrate-antenna commits a sweep result: writes it
to the 24AA025E48 EEPROM's user-writable region (word address 0x00,
separate from the factory-locked EUI-48 at 0xFA-0xFF) via a new
Eeprom24aa::writeFmAntCap()/readFmAntCap() pair, and immediately
updates the live TunerService default — no reboot needed to take
effect, though HardwareBootstrap::boot() also loads it at every
boot so it survives power cycles. Same net::AntennaCalibration
function-pointer bridge pattern as PhoneStreamSink/BleProvisioning,
so components/net stays free of eeprom24aa headers.
Verified end to end on hardware: swept and found 102, saved it via
the new endpoint, confirmed the live default changed immediately,
then power-cycled and confirmed the boot log reports "FM ANTCAP
calibration loaded: 102" and a subsequent default tune reflects it.

Two independent live-hardware bugs found testing on real DAB signal
tonight (board reconnected after this session's feature work):
1. Si4684Driver::fetchDabServiceList() double-counted the already-
consumed SIZE field when computing the body offset: it added a
phantom "List Size(2)" on top of the 7-byte STATUS/SIZE header
already stripped out, shifting the service-count byte and every
service entry by exactly 2 bytes. AN649 documents SIZE/DATA_0/
DATA_N generically for GET_DIGITAL_SERVICE_LIST and defers the
actual DAB payload layout to a supplemental "Digital Services
User's Guide" we don't have, so the previous "AN649 Table 14"
citation for that layout was never actually sourced from AN649 —
it was guessed. Re-derived the real layout by cross-checking
hitech95/si468x_dab_receiver's si468x_core_cmd_dab_get_service_list()
(a working Linux driver for the same command), which also shows
the payload is SIZE-2 bytes, not SIZE bytes — fixed the read-length
sizing (payloadSize+5, was +7) to match. This is what made
GET /api/tuner/services always come back empty even with a locked
ensemble.
2. SetupWebServer registers 41 HTTP routes but httpd_config_t::
max_uri_handlers was still 40 (set before several endpoints landed
this session). esp_http_server's httpd_register_uri_handler()
fails silently past the limit, logging only a generic
"no slots left" warning with no indication of which handler was
dropped — the 41st and therefore last-registered route,
POST /api/stations/tune, was silently unroutable (404) on every
boot since whichever commit pushed the count past 40. Bumped to 56
for headroom.
Both confirmed on hardware: fresh flash boots with zero httpd
warnings; DAB service list fix not yet re-verified against a live
ensemble pending user retest (board was between test sessions).

Wraps ESP-IDF's official wifi_provisioning manager (BLE transport,
protocomm Security1, NimBLE host) so a phone can join the device to
Wi-Fi over the ESP32-S3's own onboard BLE radio, without first
connecting to the 192.168.4.1 SoftAP. Chosen over a custom GATT
service specifically so the existing generic "ESP BLE Provisioning"
iOS/Android apps work today, before the dedicated DigiRadio app
exists — same standard protocol either app would speak.
net::ble_provisioning::start() is additive, not a replacement: it
runs next to the current SoftAP + POST /api/wifi HTTP route inside
NetBootstrap's startSetupMode(), and failing to start it is
non-fatal (same pattern already used there for the SigmaStudio TCP
bridge) — SoftAP setup keeps working either way. Proof-of-possession
is the device's own serial number (same source as the SoftAP SSID),
so pairing requires reading it off the unit rather than being wide
open. On WIFI_PROV_CRED_SUCCESS the received wifi_sta_config_t is
converted to the same core::WifiCredentials type the HTTP handler
uses and saved through the same ISecureStore, then the device
reboots into STA mode — one persistence path regardless of which
transport provisioned it.
BT1035 is unaffected: it's a separate UART-attached classic
Bluetooth module for A2DP output. This uses the ESP32-S3's
independent internal BLE controller, switched to NimBLE (smaller
footprint than Bluedroid, the only host stack needed for a single
peripheral-role GATT service). App binary still has 33% free flash
after pulling in wifi_provisioning/protocomm/NimBLE.
Verified: idf.py build, doxygen (0 warnings), check-manual-sync,
check_si4684_blobs, ctest (19/19) all green. Not yet tested with a
real BLE provisioning app or on hardware — board is disconnected
this session.

New endpoint accepts chunked, header-less, 16-bit LE stereo PCM @ 48 kHz
in the request body and writes it straight to the shared I2S sink for as
long as the connection stays open. Chosen deliberately unencoded (no
MP3/AAC/Opus decode) to keep this path as simple and low-risk as
possible — the companion app controls the encoding on its side.
Extracted the I2S TX channel that used to be owned outright by
web_radio_stream.cpp into main/esp32_i2s_sink.cpp, shared by both
producers with a simple tryAcquire()/release() exclusivity guard — web
radio streaming and a phone PCM stream would otherwise fight over the
same physical wire. web_radio_stream.cpp now acquires/releases around
each streamWhileEnabled() cycle instead of owning the channel itself.
net::PhoneStreamSink is a plain function-pointer struct (not a class
hierarchy) threaded through NetBootstrap::start() -> SetupWebServer::start()
-> HttpRouteContext, so components/net stays free of I2S driver headers;
main/phone_stream.cpp supplies the concrete functions (bound to
esp32_i2s_sink) and does the int16->ADAU 32-bit-slot conversion, batched
per chunk rather than per sample for the same reason as the web radio
stutter fix (6974095/7e65394 lineage).
Verified by build only — not confirmed live yet (board disconnected this
session); the actual phone app that will exercise this endpoint doesn't
exist yet either.

New core::IDsp::writeRawParam(address, value) safeloads any named
Parameter RAM cell in the compiled SigmaStudio program (74 cells: mixer/
Beep1/PEQ coefficients/limiter thresholds/etc — the same set SigmaStudio's
own Remote Connection, components/net/SigmaStudioTcpServer, already has
full access to). Value is a plain SigmaStudio floating coefficient,
converted to ADAU 8.23 fixpoint via the existing core::floatToFixpoint823.
Adau1701ParamTable.hpp holds the name->address table extracted from
Firmware/ADAU1701-Firmware/DigiRadio_IC_1_PARAM.h; core::DspParamJson
handles the wire format without core/ depending on the adau1701 driver
(net/SetupWebServer.cpp bridges the two, consistent with how other
JSON DTOs are supplied their data by the net layer).
GET /api/dsp/params lists every cell (name + address) for discovery.
PUT /api/dsp/param {"name":...,"value":...} writes one. Deliberately no
domain validation, matching the trust level already implied by the
existing SigmaStudio TCP bridge being reachable on the same network.
HTTP routes were registered in the SetupWebServer.cpp change committed
alongside the FM band scan feature (3a10ed7).

New TunerService::scanFullFmBand(): tunes to the band bottom then seeks up
repeatedly (reusing the existing hardware-seek + RDS-name-poll machinery
from scanForStation()) until the sweep wraps back around, collecting every
station that clears the existing scan RSSI/SNR thresholds. Returns the
list without touching saved presets or leaving the tuner in any particular
place — callers decide what to do with the results.
New POST /api/tuner/scan/full endpoint (core::TunerFmScannedStation DTO,
serializeTunerFmBandScanJson). Blocks for the whole sweep like the existing
/api/tuner/scan.

readDabServiceData(): 6 of 7 response fields (dataSrc, serviceId,
componentId, byteCount, segmentIndex, segmentCount) read one byte too
early, using the old raw[4]=RESP4 convention instead of the correct
raw[5]=RESP4 (established elsewhere in this driver by getPartInfo() and
readDabDigRadStatus()'s own ficQuality/cnrDb fields). dataSrc landing on
the wrong byte meant the DAB dynamic label (PAD/now-playing text) check
(dataSrc == 2) could essentially never match — it has likely never worked.
Header buffer grown 24->25 bytes to fit the correctly-positioned last field.
fetchDabServiceList(): didn't match AN649 Table 14's "DAB/DMB Digital
Service List" layout at all — serviceCount read from the wrong byte, every
per-service field misaligned, componentId assumed 4 bytes wide (actually
2 per the spec), and only the first of a service's possibly-several
components was ever skipped past (desyncing every later entry). Rewrote
against the actual Table 14 field layout. Confirmed live yesterday this
was producing garbled service_id/component_id/label output
(component_id values decoding as literal ASCII spaces).

readFmRds(), readDabDigRadStatus()'s acquired field, and
readDabEventStatus() all read raw[4] expecting AN649's RESP4 field, but
this driver's own established convention (getPartInfo(), and the
already-correct ficQuality/cnrDb fields in readDabDigRadStatus() itself)
is raw[5]=RESP4 (raw[0]=SPI lead-in, raw[1..4]=STATUS0-3). This is why
DAB_GET_EVENT_STATUS's serviceListReady never set — it was reading
STATUS3's ERRNR bit instead of RESP4's SVRLISTINT bit, so
/api/tuner/services returned service_list_empty forever regardless of lock
quality. Fixed all four sites; readFmRds()'s fifoUsed/blockA-D were
consequently also off by one and fixed together with it.
Confirmed live: first DAB ensemble locks in this project's history (3 found
sweeping freq_index 0-35, fic_quality=100, best CNR 20 dB on index 23), and
/api/tuner/services now returns real entries instead of service_list_empty.
The service-list entry contents themselves are still garbled (a third,
separate bug in fetchDabServiceList()'s body parsing, documented but not
fixed this session — see docs/si4684-rf-investigation-report.md).

Two independent bugs silenced the digital audio path from Si4684 into the
ADAU1701 even after the FM/DAB tune fix produced a real RF lock:
1. Si4684Driver::configureAfterBoot() wrote PIN_CONFIG_ENABLE (0x0800) as
0x0003, enabling both I2SOUTEN and DACOUTEN. AN649: "only I2SOUTEN or
DACOUTEN can be enabled at a time. If both enabled, only analog audio
output is enabled" — the chip silently fell back to its unused analog
DAC output on every boot. Fixed to 0x8002 (I2SOUTEN + INTBOUTEN),
matching the value hitech95/si468x_dab_receiver's working ALSA codec
driver uses (SI468X_PROP_I2S_ENABLED); I2SOUTEN alone (0x0002) was not
sufficient on this hardware. Also fixed AUDIO_OUTPUT_CONFIG (0x0302),
which was being written with a stray I2S-enable bit that property does
not have (its only real field is bit0 MONO).
2. Even with the chip correctly outputting I2S, the ADAU1701 received only
static. Traced with SIGMA_WRITE_REGISTER_BLOCK live overrides of
SerialInputRegister (0x081F, baked into the compiled SigmaStudio export
at ILP=0/IBP=0): IBP=1 (input data clocked on the opposite BCLK edge)
produced real, recognizable music instead of static on a locked, strong
FM signal — first confirmed end-to-end audio in this project's history.
ILP=1 made it worse and was reverted; IBP=1 kept as a runtime override
in Adau1701Driver::boot().
Remaining noise on top of the music is attributed to antenna quality
(RSSI/SNR fluctuated significantly between retunes of the same station on
the current improvised antenna) — not yet confirmed with a proper antenna.

writeCommand() had no way to send a non-zero ARG1, since it always
hardcoded ARG1=0x00 before the caller's payload. Every command whose real
ARG1 needed to carry a flag (STCACK, INTACK, SERTYPE, DIGRAD/EVENT ack) or
whose payload needed to start at ARG1 instead of ARG2 was silently broken:
- seekFm(): SEEKUP/WRAP never reached the chip (always ARG2=0x00), so
hardware seek always searched down/no-wrap; masked by the existing
100 kHz software-step fallback in Si4684Tuner.
- startDabService()/stopDabService(): SERVICE_ID/COMPONENT_ID shifted one
byte right of their real ARG4-11 positions, with SERTYPE landing where
the spec requires a fixed 0x00.
- readDabServiceData(): same shift, plus STATUS_ONLY was bit3 (0x08)
instead of the correct bit4 (0x10).
- clearFmStc(), readFmRsq(), readFmRds(), fetchDabServiceList(),
readDabDigRadStatus(), readDabEventStatus(): these AN649 commands have
only ARG1 and no ARG2 at all, so the old two-argument writeCommand()
could never carry their ack/status flags — clearFmStc()'s STCACK never
fired in this driver's history (masked by FM_TUNE_FREQ/FM_SEEK_START
auto-clearing STC per their own spec).
writeCommand() gains a fourth parameter, arg1 (default 0x00, preserving
every already-correct call site); each caller above now passes its flag
through arg1 instead of the payload array.
Confirmed live: first locked:true and first genuine hardware seek (not
software-fallback) in this driver's history — 87.5 -> 98.3 MHz, RSSI +12
dBuV, SNR +14 dB.

writeCommand() always prepends a fixed ARG1=0x00 byte before the payload;
tuneFm()/tuneDab() built their argument arrays starting at what the author
believed was ARG1, so every byte landed one slot right of its real AN649
position and an extra unused byte was appended. The chip never received the
requested frequency. This is the root cause of the months-long total RF
blackout (RSQ frozen at all-zero on every frequency/ANTCAP value) previously
attributed to a QFN exposed-pad hardware defect — that hypothesis is now
overturned, confirmed live: RSSI/SNR now read real, frequency-dependent
values with zero STC timeouts after the fix.
Also make BT1035 boot failure non-fatal in HardwareBootstrap::boot() so a
companion-chip fault no longer halts the whole device (Si4684 tuning, web
UI, Wi-Fi already isolate BT1035 readiness via CompanionChipStatus).

Redundant AT+RESET sent right after the hardware RESET# pulse could interrupt
the module mid bring-up; boot-banner probe window (1500ms) was too short for

Si4684Driver::getPartInfo()/getSysState() existed but were never called, so
their byte-offset bugs never surfaced. Wired them into a boot-time diagnostic
log (part number, firmware revision, active image, streamed blob byte counts)
to check whether the loaded DAB/FM firmware images are genuine and intact, as
an alternative explanation to the QFN exposed-pad hardware hypothesis.
Fixed two rounds of off-by-one bugs found while doing this: the fields were
initially read one byte too far right (e.g. firmwareBuild was reading a flag
byte, not a version number); the first fix undershot in the other direction
by not accounting for readRaw()'s one-byte SPI lead-in before STATUS0 (already
documented and confirmed elsewhere in this file, in pollStc()) -- caught
because the "fixed" GET_SYS_STATE reported image=192 (0xC0), the exact
signature of STATUS3 with PUP_STATE=3 seen throughout this investigation.
All three response buffers were already sized for the lead-in byte, which
confirmed the correct fix.
Verdict, captured live: blob streamed bytes match local file sizes exactly (no
truncation), GET_SYS_STATE reports image=2 (DAB active, correct), GET_PART_INFO
reports part=4684 (matches expected Si4684 part number) with a plausible
firmware revision -- the loaded DAB firmware is genuine and intact. This closes
the last plausible firmware-side explanation for the FM/DAB no-lock symptom;
docs/si4684-rf-investigation-report.md and docs/TODO.md (P4/H5) updated with
the full record and verdict.
Also noted, not yet fixed: BT1035 AT-init now fails deterministically on every
boot (was a one-off earlier this session) -- see report's Open Items.

- Add docs/si4684-rf-investigation-report.md: full record of the FM/DAB no-lock
investigation (crystal, front-end matching, ANTCAP sweep, continuity, leading
EP solder-defect hypothesis, PCBWay report sent) plus the separate audio
profile NVS bug found and partially fixed this session.
- Fix sigma_i2c_write() (SigmaStudioFW.c): no retry on I2C failure meant a single
transient NACK anywhere in a long safeload burst (EQ apply = ~55 sequential
transactions) aborted the whole sequence. Added a 3-attempt retry.
- Add granular failure logging (AudioService::applyProfileToDsp/persistProfile,
Adau1701Driver::applyMixer/applyEq, NvsAudioProfileStore::saveProfile error
codes) to isolate the remaining NVS-side audio profile save failure.
- Si4684Driver::tuneFm gains an optional ANTCAP argument (default 0 = unchanged
auto-tune behavior) used during this session's front-end matching sweep.

Streaming (main feature this session):
- New WebRadioConfig/WebRadioJson core types, ISecureStore-backed persistence
- New webradio::WebRadioService (thread-safe live config) + GET/POST /api/streaming
- web_radio_stream task now runtime-toggleable (no reboot), no hardcoded URL
- Content-Type diagnostic: warns clearly when a URL is a webpage, not an audio stream
Boot cleanup:
- Removed boot-time auto FM/DAB tune, auto-beep, and the (now-concluded) Si4684
crystal IBIAS/CTUN empirical sweep from main.cpp — tuning/beep are on-demand
via the existing REST API only
Web UI:
- Modernized styling (cards, gradients, toggle switches, light/dark theme)
- New Stream tab wired to /api/streaming
Fixes found via real idf.py build (not just clangd):
- Restored wrongly-removed si4684/Si4684Tuner.hpp include in main.cpp
- Fixed MP3Decode() argument types in web_radio_stream.cpp (unsigned char**/int*)
Quality-gate fixes:
- Host-test stub headers (esp_log.h, freertos/*) so TunerService.cpp's
scanForStation logging/pacing compiles for station_service_test /
integration_service_test instead of running stale binaries
- Added WifiScanner and WebRadioService manual sections; filled in missing
Doxygen docs on BluetoothService, i2s_sdata_probe, test_firmware, Bt1035At
- Ignore clangd's .cache/ index directory
Also includes prior uncommitted work carried in the tree: Wi-Fi/Bluetooth
device scan REST API and UI (WifiScanner, BT scan), SigmaStudio TCP bridge,
and the current ADAU1701 SigmaStudio DSP program export.
