## 2. Distinzione critica: BLE vs controllo
### Controllo dispositivo (tuner, audio, preset, BT config)
**Trasporto documentato:** HTTP JSON REST su **TCP porta 80** (WiFi).
- Setup mode: SoftAP `DigiRadio-<suffix>``http://192.168.4.1/`
- STA mode: stessa API su IP LAN o **mDNS** `digiradio-<suffix>.local`
- **NON esiste** un protocollo GATT proprietario documentato per tuner/audio/preset.
### BLE (ESP32-S3 onboard)
**Solo provisioning WiFi** in setup mode (`ch-api.tex` §BLE provisioning):
- Stack: ESP-IDF `wifi_provisioning` + `scheme_ble`
- Sicurezza: **Security1** (protocomm)
- **Proof of possession (PoP):** serial number dispositivo (stesso valore di `GET /api/health``serialNumber`)
- **Nome servizio BLE:** SSID SoftAP = `DigiRadio-<suffix>` (es. `DigiRadio-CC4DB4`)
- Su successo: credenziali salvate in NVS, reboot in STA
- **Non è un endpoint HTTP** — nessuna REST call
### Bluetooth Audio (streaming verso speaker esterno)
**Modulo separato FSC-BT1035** (classic BR/EDR A2DP), controllato dal firmware via **UART AT**, esposto all'app solo tramite **HTTP** `/api/bluetooth/*`.
L'iPhone **non** si collega in A2DP al DigiRadio per ascoltare: il DigiRadio invia audio al Bose/Speaker via BT1035.

## 3. Architettura hardware (sintesi)
```
Si4684 (SPI) ──I2S──► ADAU1701 (I2S master 48 kHz) ──I2S──► BT1035 ──A2DP──► Speaker
ESP32-S3 (WiFi/BLE, HTTP server, opz. I2S test)
```
Sorgenti audio nel DSP: **Si4684** (radio), **ESP32 I2S** (stream locale / phone push).

## 5. Funzionalità per schermata app
| Area | Supportato (documentato) | Note |
|------|--------------------------|------|
| Connessione WiFi | ✅ | BLE prov. + SoftAP + POST /api/wifi |
| FM tune/seek/scan | ✅ | RSSI, SNR, RDS PS/RT |

| AUX/USB come sorgente UI | ❌ | Non esposto in API |
| Notifiche push BLE stato | ❌ | Nessun GATT documentato |

## 6. Implicazioni per igiRadio
1. **DigiRadioService** → implementazione **HTTP REST** (URLSession), non GATT custom.
2. **BLE layer** → solo **WiFi provisioning** (ESP protocomm Security1 + PoP = serial).
3. **MockDigiRadioService** → stessa interfaccia, dati fittizi.
4. **Discovery** → mDNS `.local`, IP manuale, o join SoftAP in setup.
5. **Real-time** → polling selettivo su `/api/tuner/status` quando in radio; nessuna notifica BLE documentata.
---
## 7. UNKNOWN — specification required
| Voce | Motivo |
|------|--------|
| UUID GATT controllo tuner/audio | Non documentati — controllo è HTTP |
| Artwork/metadata streaming | Non in API tuner |
| Protocol version field | Solo `fw` in health |
| Hardware revision API | Solo `serialNumber` + chip flags |
