Add HFP (Hands-Free Profile) support
...
Implement HFP client (Hands-Free Unit role) for the ESP32 test harness:
Firmware:
- bt_hfp.c/h: Full HFP client with call control, audio, volume, DTMF,
voice recognition
- Enable HFP in sdkconfig.defaults with Wide Band Speech support
- Add HFP commands/events to protocol.h and cmd_dispatcher.c
Python MCP tools:
- 15 new tools: enable, connect, audio_connect, answer, reject, dial,
send_dtmf, volume, voice_recognition_start/stop, query_calls, status
- Full protocol constants in protocol.py
Tested: HFP enable returns role='hands_free_unit', ready for AG pairing

Add HID (Human Interface Device) profile support
...
Implements Classic Bluetooth HID Device profile for keyboard/mouse emulation:
Firmware:
- bt_hid.c/h: HID device driver with combo keyboard/mouse HID descriptor
- cmd_hid_{enable,disable,connect,disconnect}: HID lifecycle management
- cmd_hid_send_keyboard: Send keyboard reports (modifier + up to 6 keys)
- cmd_hid_send_mouse: Send mouse reports (buttons + relative X/Y)
- cmd_hid_status: Query HID state (enabled, registered, connected)
Python MCP tools:
- esp32_hid_enable/disable: Control HID device mode
- esp32_hid_connect/disconnect: Manage HID host connections
- esp32_hid_send_keyboard/send_mouse: Send HID reports
- esp32_hid_status: Get connection state
Config:
- Enable BT_HID_ENABLED + BT_HID_DEVICE_ENABLED in sdkconfig.defaults
- Add bt_hid.c to CMakeLists.txt
Tested E2E: Linux (hci1) connects to ESP32 HID device, keyboard and
mouse reports sent successfully.

ESP32 Bluetooth test harness MCP server
...
UART-controlled ESP32 peripheral for automated E2E Bluetooth testing.
Dual-mode (Classic BT + BLE) via Bluedroid on original ESP32.
Firmware (ESP-IDF v5.x, 2511 lines C):
- NDJSON protocol over UART1 (115200 baud)
- System commands: ping, reset, get_info, get_status
- Classic BT: GAP, SPP, all 4 SSP pairing modes
- BLE: GATTS, advertising, GATT service/characteristic management
- 6 device personas: headset, speaker, keyboard, sensor, phone, bare
- Event reporter: thread-safe async event queue to host
Python MCP server (FastMCP, 1626 lines):
- Async serial client with command/response correlation
- Event queue with wait_for pattern matching
- Tools: connection, configure, classic, ble, persona, events
- MCP resources: esp32://status, esp32://events, esp32://personas
Tests: 74 unit tests passing, 5 integration test stubs (skip without hardware)
