Ryan Malloy	ea22f2f9db	Fix async/await bugs found by headless E2E test - Make get_client() sync (was async but did no async work). Callers that omitted await silently got a coroutine object instead of the SerialClient, causing "'coroutine' object has no attribute 'connect'" errors on every tool call. - Fix esp32_connect: use get_client_or_none() for init check and client.event_queue.wait_for() for boot event (wait_event() didn't exist on SerialClient). - Normalise Response.data to dict at parse time — firmware returns bare strings on some error paths, which broke .get() calls in tool error handlers. - Remove stale await from ble.py (9 calls) and classic.py (4 calls). Tested with dual-MCP headless claude session: 26/27 PASS.	2026-02-02 15:54:36 -07:00

Fix async/await bugs found by headless E2E test

- Make get_client() sync (was async but did no async work). Callers
  that omitted await silently got a coroutine object instead of the
  SerialClient, causing "'coroutine' object has no attribute 'connect'"
  errors on every tool call.

- Fix esp32_connect: use get_client_or_none() for init check and
  client.event_queue.wait_for() for boot event (wait_event() didn't
  exist on SerialClient).

- Normalise Response.data to dict at parse time — firmware returns
  bare strings on some error paths, which broke .get() calls in tool
  error handlers.

- Remove stale await from ble.py (9 calls) and classic.py (4 calls).

Tested with dual-MCP headless claude session: 26/27 PASS.

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)
