- 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.
