- Switch UART0 for protocol I/O (USB bridge), disable ESP-IDF console - Wire all 21 command handlers into dispatch table (was only 4) - Add configure command handler (name, io_cap, device_class) - Add bt_classic_is_enabled()/bt_ble_is_enabled() for live status - Fix cJSON_False misuse in get_status (type constant, not boolean) - Fix esp_bt_gap_set_cod() to use esp_bt_cod_t bitfield struct - Fix auth_cmpl.auth_mode → lk_type for ESP-IDF v5.3 - Replace deprecated esp_bt_dev_set_device_name with stack-specific API - Remove unused bytes_to_hex, obsolete kconfig symbols - Use large partition table (1.5MB) for dual-mode BT stack Verified on ESP32-D0WD-V3 rev 3.1, /dev/ttyUSB4, all commands tested.
