Product details
Overview
HOMEKIT-SDK from NXP is a software development kit implementing the HomeKit Accessory Protocol (HAP) for ARM® Cortex®-M4-based Kinetis K host MCUs, with integrated Bluetooth Smart 4.1 (BLE) support via Kinetis KW30Z/KW40Z wireless MCUs, firmware update capability via iOS app, and conditional console debug over USB/UART - used in certified HomeKit accessory development.
For engineers reviewing the HOMEKIT-SDK datasheet, HOMEKIT-SDK pinout, HOMEKIT-SDK application, or HOMEKIT-SDK equivalent, this SDK enables rapid prototyping of Apple-certified smart home accessories on NXP Kinetis platforms with transport-agnostic APIs, built-in security primitives, and production-ready licensing.
Technical Context
The HOMEKIT-SDK implements the full HomeKit Accessory Protocol stack including Attribute Protocol, GATT, L2CAP, and HCI layers, with BLE 4.1 Link Layer and Host Stack integration targeting Kinetis KW30Z/KW40Z wireless MCUs. It supports dual-bank flash for secure OTA updates and leverages hardware RNG and MMCAU acceleration on Kinetis K-series hosts.
Code adaptors decouple user application logic from transport layer, enabling reuse across K11, K22, K24, K26, K64, and K66 host MCUs. Configuration structures, callback interfaces, and HAP binary generation are standardized - no direct register-level MCU interaction required by application developers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| HAP Compliance | Fully implements Apple-defined HomeKit Accessory Protocol v1.x for certification readiness |
| BLE Version | Bluetooth Smart 4.1 (BLE) - validated with KW30Z/KW40Z radio stacks, not BLE 5.x or mesh |
| Host CPU Support | Kinetis K11/K22/K24/K26/K64/K66 (ARM Cortex-M4F, 50–180 MHz) |
| Wireless MCU Support | Kinetis KW30Z (BLE-only) and KW40Z (BLE + 802.15.4) - verified FSCI interface |
| Firmware Update | iOS-initiated OTA via HAP-defined characteristic; requires dual-bank flash on host MCU |
| Debug Interface | Conditional "print to console" over USB CDC or UART - enabled/disabled at compile time |
| Licensing | Unlimited production license included; no per-unit royalty or runtime fee |

FAQ
Does HOMEKIT-SDK include production license rights for commercial deployment?
Yes. The HOMEKIT-SDK download includes an unlimited production license - no per-unit royalties, runtime fees, or additional licensing tiers are required for commercial deployment of certified accessories. This license covers all supported Kinetis host and wireless MCUs listed in the official release notes (HMKITSDKFS REV 1).
Which hardware development boards are officially supported with HOMEKIT-SDK?
HOMEKIT-SDK is validated on NXP Freedom development boards: FRDM-K22F, FRDM-K64F, FRDM-K66F, and FRDM-KW40Z. These boards provide the required Kinetis K-series host MCU and KW30Z/KW40Z wireless companion, with preconfigured UART/USB debug paths and dual-bank flash for OTA updates.
Is HOMEKIT-SDK compatible with non-NXP microcontrollers?
No. HOMEKIT-SDK is architecturally bound to NXP Kinetis K-series host MCUs (K11/K22/K24/K26/K64/K66) and Kinetis KW30Z/KW40Z wireless MCUs. Code adaptors exist only for NXP's FSCI and Kinetis SDK low-level drivers - no porting layer for third-party silicon is provided or supported.
Does HOMEKIT-SDK support IP-based transport (e.g., Wi-Fi or Ethernet)?
IP transport is explicitly listed as "Planned support" in the official documentation (HMKITSDKFS REV 1), but is not implemented in the current release. All production-ready functionality relies solely on BLE 4.1 over KW30Z/KW40Z - no Wi-Fi, Ethernet, or Matter/IP stack integration is included or functional.
What debug capabilities does HOMEKIT-SDK provide during development?
HOMEKIT-SDK includes a compile-time configurable "print to console" debug function routed over USB CDC or UART to Mac/PC. It outputs protocol state, HAP event traces, and error codes - disabled by default in production builds to minimize footprint and avoid security exposure in certified accessories.
