Demo of Apple HomeKit accessory server library.

Usage

  1. Initialize and sync all submodules (recursively):
git submodule update --init --recursive

  1. Copy wifi.h.sample -> wifi.h and edit it with correct WiFi SSID and password.

  2. Install esp-open-sdk, build it with make toolchain esptool libhal STANDALONE=n, then edit your PATH and add the generated toolchain bin directory. The path will be something like /path/to/esp-open-sdk/xtensa-lx106-elf/bin. (Despite the similar name esp-open-sdk has different maintainers - but we think it's fantastic!)

  3. Install esptool.py and make it available on your PATH. If you used esp-open-sdk then this is done already.

  4. Checkout esp-open-rtos and set SDK_PATH environment variable pointing to it.

  5. Configure settings:

    1. If you use ESP8266 with 4MB of flash (32m bit), then you're fine. If you have 1MB chip, you need to set following environment variables:
    export FLASH_SIZE=8
export HOMEKIT_SPI_FLASH_BASE_ADDR=0x7a000
    1. If you're debugging stuff, or have troubles and want to file issue and attach log, please enable DEBUG output:
    export HOMEKIT_DEBUG=1

  6. Build example:

make -C examples/led all
  1. Set ESPPORT environment variable pointing to USB device your ESP8266 is attached to (assuming your device is at /dev/tty.SLAB_USBtoUART):
export ESPPORT=/dev/tty.SLAB_USBtoUART
  1. To prevent any effects from previous firmware (e.g. firmware crashing right at start), highly recommend to erase flash:
    make -C examples/led erase_flash
  1. Upload firmware to ESP:
    make -C examples/led test

or

    make -C examples/led flash
    make -C examples/led monitor

ESP32

  1. Initialize and sync all submodules (recursively):
git submodule update --init --recursive

  1. Copy wifi.h.sample -> wifi.h and edit it with correct WiFi SSID and password.

  2. Install esp-idf by following instructions on esp-idf project page. At the end you should have xtensa-esp32-elf toolchain in your path and IDF_PATH environment variable pointing to esp-idf directory.

  3. Configure project:

make -C examples/esp32/led menuconfig

There are many settings there, but at least you should configure "Serial flasher config -> Default serial port". Also, check "Components -> HomeKit" menu section.

  1. Build example:
make -C examples/esp32/led all
  1. To prevent any effects from previous firmware (e.g. firmware crashing right at start), highly recommend to erase flash:
    make -C examples/led erase_flash
  1. Upload firmware to ESP32:
    make -C examples/led flash
    make -C examples/led monitor
