fix(partition_table): Check partition size for type APP 
The size of partition of type APP should be multiple of 4 KB. Partition
generation tool now make this as a mandatory requirement. This is
minimum flash erase size. If the size of the APP type partition is not
aligned to 4 KB then the last erase operation could go beyond the allocated
partition and hence may fail. This issue would only be observed when the
firmware size grows very close to the allocated partition size, and hence
causing the OTA update to fail.

For already deployed devices on-field with the size of APP partition not
aligned to flash sector boundary, it is best to ensure that firmware
size always remains within the lower 4 KB boundary of the total
allocated space. While migrating to ESP-IDF 5.3 release, partition table
for an existing project can be adjusted accordingly for the build to
succeed.

Supported Targets ESP32-C6 ESP32-H2

Light Bulb Example

This test code shows how to configure Zigbee end device and use it as HA on/off light bulb.

The ESP Zigbee SDK provides more examples and tools for productization:

Hardware Required

  • One development board with ESP32-H2 SoC acting as Zigbee end device (loaded with HA_on_off_light example)
  • A USB cable for power supply and programming
  • Choose another ESP32-H2 as Zigbee coordinator (see HA_on_off_switch example)

Configure the project

Before project configuration and build, make sure to set the correct chip target using idf.py --preview set-target TARGET command.

Erase the NVRAM

Before flash it to the board, it is recommended to erase NVRAM if user doesn't want to keep the previous examples or other projects stored info using idf.py -p PORT erase-flash

Build and Flash

Build the project, flash it to the board, and start the monitor tool to view the serial output by running idf.py -p PORT flash monitor.

(To exit the serial monitor, type Ctrl-].)

Example Output

As you run the example, you will see the following log:

light bulb:

I (918) ESP_ZB_LIGHT: status: 255
I (901) ESP_ZB_LIGHT: Zigbee stack initialized
I (901) ESP_ZB_LIGHT: Start network steering
I (2611) ESP_ZB_LIGHT: Joined network successfully (Extended PAN ID: aa:98:48:01:a0:03:f7:84, PAN ID: 0x0e8b)
I (5651) ESP_ZB_LIGHT: on/off light set to 1
I (6631) ESP_ZB_LIGHT: on/off light set to 0
I (7331) ESP_ZB_LIGHT: on/off light set to 1
I (8251) ESP_ZB_LIGHT: on/off light set to 0
I (9111) ESP_ZB_LIGHT: on/off light set to 1
I (9671) ESP_ZB_LIGHT: on/off light set to 0

Light Control Functions

  • By toggling the switch button (BOOT) on the ESP32-H2 board loaded with the HA_on_off_switch example, the LED on this board loaded with HA_on_off_light example will be on and off.
