- Use the defined consts when creating attributes - Pass in the strlen and the max size of attribute when creating attribute - Allocate max-str-size plus the size for storing the string length when creating the attribute metadata

|
- An optional argument, `max_val_size`, has been introduced to the `esp_matter::attribute::create()` API.
|
|
This argument is utilized specifically when creating attributes of the char string and long char string data types
|
|
to specify the maximum supported value size of an attribute.
|
|
|
|

|
|
|
- `ot_storage` partition is no longer required for Thread devices as the mechanism for storing data related to the Thread network has been changed in the `openthread` component in ESP-IDF.

#### *Changed how attribute data is stored in NVS*
|
|
By default primitive data types are stored as blob and that consumes more space in NVS.
|
|
Added a configuration option (`CONFIG_ESP_MATTER_NVS_USE_COMPACT_ATTR_STORAGE`) which uses
|
|
the primitive data type specific NVS APIs to store the attribute. This saves space in NVS partition.
|
|
|
|
Newer developements shall enable option `ESP_MATTER_NVS_USE_COMPACT_ATTR_STORAGE` to save on NVS space.
|
|
All the examples have this option enabled.

|
|
- `tools/mfg_tool/mfg_tool.py` now uses `connectedhomeip/connectedhomeip/src/setup_payload/python/generate_setup_payload.py` instead of previously used compiled `chip-tool` binary executable which additionally depends on `python-stdnum` module.
|
|
- Reinstall dependencies to use `mfg_tool` by running the following commands -
|
|
```
|
|
source $IDF_PATH/export.sh
|
|
python3 -m pip install -r tools/mfg_tool/requirements.txt
|
|
```

API Change
|
|
|
|
```
|
|
esp_err_t esp_matter::identification::init(uint16_t endpoint_id, uint8_t identify_type,
|
|
uint8_t effect_identifier = EMBER_ZCL_IDENTIFY_EFFECT_IDENTIFIER_BLINK,
|
|
uint8_t effect_variant = EMBER_ZCL_IDENTIFY_EFFECT_VARIANT_DEFAULT);
|
|
```
|
|
|
|
- Above API now accepts the parameters for initial identification `effect_identifier` and `effect_variant`.
|
|
- If not used then default value will be used for initialization
|
|
|
|
```
|
|
typedef esp_err_t (*callback_t)(callback_type_t type, uint16_t endpoint_id, uint8_t effect_id, uint8_t effect_variant,
|
|
void *priv_data);
|
|
```
|
|
|
|
- Added additional parameter `effect_variant` in identification callback.
|
|
|
|
```
|
|
esp_matter::start(event_callback_t callback, intptr_t callback_arg = static_cast<intptr_t>(NULL))
|
|
```
|
|
|
|
- This API now accepts a parameter to pass additional data to the event callback. By default, the data is set to NULL in the API.
