- Replaced component esp32_mbedtls with mbedtls from requirements - Enabled CONFIG_MBEDTLS_HKDF_C option in all the sdkconfig.defaults - Removed secure cert dac provider from here and using one in connectedhomeip repo - Enabled CONFIG_ESP_SECURE_CERT_DS_PERIPHERAL in sdkconfig.defaults.esp32h2
Generic Switch
This example creates a Generic Switch device using the ESP Matter data model. This example aims to demonstrate the use of Fixed Label Cluster and User Label Cluster which provide a feature for the device to tag an endpoint with zero or more read-only labels using nvs api and zero or more labels respectively.
Note:
In order to retrieve the label-list from the fixed-label cluster the two options:
CONFIG_ENABLE_ESP32_FACTORY_DATA_PROVIDER and CONFIG_ENABLE_ESP32_DEVICE_INFO_PROVIDER have been set through sdkcofig.defaults.
See the docs for more information about building and flashing the firmware.
1. Additional Environment Setup
The steps below should be followed in order to access the fixed-labels.
- If monitoring the device using
idf.py monitor,pressCtrl + ]to stop the process. - The following command must be executed to flash the mfg partition:
esptool.py -p [port-name] write_flash 0x10000 mfg_binaries/20202020_3841.bin
-
Execute the command
idf.py monitor -
Commission the device with
discriminator: 3841andpasscode: 20202020chip-tool pairing ble-wifi 0x7283 [ssid] [password] 20202020 3841 -
Alternatively, below QR Code or Manual pairing code can be used for commissioning
- Manualcode : 34970012334
- QRCode : MT:Y.K90CEK012Z.548G00
-
To read the fixed-labels, use chip-tool.
chip-tool fixedlabel read label-list 0x7283 1
The example command given below should be executed to write to the label-list of User Label Cluster.
chip-tool userlabel write label-list '[{"label":"room", "value":"bedroom 1"}, {"label":"orientation", "value":"east"}]' 0x7283 1
To read label-list of User Label Cluster execute the command given below.
chip-tool userlabel read label-list 0x7283 1
2. Post Commissioning Setup
This should be followed by: Commission the generic switch device
- Turn on chip-tool interactive mode.
./chip-tool interactive start - By default latching switch is enabled so subscribe to switch-latched event via chip-tool.
switch subscribe-event switch-latched <min-interval> <max-interval> <destination-id> <endpoint-id> Double press the boot buttonon device so that client will receive event after max-interval.
2.1 Latching switch
Following are latching switch events mapped with boot button on device.
Double Press----------->switch-latched
2.2 Momentary switch
Following are momentary switch events mapped with boot button on device.
Button Press Down----------->initial-pressedButton Press Up ( Release )----------->short-releaseButton Long Press ( 5 sec )----------->long-pressedButton Press Up ( Long Release )----------->long-releaseButton Press Repeat----------->multipress-ongoingButton Press Repeat Done----------->multipress-completed
3. Device Performance
3.1 Memory usage
The following is the Memory and Flash Usage.
Bootup== Device just finished booting up. Device is not commissionined or connected to wifi yet.After Commissioning== Device is conneted to wifi and is also commissioned and is rebooted.- device used: esp32c3_devkit_m
- tested on: 4881109 (2022-12-15)
| Bootup | After Commissioning | |
|---|---|---|
| Free Internal Memory | 94KB | 110KB |
Flash Usage: Firmware binary size: 1.24MB
This should give you a good idea about the amount of free memory that is available for you to run your application's code.
