Intermittently Connected Device (ICD)

This example creates a Matter ICD device using the ESP Matter data model. Currently it is available for ESP32-H2 and ESP32-C6.

See the docs for more information about building and flashing the firmware.

1. Additional Environment Setup

No additional setup is required.

2. Post Commissioning Setup

No additional setup is required.

3. ICD configuration options

The ICD configuration parameters can be configured in menuconfig.

# Enable ICD server
CONFIG_ENABLE_ICD_SERVER=y
# ICD Active mode interval(ms)
CONFIG_ICD_ACTIVE_MODE_INTERVAL_MS=1000
# ICD Active mode threshold(ms)
CONFIG_ICD_ACTIVE_MODE_THRESHOLD_MS=1000
# ICD Idle mode interval(s)
CONFIG_ICD_IDLE_MODE_INTERVAL_SEC=60
# ICD Fast Poll interval(ms)
CONFIG_ICD_FAST_POLL_INTERVAL_MS=500
# ICD Slow Poll interval(ms)
CONFIG_ICD_SLOW_POLL_INTERVAL_MS=5000

4. Power usage

The power usage will be various for different configuration parameters of ICD server.

Below are example current wave figures for ESP32-H2 Devkit-C and ESP32-C6 Devkit-C. The ICD configurations and radio TX power are list in the table.

Parameter	Value
ICD Fast Polling Interval	500ms
ICD Slow Polling Interval	5000ms
ICD Active Mode Duration	1000ms
ICD Idle Mode Duration	60s
Radio TX Power	20dBm
