3.8.5 How to register an ESP Matter product?
• To register a Matter product requires a CSA membership. After the product passes the Matter certification
test, it can be registered with the CSA.
3.8.6 When using Ubuntu virtual machine to develop ESP Matter on ESP32-C3, network
provisioning failed when I followed the Matter official tutorial. What could be the
reason?
It is not recommended to use a virtual machine for ESP Matter development, as the Matter Controller will
use Bluetooth hardware where unknown errors may occur with the virtual machine. It is recommended
to use Ubuntu 20.04 LTS and above hosts directly.
3.8.7 How to apply for a Matter DAC?
There are three ways to apply for a Matter DAC:
• Cooperate with an established PKI provider: Many organizations already have a certificate author-
ity that they rely on to obtain their public key infrastructure certificates. In some cases, a Device
Attestation Certificate (DAC) can be obtained from such a PKI provider.
• Use your own PKI: Many organizations already have public key infrastructures for code signing,
existing device authentication requirements, or other tasks that rely on asymmetric encryption. And
public keys are distributed via digital certificates.
• Cooperate with your platform vendor (Espressif): The platform vendor may embed a DAC
in a chip or platform module using their VID/PID. CD is used to remap VID/PID using the
dac_origin_vid/dac_origin_pid fields.
3.8.8 Does ESP Matter have a test tool/test app?
• Yes, it is recommended to use chip-tool. You can also refer to
3.8.9 Matter needs to use DCL in the network provision process. What is the specific
function of DCL?
• Matter DCL is a secure and encrypted distributed storage network based on blockchain technology, which
allows the Connection Standards Alliance (CSA) and authorized suppliers to publish their Matter device in-
formation. It also allows the Matter ecosystem to query related information through DCL clients.
• For simplicity, Matter DCL will be used for device verification and OTA.
3.8.10 How to connect our Zigbee-based products with Matter through ESP chip?
• The device based on ZigBee technology is not a Matter standard device. At this time, you need to bridge the
ZigBee device through the Matter Bridge device to access the Matter network.
• Matter Bridge devices can be implemented using an Espressif Wi-Fi chip + 802.15.4 chip. Matter Bridge For
BLE Mesh devices can be implemented with one Espressif Wi-Fi chip + BLE chip, or only one Wi-Fi + BLE
combo chip.
