Communication between devices in Matter is based on the Internet Protocol (IP). Consequently, the transmission protocols provided are also IP-based. Devices that are to comply with Matter use at least one of the following three options: Ethernet / LAN (IEEE 802.3) WiFi / WLAN (IEEE 802.11) Thread (IEEE 802.15.4) Bluetooth Low Energy (BLE) is also included as a fourth standard. Thanks to Bluetooth, a smartphone or tablet can establish the first wireless contact with a Matter device during installation. Then, it transmits the access data for the Wi-Fi via Bluetooth to the device so that it can log into the home network. This also works with Border Routers for a Thread network.
