Now I use CHIP iOS Tool App, and comissioned sample accessory, but work onluy via Bluetooth. This is interesting because the official Bluetooth in Matter is only supposed to use for pairing, but not for data and commands transmision. However, the sample accessory and the test application for iOS from the official repo, communicates and cend command (on/off/toggle light) over Bluetooth what can be seen from the logs and disabled Thread network in the accessory.

I compiled and installed the sample accessory from connectedhomeip (nRF52840 board, Bluetooth & Thread). Unfortunately after putting the accessory into pairing mode, the Home app in iOS 15 and iPadOS 15 does not see the Matter accessory. I have two HomePod mini but with 14.6 OS. Other accessory center are iPad Air 2 witch iPadOS 15 and Apple TV HD witch tvOS 15. The accessory broadcasts correctly over Bluetooth and emits a pairing code over NFC, but iOS says the NFC code has no data. Does the first beta not support Matter yet?
