Can I use a HomePod mini as a Thread bridge? And an iOS device or macOS computer to go with it?

Any examples?

Thank You very much for the post. With help of your guide, I could setup basic I am facing one issue while sending commands from my Android ChipTool application.

1/ otbr is successfully set, IPV6 address is assigned
sudo docker network inspect otbr | grep IPv6Address
"IPv6Address": "2001:db8:1::2/64"

2/ RCP device is successfully setup up on nrf5240 dongle

3/ door lock (on nrf 52840 DK H/W) got successfully provisioned and got IPV6 address

IPV6 address: fd11:22::7049:5794:aaf6:2379/64

6/ In Control window (On/Toggle/Off) in chiptool, I can see correct ipv6 address of the provisioned door lock thread device.

7/ When trying to send command (Toggle/Off etc), i am getting following error

chip.devicecontroller.ChipDeviceControllerException: OS Error 2101 (0x00000835): Network is unreachable.

Please suggest what could be the issue and remedy. Thank You

Hi all,

I use CHIPTool to scan the QR image but CHIPTool always displays "Scanning for BLE device 0" and then "Device not found".

Could you show me where should I concentrate to debug this?

Is the number 0 in "Scanning for BLE device 0" normal?

My phone's bluetooth can detect "ChipLock" is advertising.

Thank you very much.
