Hi, 

1. otbr-agent service is successfully running on raspberrypi. See below.

2. RCP Firmware successfully flashed on nRF52840 DK Board. See below:

3. We are not able to figure out next steps from the Documentation. Our objective is to form a Thread Network and run example "Lock" using Android Chiptool.

4. Our RCP Board(nRF52840 DK) is now connected to Raspberrypi and status check is as below:

5. I also refer to your webinar of October 15, 2021 https://webinars.nordicsemi.com/developing-matter-products-with-nrf-4. Video duration 21:50 to 23:07

FORM Open Thread network is failed.

Please help us resolve the issue. We know if once Open Thread Network is formed,  Android Chiptool will automatically identify the "Lock" device which is flashed on the other nRF52840 DK Board.

Regards.

Hi Jogen,

FORM Open Thread network is failed.

How does it failed? Did you try to form with the web UI?

There is no "lock" device you can test with the thread network directly.

Are you playing with Matter device? Apple Homekit and Google Smart Home already have support on Matter now, so you can use their infrastructure to do Matter device test directly.

Best regards,

Charlie

Hi,

"How does it failed? Did you try to form with the web UI?"

Yes. 

If I understand this correctly then if a thread network is formed with RaspberryPi + RCP(in this case nRF52840DK) I should be able to connect and play with any matter device by scanning its QR code and using either of these 3 a. Apple HomeKit b. Google Smart Home c. Android Chip Tool.(This tool currently provides functionality of only Lock and Dimmable Light.).

If above is true then I would like to form a Thread Network using RaspberryPi + RCP(in this case nRF52840DK). and connect a matter device. But I am stuck after running otbr-agent successfully. 

"Are you playing with Matter device? Apple Homekit and Google Smart Home already have support on Matter now, so you can use their infrastructure to do Matter device test directly."

Even to do the above I have to create a Thrread Border Router. Correct?? 

Regards.
