Problems with creating thread networks with multiple OTBR

[taoyinzhou]

Hi All,

    I want to create a Thread network with multiple OTBRs, which is based on two nRF52840 run Thread RCP hex provided by Nordic SDK.

    I created the thread network by using the following command.

Then the second device uses the same command. Later, I noticed that the state of the second RCP OTBR was Child.

But I think there are some problems:

1. The second RCP's state is always Child and does not promote to Router automatically.
2. OTBRs can not ping each other's IPV6 address on the wpan0 interface.
3. The second RCP can changes into Leader from Child through the command: "state leader" and the first device is also shown as Leader. In this case, there are two leaders in one Thread network?

4. I want the second RCP to be the commissioner. But when I type in the command: "commissioner joiner add eui64 pskd", it warns "invaildState". Whether it cannot be the commissioner because it is in Child state?

Any help would be appreciated, thanks in advance.

Best,

Tao

The problem is solved.
