Detached Condition from Child in the OT Role

[eric-bj-kang]

Hello,

I know there are roles in the Openthread like as below.

• Disable / Detached / Child / Router / Leader

And I could find the child detache state in the below link.

• Detached and Leader Detached and Leader #7716
  . Detached and Leader #7716
  . Whenever Thread devices lose fail to maintain connectivity with their existing Thread partition,
  they will detach and start the attach procedure to look for neighboring devices.
  . A child detaches when it is not able to communicate with its parent.

I want to know the detailed condition for the detached role, and the source code location for that.
I'm using an OpenThread v1.1.

Best Regards,
Eric.

The Thread Specification provides all of the details.

For relevant source code, take a look at src/core/thread/mle.cpp
