Dear All,

What is the basic logic for one end device to rejoin the network?

What kind of parameters are needed in this process.

I want to simulate this process by myself, but I do not get the whole logic for that.

Best Regards

When an end device loses connection with its parent node, it will enable orphan state and start to send beacon requests to find a new parent node to rejoin.

Can you plaese tell me which API I can follow? I just found bdb_rejoinNwk() in bdb.c, it turns out it is not work. Which part of beacon request of orphan state is there in the code?

Best Regards

It's in

if ( events & SAMPLEAPP_END_DEVICE_REJOIN_EVT )
{
bdb_ZedAttemptRecoverNwk();
return ( events ^ SAMPLEAPP_END_DEVICE_REJOIN_EVT );
}
