Thread, join network problem

Hello,

We are struggling with joining Thread network using thread router eligible device example application.

Thread is created on a border router (Mbed Nanostack  mbed 6LoWPAN Border Router HAT | Mbed ), thread end device is NXP KW41Z board. 

 

after starting thread shell and [thr join] it fails:

$ thr join
Joining network...
$
Joining a Thread network...
Join failed

 

after creating thread network on router eligible device and detaching from its own network we can join border router's network

 

$ thr join
Joining network...
$
Attached to network with PAN ID: 0x500
Requesting Global Address...

 

the only difference we see is attribute permitjoin sets to 1 after creating its own network

$ thr get permitjoin
permitjoin: 1

 

Why is the behavior of router eligible device like that? Maybe we are doing something wrong?
Thank you for help!
