How to keep paired BT handset connected after transfer between systems

Other Parts Discussed in Thread: CC2564C

Hello,

We are using CC2564C chip in our phone, our phone support Linux mode and Android mode both.

 After paired a BT handset with the phone under android mode which use bluedroid stack, we switch our phone to Linux mode which uses Opensynergy BT stack.

We also transferred the paired device information(mac address, link key), but after we start in Linux mode, the paired BT device under Android can't be connected under Linux mode.

We do the opposite way, and it still can't be connected.

It reports "AUTHENTICATED Auth Failure" and "LINK_DISCONNECT Conn Term User Req".

It seems link key copied from one system can't be used with another.

Is it possible to do such transfer work between different systems? What should do to enable such use case?

The failed connect log is attached.
