Paired BT devices switch between Linux and android

Hello,

We are using CC2564B 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 use opensynergy BT stack.

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

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

It seems link key copied from Android can't be used under linux.

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

Thanks.

Regards

Gao Hong
