Specifying a link key in android without pairing

I am trying to determine if there is a way in android to associate a specific link key with an existing instance of a remote Bluetooth device.

In fact, I want to create a connection with an undetectable Bluetooth device without going through a pairing or pairing procedure.

I can’t set the link key with the device in the standard pairing procedure, because I work with my own custom pairing mechanism. I would prefer to complete this task without using my own code, but if I need to, I will do it.
