> If a device is already bonded, the host should not allow the same device to pair again.  Currently, the host blindly proceeds with the pairing operation.  This should not be allowed because the second peer could be an imposter masquerading as the original.
> I propose the following behavior in such a scenario:
> # Host notifies application of the duplicate pairing attempt via the gap event callback.  The callback would specify a new event code that specifically indicates a duplicate pairing attempt.
> # The gap event callback would return an error code indicating which of the following behaviors to perform:
> ## Reject the pairing request.
> ## Delete the original bond and proceed with the pairing operation.
