> The BLE host needs a way to handle the case where a security store write fails because the maximum number of entries have already been written.  Currently, the host simply fails to persist the record and returns an error code.
> I propose the following behavior in such a scenario:
> # Host checks that there is sufficient storage for a bond before it starts a pairing operation.  Any currently-active pairing procedures should be included in the total number of bonds.
> # If there is insufficient space, host notifies application of the issue via a callback.
> # The callback would return an error code indicating which of the following behaviors to perform:
> ## Reject the pairing request.
> ## Proceed with the pairing operation (presumably the application would delete a security record to make room before returning from the callback).
