The iOS connect path uses an encrypted characteristic to trigger the pairing dialog. Previously it only tried the partial flashing characteristic, which fails on devices without PF support. Now tries PF notifications, then Secure DFU buttonless notifications (V2), then DFU control read (V1). Each failure is instant (local GATT cache lookup) so there is no meaningful delay from retries.
