Modulo HC05 and Bluetooth 4.2

Hello everyone,
I use an HC05 bluetooth-uart module to connect a Lenovo M10HD tablet to an arduino board.

I have a problem: the tablet cannot find the HC05 module ....

The lenovo uses a bluetooth 4.2 protocol ...

How can I solve it?

I tried with a samsung tab-a tablet and recognizes the HC05 module ...

Hi. Make the connections and power on the Bluetooth Module. If this is the first time you are using your Bluetooth Module, then the LED will blink rapidly. In order to pair the module with your phone, open Bluetooth Settings in your phone and connect to “HC-05” with pin “1234”. But if the Lenovo don't see the module i think that the problem is on the Tablet. I read something on Lenovo Official Forum about Bluetooth Version mismatch. Sorry.
