HC-05 with an Arduino


I am trying to connect my Arduino with a smartswatch (in the purpose to get some data from the swatch). I am using a HC-05 module, everything works fine, but when I am trying to get all Bluetooth devices (AT+INQ), the swatch does not appear (whereas my iPhone appears and the swatch appears in the Bluetooth devices list on my iPhone).

I missed something I think... Do you have an idea of the problem ?

Thanks !

Phones and smart watches tend to use BLE 4.0 (Bluetooth low energy), the HC series is Bluetooth 2.x compatible. The two don't talk.
