iPad cannot see BlueDuino rev2's Bluetooth

I have a BlueDuino rev2. I tried to connect to my iPads. Both of them can’t see my ZeroBeacon.
However, my Andriod phone can see it. Any idea?
I bought my brand new ipad mini 2 for my project with this BlueDuino…


Seems we have replied you by email.

yeah… but I still need help as both of my Andriod phone and iPad cannot connect to my ZeroBeacon…
