Connecting Android and Arduino with BT shield(slave) problems..

Good day guys..

I'm currently trying to connect my arduino with my android Phone.. I am able to pair with my the Bluetooth shield (paired but not connected)..

The problem is I cannot connect with the BT shield every time I use any android applications..

I've used a lot of applications, like, AMARINO, BLUETOOTH CHAT, BLUETOOTH SPP, BLUE TERM, ARDUINO COMMANDER.. but I still get the same problem... when I try to connect.. It automatically unpairs with my BTshield and ask for the PIN code again and again..

my android phone's version 2.3.5..

has anybody encountered this problem?..

any help guys?.. please.. :frowning:

What sketch and which shield are you using?
