Hi to all, :slight_smile:

I need a bluetooth comunication between arduino and android smartphone.
But I find cards with maximum capacities of 10 meters (30ft).
I need to control my robot with android for a range of minimum 30 meters (90ft).
thank you for your help! 8)

The typical and popular HC-0x family are good for 10m in line-of-sight. There are others more powerful but I believe 100m maximum not minimum. Try roving network or bluesmirf.
