Anyway to connect a bluetooth device which have a blank pin?

[Android Central Question]

The Bluetooth stack requires you to type something in the pincode line to proceed. This becomes a problem when connecting devices which pincode is blank. Have there been found a way to connect such devices?

The device should allow you to connect without putting in a PIN. Alternatively, you could try a PIN of 0000 (4 zeros).
