I want to buy this Bluetooth module http://www.ebay.in/itm/Arduino-Wireless-Bluetooth-Serial-TTL-Module-Slave-4Pin-Serial-Port-/281066304418?pt=LH_DefaultDomain_203&hash=item4170db73a2 . But I'm thinking of the security risks. Any one could connect to it if they know the default pin. Is there a way to change the default pin or do something to prevent other phones from connecting to it.
Thanks.
Yes there is using AT command 'AT+PINxxxx' where xxxx is the new pin

Thank you for the reply. I checked the Bluetooth module in dx.com sku:121326 and it is the same. I downloaded the data sheet and it indeed does have a pin change option.
