Bluetooth Tip
Don't expect a Bluetooth mobile phone headset to work with a Bluetooth enabled music player - there are different Bluetooth "profiles" used for audio headsets and phone headsets. The use of Bluetooth profiles simplifies things for designers, but makes life a whole lot more complex for us consumers!
Set up pairing codes for your Bluetooth devices, these act like passwords so that only people you give the code to can connect to your device, setting your own Bluetooth Pairing code helps prevent the use of software such as Bloover form being used to read contact details and SMS messages fron your phone without your permission.
