It is often useful to know the Bluetooth MAC address of a smartphone from another device such as a personnal computer.
This page is a demonstration using a QR-code to make a logical link between the main device (e.g. a computer) and the targetted handheld device (e.g. mobile telephone) on which a mini Java or Android program will be semi-automatically downloaded to read and return its Bluetooth MAC address.
Requirements: This page is meant to be seen from a computer or any Web client. The targetted handheld is typically a mobile phone, which must have an Internet connection, a camera, and is either able to run Java programs (J2ME with MIDP-1+/CLDC-1+/Bluetooth-JSR82), or is running Android 2.0+.
