Get a mobile phone’s Bluetooth MAC address through 2D-barcodes

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+.

As I have removed Java from this server, I do not do dynamic signing anymore, and only one user at a time is possible.

Bluetooth MAC address reader

All the steps below are to be done on your mobile phone:

  1. From your mobile phone, take a photo of the 2D-barcode below, using a QR-code reader (such as i-nigma).
  2. Your mobile phone’s Web browser will then download the Java or Android program and return its Bluetooth address to this Web page, after accepting a number of confirmations on your mobile phone.
  3. For information, the program will display the Bluetooth MAC address on your Mobile phone.
  4. You can quit the program.
