Please help me to retrieve the Bluetooth MAC Address of my Galaxy S3 phone connected via USB port. My device is rooted.

Answer 1

adb shell cat /sys/class/net/wlan0/address

Answer 2

Running netcfg will show you all interfaces on the system along with their MAC addresses.

Answer 3

Isn't bluetooth MAC address available on every Android phone in Settings?

Currently I have 2 devices near:

On Samsung Galaxy S2 - Settings > About Phone > Status

On HTC Desire - Settings > About Phone > Hardware Information

(Bluetooth must be turned on)

Answer 4

I usually get the mac address of the WiFi interface of an Android device (that is connected to my PC through a USB port) by running these commands:

1. Find the device name using:

   adb devices
   

   Results usually looks like:

   List of devices attached 
   4e7354af    device
   1f97033e    device
   

   In this case we have two devices connected 4e7354af and 1f97033e. Let's work on the first one: 4e7354af

2. Get the mac address for the first device:

   adb -s 4e7354af shell ip addr show wlan0  | grep 'link/ether '| cut -d' ' -f6
   

   In previous line, we used the -s option with the adb commands to specify the serial number. Then shell indicate that is a linux command followed by the ip addr show wlan0 | grep 'link/ether '| cut -d' ' -f6 this command can also be used in Linux if its interface has the same name as wlan0.

I generally use this approach because I have many devices connected to my testing environment. Good luck guys.
