![]() MAC stands for Media Access Control, and each identifier is intended to be unique to a particular device. 3 Easy Ways to Find IP address in Linuxįrom Wikipedia, A MAC address is the unique identifier that is assigned by the manufacturer to a piece of network hardware (like a wireless card or an ethernet card).5 useful Linux network troubleshooting commands.This article is part of the following series. The output will display the MAC address for all the network interfaces.Type ifconfig -a or ip link show or cat /sys/class/net/*/address command.If you’re new to the world of Linux, you can refer to “ Mastering the Linux Command: A Beginner’s Guide.” This in-depth article will be your guiding light, providing you with the foundational knowledge and skills required to navigate and wield the Linux command line interface (CLI) effectively and with assurance. The following commands can get you the MAC address of your network interface in Linux. These commands are safe to run without changing anything. Here are some methods to get the MAC address. On my rpi4 I found after entering bluetoothctl you can type help and get a list of all commands that’ll solve the problems/options the OP went over.How to list MAC address on Linux is a commonly asked question during a Linux job interview. This dissapointed me a little bit, when I upgraded the Pi and had built in bluetooth I hoped to actually be able to use it with my other bluetooth devices and use it to share my media across devices wirelessly – even stream audio from another device…no such luck as yet! other than the basic things regarding connection to the device and showing limited info. ![]() > scan on (display address and info of nearby devices)įrom there I am completely limited – eg after pairing i can’t do anythin-else worthwhile from the terminal. > sudo bluetoothctl (enter bluetooth commandline) The basic commands for the built in Pi 3 (latest Raspbian that allows bluetooth interaction) are: I can get a connection and pair up with the device but from there I have very limited access from the terminal I have a bluetooth device(phone) that allows filesharing and full access, and I want to play around with the Pi, to pull audio files wirelessly to the Pi and maybe vice versa. I haven’t had a good look hence the reason I am here, I hoped to fins a full list of commands to interact with bluetooth – Not sure on the date of this, but I am not certain if this is correct for the newer versions of Raspbian – what I mean is that these commands look like they would be suitable for a Pi 2 with a Bluetooth USB chip, the format for the Built In bluetooth seems different. You will need to get the devices MAC address by using the List commandīluez-test-device disconnect xx:xx:xx:xx:xx:xxīluez-test-device remove xx:xx:xx:xx:xx:xx (This will appear to do nothing if there are no devices). To allow the connection to complete you need to also do the following step to allow a remote device to actually connect:ġ234 is the pairing code for it to use, but this will can be automatically overridden by a randomly selected code displayed on both devices You will now be able to search and find the RPi from other devices such as windows "Add A Device" (development tip – if you've previously connected you'll need to remove it from Windows Devices for it to be able to found it again by Add A Device) Sudo bluez-simple-agent hci0 xx:xx:xx:xx:xx:xx To then connect to one of the found devices you can use this: In these notes "xx:xx:xx:xx:xx:xx" means the MAC address of the remote bluetooth device
