Getting started

Step 1: Install

Connect to your raspberry pi via ssh:

cd /home/pi
git clone https://github.com/BLeeEZ/rpi-kvm.git
cd rpi-kvm
sudo ./rpi-kvm.sh install

Step 2: Start the RPI-K(V)M service

sudo ./rpi-kvm.sh start

Step 3: Optional steps

a) Display status and additional information

RPI-K(V)M is running in a tmux session. To see the service logger messages:

sudo ./rpi-kvm.sh attach

b) Open the web interface

To see detailed bluetooth client information go the RPI-K(V)M web interface: http://raspberrypi:8080

Note: If the host name has been changed during inital Raspberry Pi setup the webserver is reachable at its new RPI-KVM host name or its IP address

c) Connect a HD44780 LCD display

Follow this wiring guide to display the bluetooth clients on a LCD display.
