Connecting to the Raspberry Pi

Updating Raspberry Pi:

apt-get update && apt-get upgrade -y

• For bluetooth controllers:

  sudo bluetoothctl
  power on
  agent on
  default-agent

  The bluetoothctl will keep the bluetooth device talking to Linux.

  scan on

  This gives a list of the avaiable devices

  pair XX:XX:XX:XX:XX:XX

  This is the format for pairing the device with the device ID.

• For USB Controllers:
  Just plug in the USB cable

Communication

Turn off/unplug the device and use

ls /dev/input

Then reconnect/plug the device back in and run the command again. This gives the new device that is being added. For eg, Device1
Now to test out out the incoming data from the device:

cat /dev/input/Device1

if this gives an output it means the device is connected and it is communicating with the Raspberry Pi.
