sudo apt-get install ros-$ROS_DISTRO-respeaker-ros

Or you can also build from the source.

    mkdir -p ~/catkin_ws/src && ~/catkin_ws/src
    git clone https://github.com/jsk-ros-pkg/jsk_3rdparty.git
    cd ~/catkin_ws
    source /opt/ros/kinetic/setup.bash
    rosdep install --from-paths src -i -r -n -y
    catkin config --init
    catkin build respeaker_ros
    source ~/catkin_ws/devel/setup.bash

    roscd respeaker_ros
    sudo cp -f $(rospack find respeaker_ros)/config/60-respeaker.rules /etc/udev/rules.d/60-respeaker.rules
    sudo systemctl restart udev

And then re-connect the device.

    git clone https://github.com/respeaker/usb_4_mic_array.git
    cd usb_4_mic_array
    sudo python dfu.py --download 6_channels_firmware.bin  # The 6 channels version 

    roslaunch respeaker_ros respeaker.launch
    rostopic echo /sound_direction     # Result of DoA
    rostopic echo /sound_localization  # Result of DoA as Pose
    rostopic echo /is_speeching        # Result of VAD
    rostopic echo /audio               # Raw audio
    rostopic echo /speech_audio        # Audio data while speeching

You can also set various parameters via `dynamic_reconfigure`.

    sudo apt install ros-kinetic-rqt-reconfigure  # Install if not
    rosrun rqt_reconfigure rqt_reconfigure

To set LED color, publish desired color:

    rostopic pub /status_led std_msgs/ColorRGBA "r: 0.0
    g: 0.0
    b: 1.0
    a: 0.3"

    rosrun  respeaker_ros respeaker_gencfg.py
