Hi guys, I got vectornav vn200, and I have followed exactly this tutorial : https://github.com/dawonn/vectornav When I write "roslaunch vectornav vn200.launch", I get an error:

Error i saying

Could not set BinaryResponseListener output on device via: /dev/ttyUSB0, Error Text: Unknown Error

Here is my launch file content:

<launch>

    <node pkg="vectornav" type="vn200_node" name="vectornav"  output="screen" > 

      <param name="serial_port" type="string" value="/dev/ttyUSB0" />
      <param name="serial_baud" type="int"    value="115200" />

      <param name="binary_data_output_port" type="int"    value="2" />
      <param name="binary_gps_data_output_rate" type="int"    value="4" />
      <param name="binary_ins_data_output_rate" type="int"    value="20" />
      <param name="binary_imu_data_output_rate" type="int"    value="100" />

      <!-- Type: 0 None (Polling method), 19 IMU, 20 GPS, 22 INS -->
      <param name="async_output_type" type="int"    value="0" />
      <param name="async_output_rate" type="int"    value="100" />

      <param name="imu/frame_id" type="string" value="LLA" />
      <param name="gps/frame_id" type="string" value="LLA" />
    </node> 

</launch>

Before it was connected to /dev/ttyTHS0, I was getting error ls: cannot access /dev/ttyTHS0: No such file or directory, however i changed it to dev/ttyUSB0 and it is fine.

Check the owner and group of /dev/ttyUSB0. and try sudo chown quuser /dev/ttyUSB0.


EDIT

You can use the cutecom which is a serial port monitor to open /dev/ttyUSB0, and read data from your device.

You can install it by typing sudo apt-get install cutecom.

If cutecom can read your data, then you can say that your device works fine and there is something wrong with your ROS node program or launch file.

Yes, cutecom can read the data from Vectornav device and I am getting them properly.

So, what do you really suggest ?

I don't know the details, I think maybe your param in the launch file is not right, or maybe you have to debug your vn200_node program.

I am just a newbie, could you please let me know how to debug vn200_node file

you can use GDB or print some debug infomation. First of all you have to make sure vn200_node can open your device and get the data.

well, I checked content of my launch file, and as you said there were some problem with parameters, it was not matching with vn200_node.

Thank you for your kind help Shay : )
