2018-12-05 07:06:46 -0500 | marked best answer | Issue with multiple instances of ublox_gps nodes Hello all, I have two ublox GPS modules and I want to connect and record data from both of them simultaneously into a rosbag.
I followed this suggestion and created a launch file as given below. It creates two different nodes _gps1_ and _gps2_. But topics are only published in one of them. What could be the error? I highly appreciate any suggestions. <launch>
<arg name="output" default="screen" />
<arg name="respawn" default="true" />
<arg name="respawn_delay" default="30" />
<arg name="clear_params" default="true" />
<node pkg="ublox_gps" type="ublox_gps" name="gps1"
output="$(arg output)"
clear_params="$(arg clear_params)"
respawn="$(arg respawn)"
respawn_delay="$(arg respawn_delay)">
<rosparam command="load"
file="$(find ublox_gps)/config/gps1.yaml" />
</node>
<node pkg="ublox_gps" type="ublox_gps" name="gps2"
output="$(arg output)"
clear_params="$(arg clear_params)"
respawn="$(arg respawn)"
respawn_delay="$(arg respawn_delay)">
<rosparam command="load"
file="$(find ublox_gps)/config/gps2.yaml" />
</node>
</launch>
Thank you Edit: Roslaunch output SUMMARY
