Hi,

i'm using a RPI 3B and all is fine there, but, doesn't work on my pc, i'm sure Ip's are correct, but when i use

ROS_NAMESPACE=rtabmap rosrun rtabmap_ros rtabmapviz _subscribe_odom_info:=false _frame_id:=camera_link

this appear

[ INFO] [1507244874.796473950]: Starting node...
[ERROR] [1507245004.961140490]: [setParam] Failed to contact master at [172.17.0.1:11311].  Retrying...

the PC's ip


and the RPI's IP



what am i doing wrong? thanks.


in the RPI i use this commands:

$ export ROS_IP=172.17.0.1
$ roslaunch freenect_launch freenect.launch depth_registration:=true data_skip:=2
$ roslaunch rtabmap_ros rgbd_mapping.launch rtabmap_args:="--delete_db_on_start --Vis/MaxFeatures 500 --Mem/ImagePreDecimation 2 --Mem/ImagePostDecimation 2 --Kp/DetectorStrategy 6 --OdomF2M/MaxSize 1000 --Odom/ImageDecimation 2" rtabmapviz:=false

in PC this commands:

$ export ROS_MASTER_URI=http://172.17.0.1:11311/
$ export ROS_IP=192.168.1.2
$  ROS_NAMESPACE=rtabmap rosrun rtabmap_ros rtabmapviz _subscribe_odom_info:=false _frame_id:=camera_link
