Hi @gizemarik,
After setting the ROS Master URI you should be able to receive Tango data on your desktop (enable local master should not be checked). Your device should be in the same network as your desktop.
Here are some tutorials that could help:

Hi @fangxu622
It seems that TangoRosStreamer does not find the roscore. Did you start a roscore on your desktop?
The TangoRosStreamer app publishes Tango data to the ROS ecosystem, so you need ROS to be installed on your desktop, and a roscore should be running.
The other solution is to run the roscore on the phone by enabling a local master (see app settings).

@PerrineAguiar hi .now i'm have two questions~thanks your reply

first .i'm sure start a roscore in my desktop, and which address should be fill in the MASTER_URI of
the phone ,and fill 192.168.43.106/1/255 ,it's incorrect likely~,how solve this ,i want to run master in my desktop1

second. and run the roscore in the phone ,and in my desktop set export $ROS_MASTER_URI=192.168.43.1 $ROS_HOSTNAME=192.168.43.1 ,it run successfully,like this

and why the colorcamera gui display have other thing ,if i want save the color image raw.

Hi @fangxu622
The master URI to fill in the app should be of the following format: http://<ip_of_your_desktop>:11311.
Concerning the color image display, you are using a Camera display which means 3D objects (e.g. pointcloud) are projected in the image. If you want the color image only, you can use the Image display.

yes ，I ‘m sorry for making a spelling mistake. i fill app in http://192.168.43.106:11311., tango phone and desktop connect same network ,i want to make the desktop as a master,and i fill http://192.168.43.106:11311 in app . it's incorrect ...

you can see this .

I also cannot connect to the master URI of ros from the smartphone "Tango ROS Streamer" app.
roscore is launched on the laptop and I can successfully ping the laptop's local net IP from the phone terminal.

/!\ But on the computer, ufw is running. I had to explicitly allow for the port used by ROS.
Then, on the app, the ROS light went to green!
But the Tango light stays red...

I'm currently using melodic (1.14.3) on Ubuntu 18.04 64 bits.
