What to do after entering IP and reloading? #24

Closed positron96 closed 6 years ago

positron96 commented 6 years ago

I entered IP address of the robot, went to Control tag, reloaded the page, but nothing changed.

rosbridge is running fine and other app (namely, this: http://labrom.eesc.usp.br/rosweb/) can connect to it with no problem.

Does this app connect to a robot from the server or from browser?

The ROS Control Center works from the browser, so it should connect easily in principle.

Are there any errors in the console output?

Nevermind, I figured out what the problem was. The page was loaded from HTTPS and chrome does not want to connect to unsecured servers from secured page. In chrome console there was:

DOMException: Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS. at Ros.connect (https://pantor.github.io/ros-control-center/assets/js/roslib.js:1562:26) at new Ros (https://pantor.github.io/ros-control-center/assets/js/roslib.js:1541:10) at ControlController.newRosConnection (https://pantor.github.io/ros-control-center/assets/js/roscc.js:103:13) at ControlController (https://pantor.github.io/ros-control-center/assets/js/roscc.js:33:10) at Object.invoke (https://pantor.github.io/ros-control-center/assets/js/vendor.js:6552:19) at $controllerInit (https://pantor.github.io/ros-control-center/assets/js/vendor.js:12415:34) at nodeLinkFn (https://pantor.github.io/ros-control-center/assets/js/vendor.js:11295:35) at https://pantor.github.io/ros-control-center/assets/js/vendor.js:11703:13 at processQueue (https://pantor.github.io/ros-control-center/assets/js/vendor.js:18381:37) at https://pantor.github.io/ros-control-center/assets/js/vendor.js:18425:27 (anonymous) @ vendor.js:16074 (anonymous) @ vendor.js:12557 (anonymous) @ vendor.js:11709 processQueue @ vendor.js:18381 (anonymous) @ vendor.js:18425 $digest @ vendor.js:19520 $apply @ vendor.js:19818 (anonymous) @ vendor.js:15808 defaultHandlerWrapper @ vendor.js:5283 eventHandler @ vendor.js:5271

I changed link from https:// to http:// and it worked. So, consider changing link in readme to unsecured veriant.

Are there any errors in the console output? doesn't it works without browser....? It is working fine with browser. But its not working locally. I need clarification for that. Can u give me reply as soon as possible.
