Communication with Ros bridge fails with built game

[jeremyfix]

Unity Version : 2017.2.0f4
Platform : Linux Ubuntu 16.04

Below I describe an issue encountered when building the game and running the built game. This issue does not appear if the game is executed from the Unity Editor.

Building the application for Linux x86_64 works. Then running the application, the websocket client successfully gets connected to the rosbridge node but there appears to be no message transiting on the topics and a warning is raised by the rosbridge node :

[WARN] [1512640449.098013]: Inbound TCP/IP connection failed: connection from sender terminated before handshake header received. 0 bytes were received. Please check sender for additional details.

[MartinBischoff]

Please activate "Developmend Build" in the Build Settings, build and run the application again and then post the log file here.
Here is further info on Log Files and Build Settings.

[MartinBischoff]

Without knowing the details yet, I presume it is because of the limited platform support of websocket-sharp. This issue might be related to issue #21 .

Please check if the following changes in Player Settings/Other Settings/Configuration have an effect:

• switching API Compatibility Level from ".NET 2.0 Subset" to ".NET 2.0"
• switching Scripting Runtime Version from "Stable (.NET 3.5 Equivalent)" to "Experimental (.NET 4.6 Equivalent)"

I built a developpement build and below is the log. I do not really anything very informative from the log ..

Running the binary :

I will make a test following your suggestions in your second comment.

Good news, as you suggested :

• switching API Compatibility Level from ".NET 2.0 Subset" to ".NET 2.0"

solved the problem. Thank you !

Closes #25

thanks, I solved my problem.
