I have encountered this error repeatedly, without being able to find a solution at all.
The test app by MATLAB Connector works perfectly fine.
The applications i create are able to run when uploaded using "deploy to hardware"
However, when the play button is pressed, the following error is obtained, as a result, i cannot read my android's sensor data in my MATLAB PC.
Error occurred while executing External Mode MEX-file 'ext_comm': Failed to connect to the target. Possible reasons for the failure: a) The target is not switched on. b) The target is not connected to your host machine. c) The application for the model is not running on the target. You might have clicked the Stop button. If the Run button is not dimmed, click it. Otherwise, click the Build button, which downloads and runs your application on the target. Caused by: An error occurred attempting to open an rtIOStream. More detail may be reported in the MATLAB command window
Any help is greatly appreciated.
Thank you !
