I would like to communicate with the arduino mkr1000 board.

I tried to upload a Simulink model and the board is on COM4 as a Arduino MKR1000, while uploading the COM Port switching

to COM 3 as a Arduino MKRZERO bootloader. Simulink could find the board concerning the Portswitch.

At this situation (Arduino is on COM 3 as bootloader) nothing works, I have to use the Arduino IDE to get the Arduino MKR1000 back.

I tried also to set the driver like the error message.

Every time I have the following error:

The following error occurred during deployment to your hardware board: 
Could not automatically set the host COM port for your MKR1000 board. This may be due to a disconnected or unrecognized board. 
If the board is not connected to your host computer, connect it and let Windows install the board driver. 
If the board is connected, update the board driver. Open Windows Device Manager and locate the board either in Other Devices or in COM Ports. Right-click on the board and select 'Update Driver Software...' Next, select 'Browse my computer for driver software'. Specify the search location as C:\ProgramData\MATLAB\SupportPackages\R2018b\3P.instrset\arduinoide.instrset\arduino-1.8.1\drivers and click 'Next'. 
If Windows still cannot automatically set the COM port for your board, set it manually. In your model, click 'Simulation ', click 'Model Configuration Parameters'... In the dialog that opens, select the 'Hardware Implementation' pane, click 'Target hardware resources > Host-board connection', change 'Set host COM port' to 'Manually' and set the 'COM port number' to match the port number in Windows.

Try putting the Arduino in bootloader mode before downloading the Simulink model and also make Simulink automatically set COM port.

To put Arduino in bootloader mode, double press the RESET button on the Arduino.

To make Simulink automatically set COM port, Configuration Parameters > Hardware Implementation > Hardware board settings > Target hardware resources > Host board connection > Set COM port > Automatically.

Let us know if this does not resolve the issue.

Thank you for your fast reply.

That works fine, I could upload the Simulinkmodel with the Deploy-to-Hardware-Button.

If I put the Arduino in the bootloader mode and upload the model, the Arduino changes his COM Port and a simulation will not work because Matlab don´t know that the COM Port is switched.

Is there a way to simulate the model and control the Arduino over the serial Port?
