The MATLAB and Simulink hardware support packages for Raspberry Pi use an SSH connection to communicate with the hardware. This will work regardless of whether there is a wired or wireless connection.
To communicate with the Raspberry Pi over WiFi you will need:
- The Raspberry Pi must be connected to a wireless network that the computer running MATLAB can also access. The simplest way of acheiving this is to have both the device and the computer connected to the same wireless network.
- The IP address of the Raspberry Pi, see: http://uk.mathworks.com/help/supportpkg/raspberrypi/ug/get-the-ip-address-of-the-raspberry_pi-hardware.html
Verify that your network is correctly configured by pinging the IP address of the Raspberry Pi. In a Command Prompt (Windows) or terminal (Linux, Mac) run the command:
where RPI_IP is the IP address of the Raspberry Pi. If it is successful this should return a reply and time information, if not it reports that the request timed out.
Once you can successfully ping the Raspberry Pi, configure MATLAB or Simulink to use the correct IP address to communicate with the hardware:
MATLAB Support Package
When executing the RASPI command, specify the device's IP address, username and password:
Simulink Support Package
When using the "Run on Target Hardware" window to deploy your model, set the "Host name" field to the device's IP address, and the username and password fields to the username and password for your device:
Note that the Simulink package also supports standalone operation. This means that a connection is needed for installing the support package and deploying any models onto the Raspberry Pi, but it is possible to run the created code without any connection to Simulink once a model is deployed.
