If you submit a MATLAB® command from your device and receive no response, or if you receive an error message regarding the connector, see the following sections:
For additional assistance, contact MathWorks® Technical Support.
Is MATLAB (R2014a or later) currently running on your computer?
In your MATLAB desktop session, did you start
the connector software using the command
Can the connector use the specified port? The default
port is 31415. To check that the port is available, open a web browser
and navigate to
http://localhost:31415. If you
specified a different port number while installing the components,
or if the connector is using a port other than the default port, replace
the port number.
If the connector can use the port, a message appears in the browser window, such as:
Welcome to the connector service.
Otherwise, consider changing the port number. Valid values are from 1,024 through 65,535. For help selecting the port, contact your system administrator. For instructions on changing the port, see Start the Connector (MATLAB Mobile for Android).
Is a firewall or antivirus software blocking access
to the port? To test, open a web browser and navigate to
computerID is the DNS name or IP address
that you defined for the connection. If the test is successful, the
connector displays a message in the browser stating that the connector
is set up correctly. Otherwise, modify your firewall or antivirus
settings to allow use of the port. For help with these settings, contact
your system administrator.
Are your device and computer on the same network? MATLAB Mobile™ requires access to the same network as the computer running the desktop version of MATLAB. If your device is on a 3G or 4G network, use VPN to connect to your network.
Is a network firewall blocking access to your computer?
To test, open the Web browser on your device and navigate to
as described in Check Your Computer (MATLAB Mobile for Android).
If you cannot connect, work with your system administrator to update
the firewall settings.
In MATLAB Mobile, did you correctly specify the DNS name (or IP address), password, and port number for the current connection? For more information, see Find a Computer’s DNS Name or IP Address (MATLAB Mobile for Android) and Edit Connections on Your Device (MATLAB Mobile for Android).
If you use MATLAB on more than one computer, is your device attempting to connect to the correct computer? To switch to a different computer, tap the Menu button or the menu and tap Settings. Then, select the connection you want. For information on defining additional connections, see and Edit Connections on Your Device (MATLAB Mobile for Android).
