Installing a License Key

How to install a license key.

Motorcortex Libraries require a license key to run in a production environment. You can always run your Motorcortex application without a license key, but the program will exit after 30 minutes.

You can check if you have a valid license if you look at your Motorcortex application log with the following command:

head -n 9 /var/log/motorcortex/`ls -Art /var/log/motorcortex/| tail -n 1`

Generating a hardware key involves some manual steps:

  1. Generate a hardware key:

    /usr/local/bin/{application} -k
  2. This will return:

    Hardware key: 8336911672998402376
    List of components: mcx-core2 mcx-io2 mcx-math2 mcx-control2 mcx-generic-app2 
  3. Email this hardware key and list of components to

  4. If you have purchased a license for the required components you will receive a license.pem file.

  5. Copy the license.pem file to the controller into the folder /etc/motorcortex/config/

  6. Restart the application and check the log file again.
