Troubleshooting

Device is not visible

If you don't see all of the devices that you expect to see, follow these steps:

  • Make sure that you are connected to the Internet, so that Windows can download the necessary drivers

  • Disconnect the device from the computer and then re-connect it

  • Click the "Scan for Devices" link in the bottom-right corner of the Hardware tab

If that doesn't work, follow the steps for the type of device that is missing.

Control Hubs connected via USB

  • Make sure that the Control Hub is plugged in via USB-C, not Mini USB

  • Make sure the Control Hub has had a chance to finish starting up, and that its light is green

  • Unplug the Control Hub from the computer and plug it back in

Control Hubs connected via WiFi

  • Make sure that the Control Hub is running version 5.5 or later of the Robot Controller app

  • Make sure the Control Hub has had a chance to finish starting up, and that its light is green

  • Make sure that you are currently connected to the Control Hub's WiFi network

  • Try rebooting the Control Hub. Re-connect to its WiFi network after its light turns green

  • Plug the Control Hub in via USB instead

Expansion Hubs connected to a Control Hub

  • Make sure that the Expansion Hub is in the active configuration file

  • Make sure that the Control Hub is running version 5.5 or later of the Robot Controller app

Android phones

  • Make sure that USB debugging is enabled in the Developer Options

    • If you can't find Developer Options anywhere in the Settings app (it may be listed on a System screen or similar), make sure it is enabled by tapping on the Build number 7 times on the About screen of the Settings app.

  • Unplug the phone from the computer and plug it back in. Look for a prompt to allow USB debugging, and click OK when it comes up.

  • Make sure that the ADB driver for your Android phone is installed. For Motorola phones, do this by installing Motorola Device Manager.

SPARK MAX Motor Controller

  • Make sure that the SPARK MAX is not being used by another application, such as the REV SPARK MAX Client
