Managing the Control Hub's WiFi

The Control Hub creates a WiFi access point to connect a Driver Station device or laptop to the Control Hub for programming and operation. Settings for the Control Hub access point are managed through the Robot Controller Console or the User Button on the Control Hub.

Before making changes to the Control Hub's WiFi network checking what WiFi bands are supported by the devices being used is important to ensure they will work as expected. Below are the Android Devices that are officially supported:

The following page is split into two sections. The first will cover how to access the WiFi Settings through the Robot Controller Console. It is recommended to use the REV Hardware Client as it will allow the user to access the WiFi settings over a wired connection. The second will run through the steps for using the Control Hub's User Button to preform a WiFi reset or WiFi band change.

If you run into any problems trying to use the Hardware Client or when resetting the WiFi, please contact [email protected]

Using the Robot Controller Console

The Robot Controller Console gives access to the WiFi settings of the Control Hub. Below are the steps to access the Robot Controller Console through the REV Hardware Client and the Driver Station application for updating WiFi settings.

REV Hardware Client

The REV Hardware Client allows teams access to the Hub's WiFi Settings information through a wired connection. The information is visible through the main page of the Robot Control Console and updated through the Program and Manage tab.

Download the latest version of the REV Hardware Client and install on a Windows PC. Skip this step if completed already.

Steps

Power on the Control Hub, by plugging the 12V Slim Battery (REV-31-1302) into the XT30 connector labeled “BATTERY” on the Control Hub.

The Control Hub is ready to connect with a PC when the LED turns green. Note: the light blinks blue every ~5 seconds to indicate that the Control Hub is healthy.

Plug the Control Hub into the PC using a USB-A to USB-C Cable (REV-11-1232)

Startup the REV Hardware Client. Once the hub is fully connected it will show up on the front page of the UI under the Hardware Tab. Select the Control Hub.

After selecting the Connected Hardware the Update tab will pop up. Select the Program and Manage tab. This will take you to the Robot Controller Console build into the REV Hardware Client.

Once in the Robot Controller Console, there are two options.

If just the WiFi Access Point name and password need to be found, they can be seen on the main page of the Robot Controller Console.

If any of the WiFi Access Point information needs to be changed, select the menu button in the upper right-hand corner of the page, indicated in the image below.

When the menu opens, select Manage.

The Manage page is where the WiFi Access Point information for the Hub can be viewed and changed. In the image below, the Hub's Wifi name, password, band, and channel can be changed. Editing these settings can help when the Hub is not showing up as a potential connection point from a computer or Driver Station device.

Once changes have been made select Apply WiFi Settings.

Once updates are made to the network reconnection to the new WIFi network is needed. When accessing the REV Hardware Client via a USB connection the Control Hub will stay connected to the REV Hardware Client. Rescanning for devices is necessary for changes to show in the Hardware Client.

Driver Station Application

The Manage page of the Robot Controller Console can also be accessed via the Driver Station Application. This is helpful in event environments, where Field Technical Staff may request that you change WiFi bands or channels to mitigate disconnections.

Select the three horizontal dots in the upright corned of the Driver Station Application

In the drop down menu select Program & Manage.

Once in the Robot Controller Console, there are two options.

If just the WiFi Access Point name and password need to be found, they can be seen on the main page of the Robot Controller Console.

If any of the WiFi Access Point information needs to be changed, select the menu button in the upper right-hand corner of the page, indicated in the image below.

When the menu opens, select Manage.

The Manage page is where the WiFi Access Point information for the Hub can be viewed and changed. In the image below, the Hub's Wifi name, password, band, and channel can be changed.

Once changes have been made select Apply WiFi Settings.

You will need to reconnect to the new WIFi network after changing the name/and or password.

Using the User Button

The Control Hub has a user button underneath the LED on the right side of the device. This button allows for a WiFi reset or changing the WiFi band currently being used on the Control Hub.

WiFi Reset

If you are unable to connect to the Control Hub's Wifi after switching to the 5 GHz band, you can perform a WiFi factory reset. The WiFi network name and password will be reset to their default values, and the WiFi band will be set to 2.4 GHz. To perform a WiFi reset, please follow the steps below.

The WiFi reset can take several minutes to complete.
