Android 6 and 7 (Nexus and Pixel recommended)

To start your Tecla Shield should be in Switch Access / Switch Control Mode (Blinking purplish white). If you are using wheelchair controls or a joystick to control your device, your Tecla Shield should be in Mouse Keys (blinking light blue or “aqua” colour). If you are not sure how to change modes check here: Mode Change Instructions

With the Tecla Shield ready for connection – the status indicator light should be blinking white and the switches should be connected to it - follow the steps below to set up your Android device with Switch Access.

1. Pair your Tecla Shield: Go to Settings > Bluetooth. With Bluetooth enabled, you should see the Tecla Shield DOS listed under Available devices as TeclaShieldDOS-XXXX (where XXXX is a random sequence). Click on it. After a few seconds, TeclaShieldDOS-XXXX should be under Paired Devices and appear as Connected

                                          

2. Set up a Smart Lock: Once the Tecla Shield is connected, you can set it as a trusted device. This will keep your device unlocked as long as the Tecla Shield is connected to it. You’ll see a lock icon in the notification bar. Click on it and follow the steps to set up your Tecla Shield as a trusted device.                          

 3. Assign your switches to Switch Access actions

a. Go to Settings > Accessibility, then select Switch Access. Click on Settings on the top right corner to go to Switch Access Preferences.  

     

b. If you are using single-switch access, select Enable Auto Scan. A Time Delay option will now be available to set the scanning rate (the default is one second). Next, go to Assign Keys for Scanning and select Auto Scan. When the Auto Scan pop-up window appears, press the switch and click OK.

    

c. If you are not using Auto Scan, go to Assign Keys for Scanning, select a scanning action (i.e. Select) and when the pop-up window appears, press the switch you want to assign to that function. You’ll need to assign a switch to Select and Next for step scanning. If you have more than two switches, you can assign other actions (like Home, Back or scrolling) to switches under Assign Keys to Actions.Check Available Actions later in this guide for a brief description of other possible switch actions that you can assign to switches. The Recommended Configurations (table 1) may also be helpful for assigning switch actions.

   

 4. Enable Switch Access: Go back to Switch Access, and activate Switch Access by clicking on the on/off control. At this point, you should be able to control the Android using the Switch Control through the Tecla Shield. When you pressed any of your assigned switches you should see a frame around the user interface.

   

5. Ensure On-Screen Keyboard is shown: The Tecla Shield is seen as a hardware keyboard by Android, you need to tell the system to show the on screen keyboard. Go to Language & input, select Current Keyboard and enable Show input method.
