Switch Options (Internal and External)
The Blue2 has two built-in switches, one white and one orange. These switches can be used to active two independent functions in any of the six available modes. You may also opt to connect an alternative switch to the Blue2. This can be done by using either (or both) of the 3.5mm connections on the back of the Blue2.

Please note: any switch that is connect to the Blue2 will emulate the same function as the built-in switches. They cannot be assigned independent functions.

Pairing Details
Pairing Methodology
The Blue2 can be paired with any Bluetooth-enabled iOS, Android, Mac, Windows, or Chrome device. Functionality may be limited depending on the device you are pairing with the Blue2. The Blue2 is designed to be “seen” by other devices like a Bluetooth keyboard, therefore the information transmitted from the Blue2 to a device is a keyboard keystroke. For example, Mode 1 of the Blue2 sends a “space bar” when pressing the white switch (or switch labeled S1) and “enter key” for the orange switch (or S2).

Pairing with a Device

  1. Turn Blue2 on using the on/off switch.
  2. Press the pairing button on Blue2 one time.
  3. In your devices Bluetooth® settings find and select BLUE2.
  4. Repeatedly tap the mode button on Blue2 to select a mode.
  5. Set up any settings for your chosen method of switch access within the app or through accessibility options on the device you paired with Blue2.
  6. Blue2 is now ready for use with your device and/or app.
Configuring Blue2 with iOS & MacOS Switch Control
Blue2 can be paired to any iOS or MacOS device to be used for the accessibility option called “Switch Control”. Switch Control is a powerful accessibility option that allows a user to quickly and effectively navigate their iOS or MacOS device by use of our Blue2. For further information please review our iOS 13 Switch Control User Guide.

Configuring Blue2 with Android Accessibility

Configure Blue2 with an App
There are many applications in the marketplace for all of the supported hardware types of the Blue2. We recommend finding an application that will work with keyboard keystrokes (see "Pairing Details" section for additional information). Most apps built with accessibility in mind are very intuitive in terms of setup, but if you find an app that you like, we recommend accessing the user's manual for accessibility for details on available features and options within the app.

When paring my device to an iPad, iPhone, or other Apple device, why am I seeing a message stating “Using this accessory may affect Wi-Fi and Bluetooth connectivity”?
Information provided by Apple (as of iOS 13.4 and iPadOS 13.4) states that the message is to inform consumers of possible performance issues that could impact the functionality of their device by having too many unused Bluetooth device actively paired at the same time. Their recommendation to reduce the wireless connection impact is to disconnect unused Bluetooth devices that are not actively in use.

This can be done by going into Settings -> Bluetooth, tap the blue information button next to the accessory's name, then tap Disconnect or Forget.

We fully test our devices to ensure proper performance with Apple devices running the latest iOS or iPadOS operating systems to confirm compatibility.
