Mantis™ Q40 & Chameleon™ 20 Release Notes

Version 1.1

Features

  • Added language support for French (France), French (Canadian), and German. This includes braille codes, system languages, and keyboard layouts. On startup of a new device or after a factory reset, users will need to choose which profile they want—either English, French (FR or CA), or German; the one they select will apply the code, translation, and keyboard changes. After that, changes can be made for each item separately, and custom profiles can be created.
    • Note that rebooting is required when modifying the system language or keyboard layout.
    • Changes to the new English International, French, and German keyboard layouts resulted in our having to replace the Alt key in all hotkeys with the Fn (function) key. When using the default English keyboard layout, both the Alt and Fn keys will work with those hotkeys.
  • Update Process Changes
    • Installation of updates is allowed only when the battery level is above 50% and the unit is connected to a charger.
    • When downloading updates, a progress indicator is displayed.
  • Bluetooth Improvements
    • Bluetooth manager stability is improved.
    • All connected devices are now presented in a single list, and first-letter navigation can be used to select a device.
    • Successful connection messages are now automatically dismissed.
    • When reconnecting a device, a disconnected notification is no longer displayed during the reconnection process.
  • In the Editor’s File menu, it is now possible to select a different encoding if some characters do not appear properly using your current encoding.

  • The User Guide has been updated on the device to reflect these changes.

Installing a Firmware Update

To install the new firmware on your Mantis or Chameleon, you can do so either over the air via a WIFI connection, or manually with a computer and thumb drive.

Downloading Over The Air:

The simplest way to update your Mantis or Chameleon is by connecting it to a personal WIFI connection.  To do this, turn on your mantis so that it is at the device’s home menu:

  1. Press space until you find “Settings” or just press S followed by enter.
  2. In the Settings menu press space repeatedly to find “WIFI” or type a W followed by enter.
  3. If you see that WIFI is set to “Off”, press enter to turn it on.
  4. Now with WIFI turned on, press space repeatedly to find the “New Connection” option and press enter.
  5. The first item you see is “Scan for SSID”, press enter here to scan for your network.
  6. You will see a “Loading” prompt followed by a list of networks. Press space repeatedly to your network’s name and press enter.
  7. When prompted for the network password, type it in and press enter.
  8. You will see a “Loading” prompt followed by a “Connection Successful” message, confirming you are now connected to your network.
  9. Shortly after connecting to your network you will receive a notification that a new update is available asking if you want to download and install. Press space to the Ok button and enter to start the process.
  10. Downloading will take a short amount of time and your device will restart. Note that your battery must be above 50% to install the update, or connected to power.
  11. Upon restarting, you will see the braille display represent a progress bar to show you the installation progress.
  12. Upon completion your device will power off. Power it back on and you will be running the latest Mantis or Chameleon firmware.

  1. Using a computer download the most recent braille reader firmware.
  2. Right click on the .zip file and extract it to your preferred location.
  3. Plug in a USB thumb drive to your computer and copy the downloaded .SWU firmware file to the root of your thumb drive. (Do not put the .SWU file in a folder on the thumb drive).
  4. With your Mantis or Chameleon turned on, connected to power, or above 50% battery, safely eject the thumb drive from your computer and plug it into the Mantis or Chameleon’s USB host port on the left side of the device, just in front of the power button.
  5. After a few seconds you will receive a prompt asking if you want to install a found firmware update. Press space to navigate to the OK option and press enter.
  6. Downloading will take a short amount of time and your device will restart.
  7. Upon restarting, you will see the braille display represent a progress bar to show you the installation progress.
  8. Upon completion your device will power off. Power it back on and you will be running the latest Mantis or Chameleon firmware.
