1.   Release Overview

This Release Notes document is for the RealWear HMT-1 firmware release 11.0.0, a security patch release with additional feature updates.

The release is only applicable to the HMT-1 standard model.  Any HMT-1 ever sold by RealWear may update to this release (although earlier updates may need to be installed before 11.0.0 can be installed.)

1.1  Deliverables

2       Release Notes

2.1  Android Baseline Update to 2018

In order to fully support Android Enterprise at a system level, the core implementation of Android 8.1 has been updated from the 2016 firmware version to the 2018 firmware version.

Both HMT-1 and HMT-1Z1 will now share a common firmware source, allowing for faster software updates to both device lines.

2.2  Android Enterprise Support

2.2.1     Managed Device

HMT devices can now be owned and managed by a central administrator.

2.2.2     Light Touch Enrollment

User or Admin can perform a simple one-time scan of a QR code to completely provision an HMT for an enterprise network.

Note: every HMT must scan a code after updating to Release 11, whether that code is for an EMM or a simple setup code generated by https://realwear.setupmyhmt.com/configure or the RealWear Companion app (available on the Google Play store and the iTunes app store).

2.2.3     File Based Encryption (FBE)

HMT devices can be fully encrypted and require a user to enter a PIN to unlock. This also enables a secure platform for multiple users.

2.3  Translation Changes

2.3.1     Translation Updates

Translation improvements and corrections for Korean, Polish, Portuguese (Brazil), and Thai.

2.4  Advanced Noise Cancellation Option

2.4.1    Noise Cancellation Toggle Setting

An advanced version of noise cancellation can now be enabled in Android Settings (My Programs → Settings → RealWear → Audio: Noise Cancellation) that is allows for more precise speech recognition in high decibel environments. This is a Beta feature, so please try it out and send us your feedback.

3       Software Update Method (Download PDF)

Release 11 is currently available on new units purchased after February 4th or with direct assistance from our Support Team. The software upgrade is also available as an over-the-air (OTA) update by providing your device serial number(s) to support@realwear.com.

Over-The-Air Update Procedure

Release 11 is now available as an Over-The-Air (OTA) update. Due to the need to re-partition and overwrite core parts of the Android operating system, the update process is a multi-step procedure guided by an additional Upgrade Helper application. Once the upgrade process has been started, please only use the on-screen prompts and do not attempt to use the HMT in any other way until the process has been completed (end of Part 3 below).

The HMT device must be running version 10.5.0-04-C.HMT-1.G to be eligible for the Release 11 upgrade. If the HMT is using a lower version of the firmware you must install the available upgrades to reach version 10.5.0-04-C.HMT-1.G, using the method detailed in the Wireless Update support page.

Before Updating:

Backup all user created data (images, documents, video, etc.) to a location other than the HMT. UPGRADING WILL ERASE ALL DATA ON THE DEVICE.

• Ensure the HMT-1 is connected to a Wi-Fi network.  Do not move out of the Wi-Fi network while download in progress.
• Do not use any voice commands other than those indicated on screen and/or within these instructions.
• Ensure the device’s battery is fully charged.
• Configure the device to use Right Eye orientation (you may switch back to Left Eye orientation after the upgrade is complete. See Screen Orientation for configuration details.)
• If the HMT-1 device is connected to a computer, disconnect before updating.
• Install a microSD card with at least 1GB free space, formatted for Android. Follow the instructions provided in Installing a MicroSD Card and Setting Up and Using a MicroSD Card before starting the update to 11.0.0. This will be used for data backup in the upgrade process; backup can be skipped if no data needs to be saved.
• Application Auto-Updates: for any applications installed on your HMT that automatically check for software updates, either temporarily disable this check or ensure all available updates are installed before starting the HMT update to 11.0.0. If any of these applications produce notifications requiring user interaction during the HMT upgrade process, dismiss the notification (using the displayed voice prompts or with “NAVIGATE BACK” or “NAVIGATE HOME”) to continue the HMT upgrade process. Do Not install application updates during the HMT upgrade process as this could lead to system instability or lead to upgrade failure.
• Prepare a QR code for device configuration (either from the RealWear Companion app or your EMM) for scanning after the upgrade is complete. The HMT cannot be used until a QR code is scanned.

Part 1:

1. Go to “My Programs” → “Wireless Update” → “Check for updates”
2. Download the Firmware OTA package. The correct build number shown in the Wireless Update application should begin with “10.5.0-05-C.HMT-1.G”
3. The screen will show progress as it downloads the install package.
4. When the download has completed (signified by showing 100% progress), say “Install Now” to install the update immediately. “Install Later” will prompt you for a schedule to update in the future.
5. A warning will be displayed stating that the update will take a few minutes.  Say “OK” to allow the update to proceed.
6. A dialog window will track the install progress and the device will reboot.
7. On reboot, an Android system screen with a colored, moving ring will display with the text “Installing system updates” is shown. After these updates are complete the device will restart again.

Part 2:

1. Once the device is on the Home Screen again after rebooting, we recommend not using or interrupting the device until the upgrade process is complete. Wait until the full screen notification is displayed that offers a prompt to “Update Now”. Saying “Update Now” will begin the software update and take you into the next step. Do not exit this screen except by saying “Update Now”.
2. The device will automatically begin creating a backup of your apps and settings. Data targeted for backup includes: system and app settings and app files (*.apk) of installed apps, up to a maximum of 150 mb. The HMT will not be usable again until the end of Part 3.
   1. If you do not have enough space on the HMT to create a sufficient backup locally or on your microSD card or attached USB drive, a notification requesting more space via USB drive or microSD card will be shown. You may “Try again” after inserting a microSD card or USB drive, or you may “Continue without App Backup” to stop the backup attempt and proceed with the update process.

Part 3:

Warning: Do not manually power cycle or attempt to use the HMT during this section. Interference with the update process could leave your HMT unusable and require RealWear technical support to restore your device to a working state.

1. After the Backup process is complete or skipped, the next update immediately begins downloading and you can monitor the status with the displayed progress bar. If you encounter a “Download Failure” screen during the download, use the “Try Again” command to continue.
2. The HMT will install this update, tracking the progress in a dialog window, and reboot again.
3. A larger download will start automatically, then reboot once downloaded. This download can take 30 minutes or more, depending on network conditions.
4. The HMT will reboot again, and it may remain on an empty black screen for an extended period of time (not to exceed a few minutes). DO NOT power cycle or otherwise attempt to ‘recover’ the device – wait for the HMT to restart on its own. If the black screen persists and the device does not reboot, please contact your RealWear Solutions Engineer for assistance.
5. Another Android system “Installing system updates” progress screen will be displayed after the reboot. The HMT will restart again after these updates.
6. After rebooting, the backup will be restored to your device and the HMT will reboot again. This step will be shown even if you chose to “Continue without App Backup”.
7. Once rebooted this final time, the Configuration app will automatically load and wait for a QR code to scan and set up the device.
   1. Every HMT must scan a code after updating to Release 11, whether that code is for an EMM system or a simple setup code generated by https://realwear.setupmyhmt.com/configure or the RealWear Companion app (available on the Google Play store and the iTunes app store). Once scanned your setup is complete and you may again use the HMT.
8. Once a QR code is scanned, the update to Release 11 is complete.
