Support: OS Releases
M300 OS Announcements
Jun 26, 2017 | 1.2 The release of our most recent OS Version for the M300 brings with it a number of critical improvements we have been working on for some time, as well as some important bugfixes. The most significant component of this release is an upgraded audio subsystem which includes major improvements to the audio functionality of the M300. Improved Noise Cancellation - This will dramatically improve the usability of the M300 in noisy environments, including more reliable voice command recognition, as well as much clearer audio for communication purposes. Dual Audio Paths - This upgraded subsystem includes the addition of a dual audio path solution which will allow for simultaneous use of our voice recognition engine while also streaming or recording audio. These dual audio paths are filtered with different algorithms, one intended for human consumption with streaming audio use cases, and the other intended for machine processing for voice recognition. Applications will be able to leverage both of these audio streams, but the secondary stream will be leveraged by our voice recongnition engine by default. Another significant change to note is a change we have made to the behavior of the touchpad on the M300. The default behavior of the touchpad will now leverage douple taps for the select gesture, in place of the single tap gesuture previous used. This will all but eliminate the problem of unintended tap input, and allow us to pursue additional modifications to the logic of the touchpad driver to improve the consistency and reliability of swipe gestures in future releases. Additional changes listed below. Fixed an issue which was causing a delay in readings from the orientation sensors. Fixed an issue where artifacting would occur in preview images from the camera under certain circumstances. Fixed an issue where under certain circumstances the M300 would erroneously flag highly filtered/secure networks as not having internet connectivity and thus not properly reconnect and resulting in repeated erroneous user notifications. Fixed an issue impacting the use of recent releases of the Vuforia and OpenCV engines. Fixed an issue where under certain circumstances the flashlight LED would stay on when device is powered off. Fixed an issue where under certain circumstances the M300 would not properly wake up from sleep, which would require a reboot of the device. Added button combination to boot the M300 into fastboot mode. Added support for buttons to navigate the UI in fastboot and bootloader modes. Added notification which will inform users when certain camera features have been disabled when the M300 is low on power. Enabled a new UI screen to inform the user of progress while updates are being applied during an OTA update.
