Overview

CM-QS600 supported features are operated using normal Android controls.
This page contains information about features and services, which are less straight-forward to operate, or are less widely known. Enabling platform features page may be considered complimentary developer insight to this page.

Operating instructions

Automatic suspend when inactive

By default, CM-QS600 is configured to stay awake while connected to the power supply.
In order to change this behaviour, proceed to Settings->Developer options, uncheck Stay awake ... while charging option to enable the device suspend state.

Networking

Normal Android behaviour is to prioritize network interfaces (in descend order):

  • Ethernet
  • WiFi
  • 3G

Whenever higher-priority network interface is available, the lower-priority interfaces will be torn down.

Cellular Modem

CM-QS600 Android supports Telit HE910-XX 3G modem (supplied optionally) out of the box.
In case Telit HE910-XX 3G modem is installed, it will be detected and started automatically, with no additional actions required.

Audio sink selection

CM-QS600 may use either HDMI or analog audio output device. Audio sink selection should be done with a designated application, e.g. SoundAbout, available via Google Play Store.

audio device sink name
HDMI Aux Digital (HDMI)
analog Wired Headphones

LVDS display

CM-QS600 Android kernel supports Chi Mei (N116B6-L02) LVDS display (not supplied).
In order to send video output to the LVDS display, add the following parameter to the kernel command line:
