Overview

Most 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.

Operating instructions

Automatic suspend when inactive

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

Start-up script

/system/etc/startup-svc.sh script is run upon system boot by Android init process with root permissions.
As system partition is mounted 'read-only', one should remount system 'rw', prior to attempting to edit the script.

Networking

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

  • Ethernet
  • Wi-Fi
  • 3G

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

(Optional) 3G Modem

In case Telit HE910-XX 3G modem is installed, it will be detected automatically, by start-up service, with no additional action required.
