Wireless Manager

EMDK For Android - 6.7

Overview

The Wireless Manager (WirelessMgr) controls usage of all radios on the device, which varies by device and can include Bluetooth, GPS, NFC and WWAN radios. Through control of device radios, the WirelessMgr permits administrators to prevent device users from accessing any of a given radio's functions or those of the devices or networks they connect with, providing a measure of security that is impenetrable by the device user.

The WirelessMgr also can control the GPS Location Mode to help preserve battery life, and on some devices the state (active/inactive) of the Bluetooth radio.

It's important to distinguish between the terms "State" and "Usage." The State of a radio refers to whether that radio is turned on (and available for communication), or off (inactive). Usage determines whether that radio is enabled on the device. A radio's State can be controlled by the device user or administrator only if its Usage is Turned On (enabled).

Android devices often come with a variety of wireless communication interfaces. These include bidirectional interfaces such as Bluetooth, Wireless Wide Area Network (WWAN/cellular data), Near Field Communications (NFC) and the unidirectional (receive-only) Global Positioning System (GPS). Wireless radios that can transmit may significantly effect battery life if turned on unnecessarily. Some radios also might need to be turned off in certain situations, such as during air travel or when in hazardous environments.

Antenna Selection

Used to select between built-in and external antennas for Bluetooth and Wi-Fi (WLAN) communications on the device. This feature applies only to the Zebra VC80x and similarly equipped vehicle-mounted computers.

Parm Name: AntennaSelection

Option Name Description Requires
0 Do not change This value (or the absence of this parm from the XML) will cause no change to settings; any previously selected setting will be retained.

MX: 7.1+

1 Use Internal Antenna Sets the device to use its built-in Bluetooth/Wi-Fi antenna.

MX: 7.1+

2 Use External Antenna Sets the device to use an (optional) external Bluetooth/Wi-Fi antenna.

MX: 7.1+

Bluetooth Enable/Disable

For KitKat devices on which the Bluetooth radio is Turned On, controls whether the Bluetooth functionality on the device is active.

On Jelly Bean devices, this is the On/Off switch for the Bluetooth radio, which controls whether Bluetooth can be used on the device. If Enabled, the Jelly Bean device user can pair and connect with other Bluetooth devices make changes to the Bluetooth State (active/inactive).

Parm Name: Bluetooth

Option Name Description Requires
0 Do not change This value (or the absence of this parm from the XML) will cause no change to the state of the Bluetooth radio; any previously selected setting will be retained.

OSX: 4.2+

MX: 4.2+

1 Enable On KitKat devices, puts the Bluetooth radio (if Turned On) in an active state. On Jelly Bean devices, Turns On the Bluetooth radio, enabling its usage on the device and changes to its state.

OSX: 4.2+

MX: 4.2+

2 Disable On KitKat devices, puts the Bluetooth radio (if Turned On) in an inactive state. On Jelly Bean devices, Turns Off the Bluetooth radio, preventing its usage on the device and changes to its state.

OSX: 4.2+

MX: 4.2+

Bluetooth Turn On/Off

The On/Off switch for the Bluetooth radio, which controls whether the State of the radio (active/inactive) can be changed by the device user. Turning On the Bluetooth radio allows the device to pair with other Bluetooth devices and connect with devices previously paired.

Note: This parm is available only on devices running KitKat and higher.

Parm Name: BluetoothState

Option Name Description Requires
0 Do not change This value (or the absence of this parm from the XML) will cause no change to the Bluetooth radio state; any previously selected setting will be retained.

GPS Radio On/Off

The On/Off switch for the Global Positioning System (GPS) radio, which allows the device to receive information from GPS satellites to determine the position of the device and controls whether the device user can change the State of the radio (active/inactive).

Parm Name: GPSState

Option Name Description Requires
0 Do not change This value (or the absence of this parm from the XML) will cause no change to the GPS radio usage status; any previously selected setting will be retained.

GPS Location Mode

Permits selection of the GPS Location Mode for determining the device location, allowing for scanrios in which location accuracy can be sacrified in favor of longer battery life. This parm uses Android's three location modes:

  • High Accuracy mode suppliments information from the built-in GPS receiver with Wi-Fi and cellular data to calculate the location with the highest degree of precision. This option draws the most energy.

  • Battery saving mode uses only Wi-Fi and cellular data to determine location, but doesn't work with Google Maps and similar apps. This option draws the least energy.

  • Device only mode uses only GPS data, but is subject to signal loss in some settings.

Parm Name: GPSLocationMode

Option Name Description Requires
0 Do not change This value (or the absence of this parm from the XML) will cause no change to the GPS Location Mode; any previously selected setting will be retained.

MX: 6.1+
