Cellular Manager

EMDK For Xamarin - 2.5

Overview

The Cellular Manager (CellularMgr) controls the way a device's cellular data connection is used. This CSP is supported only on Zebra Android devices equipped with a Wireless Wide Area Network (WWAN) adapter with access a cellular data network. Attempts to use the CellularMgr on unsupported devices will return an error in the Result XML document.

The CellularMgr provides the ability to control the State (active/inactive) and Usage (enabled/disabled) of features. An option's "State" can be thought of as an "On/Off" switch; the feature is available to programs or the device user to make active or inactive as desired. The term "Usage" would be like a cover over the switch, locking it in its current position. When Usage of an option has been Disabled, the cover is closed, and the position of the switch cannot be changed by the user. Enabling Usage lifts the cover, and lets the user make Cellular features active or inactive.

Data Roaming Enable/Disable

Used to control whether the device user has access to the Data Roaming option on the device. When Disabled, Data Roaming cannot be turned on or off programmatically or by the device user.

The Data Roaming Option determines whether a device can communicate over cellular data networks other than the "home" network provided by the mobile operator with which the active SIM card is affiliated. The convenience of communicating over "foreign" networks while roaming must be weighed against the roaming charges imposed by foreign carriers, which can be significant.

Cellular Data Enable/Disable

This feature to be implemented in the future.

Controls whether the cellular connection on the device can be used to transmit data. When Enabled, the state (active/inactive) of the cellular data connection can be controlled programmatically or by the user. When Disabled, the device is prevented from establishing a data connection using the cellular network and the state cannot be changed. This parameter controls only cellular data; voice and SMS messaging apps are uneffected by this setting.

Parm Name: CellularDataUsage

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

1 Turn On Allows a cellular data connection to be established on the device.

MX: 6.3+

2 Turn Off Prevents a cellular data connection from being established on the device.

MX: 6.3+

Cellular Data Limit Enable/Disable

This feature to be implemented in the future.

Controls whether a limit can be placed on cellular data usage on the device. When Enabled, the device user or an app running on the device can access other parameters that turn data limiting on and off and that control the limit value (in MB per month) and the warning message displayed when the limit is reached. If this parameter is Disabled and cellular data is Enabled on the device, there will be no means of limiting data usage over the cellular network, and all related parameters will be inaccessible by apps or the device user.

Parm Name: CellularDataLimitUsage

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

MX: 6.3+

1 Enable Enables a limit to be set on cellular data usage and the state (active/inactive) of the limit to be controlled programmatically or by the device user.

MX: 6.3+

2 Disable Prevents a limit on cellular data usage from being set on the device.

MX: 6.3+

Cellular Data Limit On/Off

This is the On/Off switch for limiting cellular data (in MB per month) on the device, and the selector for applying the Android-default or a custom limitation. When Enabled using the Android default limit, the limit will be the greater of 5GB or 1.2 times the value specified in the Cellular Data Warning Value parameter, to a maximum of 1TB. If the custom limit is selected, the limit will be the value specified in the Cellular Data Limit Value parameter. Once the limit is reached, the cellular data connection is terminated until a new month begins or the restriction is lifted. If no value is specified with the Cellular Data Limit Value parameter, this parameter is ignored and the previously selected Cellular Data Limit State is retained.

Shown if: Cellular Data State is set to "Enable"

Parm Name: CellularDataLimitState

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

MX: 6.3+

2 Enable and set custom limit Limits cellular data usage to the amount set in the Cellular Data Limit Value parameter.

MX: 6.3+

3 Disable Prevents a limit on cellular data usage from being imposed on the device.

MX: 6.3+

Cellular Data Limit Value

Used to specify the limit (in MB per month) of cellular data usage by the device. Once the limit is reached, the cellular data connection is terminated until a new month begins or the restriction is lifted.

Parm value input rules:

  • Integer from 5-1048576 (5MB-1TB) corresponding to the data usage monthly limit

Shown if: Cellular Data State is set to "Enable" and Cellular Data Limit State is set to "Enable and set custom limit"

Parm Name: CellularDataLimitValue

Requires:

  • MX: 6.3+

MX: 6.3+

Set Cellular Data Warning

Used to specify a threshold (in MB per month) for cellular data usage after which a warning is displayed on the device.

Parm value input rules:

  • Integer from 5-1048576 (5MB-1TB) corresponding to the data usage limit

Shown if: Cellular Data State is set to "Turn On" and Cellular Data Warning is set to "Set new warning"

Parm Name: CellularDataWarningValue

Requires:

  • MX: 6.3+

Background Data Enable/Disable

Used to control whether the device user has access to the Background Data option on the device. When Disabled, Background Data cannot be turned on or off programmatically or by the device user.

The Background Data Option determines whether applications that are not in the foreground should be permitted to maintain a data connection over the cellular network (if they are capable of doing so). For example, some email applications continue to download messages while other apps are active or when the device's screen is turned off. The convenience of having data ready "when it's asked for" must be considered when planning for cellular bandwidth utilization and weighed against the potential for data overage and roaming costs.

Parm Name: BackgroundDataUsage

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

OSX: 4.4+

MX: 4.4+

1 Enable Enables Background Data to be used on the device and its state (active/inactive) to be controlled programmatically or by the device user.
