how do we detect whether the device has network coverage or not?

the following QT code doesn't work:

manager->networkAccessible()==QNetworkAccessManager::NotAccessible

is there some BB10/Cascades specific API we should be using?

[lew]

been weeks, still can't find an API that says whether the device is IN COVERAGE or OUT OF COVERAGE...

no one solved this issue ??

I'd be interested in a solution to this as well. Been trying to figure out how to detect the following internet access scenarios:

- Wifi Only available
- Wifi and Cellular available
- Cellular available

A couple of my apps would benefit from being able to switch between the connection that they use. A good first step would be figuring out if Internet "coverage" is available.

got the answer from the bb10 developer relations team:

http://qt-project.org/doc/qt-4.8/qnetworkconfigurationmanager.html

some sample code would be great ;-)

[lew]

the code is in the link i put . . .

bool QNetworkConfigurationManager::isOnline () const
Returns true if the system is considered to be connected to another device via an active network interface; otherwise returns false.
This is equivalent to the following code snippet:
 QNetworkConfigurationManager mgr;
 QList<QNetworkConfiguration> activeConfigs = mgr.allConfigurations(QNetworkConfiguration::Active)
 if (activeConfigs.count() > 0)
     Q_ASSERT(mgr.isOnline())
 else
     Q_ASSERT(!mgr.isOnline())

thx - have seen this

was asking if someone has a real-world-sample:

automatic-detect-of-changing network coverage with slot/signals if wifi comes/goes and radio comes/goes

using bps, you can get events delivered to you pertaining to network status.  using netstatus.h, you can also call netstatus_get_availability().

/**
* @brief Indicate whether the network is available
*
* The @c netstatus_get_availability() function indicates whether a network
* connection is available.
*
* @param is_available If @c true the network is available, if @c
* false the network is not available.
*
* @return @c BPS_SUCCESS upon success, @c BPS_FAILURE with @c errno set
* otherwise.
*/
BPS_API int netstatus_get_availability(bool *is_available);

you can determine which is default by asking for the default interface - netstatus_get_default_interface().

/**
* @brief Get the default interface
*
* The @c netstatus_get_default_interface() function gets the default interface.
*
* @param interface This will be populated with the default interface. May be
* NULL if there is no default interface. The caller must call @c bps_free()
* when done with this string.
*
* @return @c BPS_SUCCESS upon success, @c BPS_FAILURE with @c errno set
* otherwise.
*/
BPS_API int netstatus_get_default_interface(char **interface);
