Guest	Data service turned off Posted: Jul 10, 2008 7:02 PM	Reply
	How can I detect that the data service is turned off or suspended when the network is still up. The case can be created by going to "Manage Connections" on the home screen,leave the "Mobile Network" checked- Select Network Options, then turn off "Data Services". I am using RadioInfo.isDataServiceOperational() and RadioInfo.isDataServiceSuspended(), but none of them is returning the correct value. Am I using the wrong API? If so, what should I use to detect that the "Data Services" is off. Thanks

	Please have a look at the code used in the developer knowledge base article below. How To - Determine when to route data DB-00485 http://tinyurl.com/2hv32n Mark Sohm BlackBerry Developer Journal www.blackberrydeveloperjournal.com

	Mark, thanks for the reply. I tried what was mentioned in the article, but it does not work. The state still shows that there is a data coverage even when the dataServices are turned off. So the case I am testing is the following: The Radio is on, but the user disabled the dataServices as described in my initial message. The BB browser detects this as soon as it is invoked. How does it do that?

I have been able to reproduce this behaviour and will look into it further.  However, as a work around you could use the CoverageInfo.isCoverageSufficient method to check for both MDS and direct TCP coverage.  This method does take into account the users data service setting.

I tried to query different APIs and compare their results in order to conclude. The following is recorded after turning OFF the data services on a GSM SIM-

    1) RadioInfo.getActiveWAFs() & RadioInfo.WAF_3GPP returns Non ZERO    // 3GPP is Active
    2) CoverageInfo.isCoverageSufficient(CARRIER) returns false                   // Carrier coverage is not Sufficient
    3) CoverageInfo.isCoverageSufficient(MDS) returns false                        // MDS coverage is not Sufficient

I was expecting that the Coverage of Carrier (WAP, Direct TCP) and MDS (BES) is Available, however not used by the device, since it is explicitly turned OFF at the device end. But the result is not similar to what I was expecting. On the other hand, WAF_3GPP was explicitly turned Off, so it shouldn't be reported as Active.

Am I expecting incorrectly or there is some thing wrong with these APIs ?

Thanks,

Any one ?

Thanks,

The APIs are working as designed.  The RadioInfo class works at a lower level than CoverageInfo.  When you turn data services off on the BlackBerry side, it only disables it on the BlackBerry itself.  The radio/carrier side still allows for this, which is what the RadioInfo class is returning.

Mark,

In your post in

 http://tinyurl.com/2hv32n

I can see that you are using 

ServiceRouting.getInstance().isServiceRoutable()

method that cannot be found in public API . Is it still safe to use this unpublished API?

Or, should we use isSerialBypassActive() ? What would be the differnece then?

Also, what kind of values can be passed to isDataRoutable() as serviceUID parameter?

Thanks.

[MSohm]

The isSerialBypassActive method should be the one used.  Thanks for pointing this out, I will have the article updated.

What string values can be passed as serviceUID in isDataRoutable() ?

I found that, RIM does not provide API to turn off data services, so may we have to work around by use PersistentObject to change data services value. May the code like this:

PersistentObject persist = PersistentStore.getPersistentObject( OptionsDataServicesData.ID );

persist.setContents( new OptionsDataServicesData() );

persist.commit();

OptionsDataServicesData.ID is a unique long number, example: long MY_DATA_ID = 0x33abf322367f9018L;

but I don't know exactly value. Could someone know value of this ID?

Can anyone help me, please?
