Web and WebWorks Development

I must be missing something. I'm using the following to determine whether the device has a WiFi connection:

function onWiFi() {

var networkConnections = blackberry.network;

return (networkConnections.indexOf("Wi-Fi") != -1);

}

I ran this on my 9900 after I turned off my WiFi and it still returned true.

I logged the values of blackberry.network and it returns 3GPP,Wi-Fi whether the WiFi is on or not.

Am I missing something or do I misunderstand the documentation?

Thanks in advance!

Documentation of blackberry.system.hasDataCoverage () mentions there can be a small delay (2-3 secs) between the time the device connects until the method returns true. I assume you waited longer than that.

If you also switch off 3G, what does blackberry.network return then??

That's an interesting idea. I turned off all connections and went to grab a coffee. I came back and ran the app again and it still insisted that I had a WiFi connection. The log shows blackberry.network returning 3GPP, Wi-Fi.

The blackberry.network object is simply a string.  Unless you reload the page (and refresh the JavaScript runtime), its values does not dynamically change when you disable the radio.  So the behavior you have described is what I would expect to see if you remain on the same page when you switched out and disabled the WiFi radio.

Are you working in the browser, or a webworks application?  If the latter, an alternative solution could be to use the blackberry.system.hasCapability("network.wlan") method which should always return a live result:

https://developer.blackberry.com/html5/apis/blackberry.system.html#.hasCapability

This should return true/false when WiFi is enabled/disabled.

Still no luck.

It's a WebWorks application.

I changed the code to output the results of blackberry.system.hasCapability("network.wlan")

I installed the app and turned off my WiFi on the 9900. I waited for two minutes and then started the app. 

blackberry.system.hasCapability("network.wlan") still returns true.

Hi,

I have the same problem. To test my Wifi-connection after the Foreground-Event "app.event.onForeground" I use: 

 if (blackberry.system.hasCapability("network.wlan")) {
		 alert('connected')
		location.reload(true);} 
		else{
			alert('not connected')
		}

 It always return "true" as result even if I turn the wifi off.

I hope someone can give an advise to me.

Thank's!

I have found the solution for my problem.

Now I use: 

 if (blackberry.system.hasDataCoverage()) {
		 
		location.reload(true);} 
		else{
			return Tryagain();
		}

It work's fine!

I think these code will help you:

if(!navigator.onLine)

here navigator.onLine returns True and !navigator.onLine returns false..

blackberry.system.hasDataCoverage()
for checking data coverage

blackberry.system.hasCapability("network.wlan")
for checking the string you have passes..
