Hi, 

I could successfully connect to the server and get data when there is WIFI. But when wifi is not available it fails. Using

ConnectionFactory factory = new ConnectionFactory();
factory.setPreferredTransportTypes(new int[]{
TransportInfo.TRANSPORT_TCP_WIFI,
TransportInfo.TRANSPORT_TCP_CELLULAR,
TransportInfo.TRANSPORT_WAP,
TransportInfo.TRANSPORT_WAP2,
TransportInfo.TRANSPORT_MDS,
TransportInfo.TRANSPORT_BIS_B
});

ConnectionDescriptor conDescriptor  = factory.getConnection("url");
int test5= conDescriptor.getTransportDescriptor().getTransportType();
int[] test =TransportInfo.getAvailableTransportTypes();
boolean test1 = TransportInfo.hasSufficientCoverage(6);
boolean test2 = TransportInfo.hasSufficientCoverage(1);
boolean test3 = TransportInfo.isTransportTypeAvailable(1);
String t = (TransportInfo.getTransportTypeName(1));

When I debug Test1 = false but test2 and test3 both returns true. Still the conDescriptor is null

Please help,

Janaka

Hi Janaka,

Did you set the APN for the TCP Cellular connection? 
ConnectionFactory#setTransportTypeOptions(int transPortType, TcpCellularOptions) 

If not already set on your device, this would be required to make the connection for most carriers.

Hi Garett,

Thank you very much for your response. Yes it was APN issue. Working fine now.
