APN cached

[eppie]

Hello,

I still have some problems with modules who spontaneously cannot connect anymore to the GPRS network with the exception ' Profile could not be activated' . So I decided to build in a function that will test multiple APN's and send the result by SMS back to me.
No I notice that when I use the SocketConnection class and provide APN information with it, it looks like it is cached when a working APN is found!

In the example beneath ONLY the result will be;
internet --> error
live.vodafone.com --> OK
others --> OK

This is very strange because of the fact that only the live.vodafone.com APN is inteded for the used sim and is also the only one who works! If I change the order the result is that everything works after the live.vodafone.com apn is used!

Anyone noticed this??

Enter
 private void testCommunication(String nr) {
        //Request settings
        Settings settings = Settings.getInstance();
        String host = settings.getString("server.host");
        int port = settings.getInt("server.port");

        sendSms(new SMS(nr, testCommunicationApn(host, port, "internet", "", "")));
        sendSms(new SMS(nr, testCommunicationApn(host, port, "live.vodafone.com", "vodafone", "vodafone")));
        sendSms(new SMS(nr, testCommunicationApn(host, port, "office.vodafone.nl", "vodafone", "vodafone")));
       
        sendSms(new SMS(nr, testCommunicationApn(host, port, "advancedinternet", "", "")));
        sendSms(new SMS(nr, testCommunicationApn(host, port, "internet.maingate", "", "")));
        sendSms(new SMS(nr, "commtest done"));
    }


 private String testCommunicationApn(String host, int port, String apn, String u, String p) {
       
 String gprs = "bearer_type=gprs;access_point=" + apn + ";username=" + u
 + ";password=" + p + ";timeout=" + 0 + ";reverse_dns_lookup=no;";

        SocketConnection c = null;
        InputStream i = null;
        OutputStream o = null;

        try {
            Debug.log(System.out, "ContainerManager --> APN TEST open socket to " + host + " / " + gprs);
            c = (SocketConnection) ConnectionFactory.getSocketConnection(host, port, gprs);            
            i = c.openDataInputStream();
            o = c.openDataOutputStream();
            o.write(0);
           
            Debug.log(System.out, "ContainerManager --> APN TEST open socket OK");
        } catch (IOException e) {
            Debug.log(System.out, "ContainerManager --> APN TEST: " + apn + " ERROR: " + e.getMessage());
            return apn + " Ex:" + e.getMessage();
        } finally {
            if (c != null) {
                try {
                    c.close();
                } catch (Exception ex) {

                }
            }
            if (i != null) {
                try {
                    i.close();
                } catch (Exception ex) {

                }
            }
            if (o != null) {
                try {
                    o.close();
                } catch (Exception ex) {

                }
            }
        }

        return apn + " ok";
    }code here...

Even when I set the APN with AT^SJNET I do not see any difference
