Message cannnot be displayed problem in sms App

[vasanth.king]

Hi,

I created an sms application for the motorola A810. Everything works fine except when i send a message to older nokia phones or nokia phones that don't support java. These phones display a "message cannot be displayed" error. All other phones from different manufactures(LG,Motorola) display the message correctly

Also note i haven't used any specific port while sending my message. Still the problem arises

Here is the excerpt of the code

else if(label.equals("Send"))
{
try
{
clientConn=(MessageConnection)Connector.open("sms://"+name1);
}
catch(Exception e) {
alert = new Alert("Alert");
alert.setString("Unable to connect to Station because of network problem");
alert.setTimeout(2000);
display.setCurrent(alert);

}
try {
TextMessage textmessage = (TextMessage) clientConn.newMessage(MessageConnection.TEXT_MESSAGE);
textmessage.setAddress("sms://"+name1);
textmessage.setPayloadText(Address1);
clientConn.send(textmessage);
}
catch(Exception e)
{
Alert alert=new Alert("Alert","",null,AlertType.INFO);
alert.setTimeout(Alert.FOREVER);
alert.setString("Unable to send");
display.setCurrent(alert);

}
if (clientConn != null)
{
try
{
clientConn.close();
}
catch (Exception e)
{
Alert alert=new Alert("Alert","",null,AlertType.INFO);
alert.setTimeout(Alert.FOREVER);
alert.setString("Unable to close connection");
display.setCurrent(alert);
}

}
}

What is the value of "Address1"? Does it contain only Western European characters, or something else (Cyrillic, Hindi, Chinese...)?

Does the problem only occur if you run the application on the Motorola? Do you have the same problem if you run the app on a Nokia or Sony Ericsson?

It's a sms app for touch screen phones with a custom on screen qwerty keyboard. And it contains only wesern european characters(English).

I hav't tested it on other touch screen phones yet since i dont have access to any other phone models

I assume that the devices which fail to receive your messages are able to receive messages normally. So, there are two possibilities.

1. Your application is sending something strange.
2. The device is sending something strange.

I suggest you write a very small test MIDlet that simply sends a test string. See if you can reproduce the problem. Then try it on another phone.
