19.3 Sending Binary Messages
The payload of an SMS message can carry binary data. You will need a BinaryMessage instead of a TextMessage, but the basic procedure is the same.
public void sendBinary(String address, byte[] data)
throws IOException, InterruptedException {
String cs = "sms://" + address + ":50001";
MessageConnection mc = (MessageConnection)
Connector.open(cs);
BinaryMessage bm = (BinaryMessage)
mc.newMessage(MessageConnection.BINARY_MESSAGE);
bm.setPayloadData(data);
mc.send(bm);
}
Remember, you've only got 152 bytes in a message, although longer payloads will be split into multiple messages.
