Hi Bryce/Everybody. I am having some issues sending Wap Push messages There has been plenty of talk so far but once and for all when i sort this out I will put up a full post about how to do it properly, anyway on with my problem. I am using a Nokia Artuse CIMD2 SMSC I am receiving garbage text on the mobile So what am I doing.... I know that a wap push over SMS looks like WP = UDHeader + WSPHeader + WBXMLdata The format i am using is this... a UDH which would look like 0B050423F023F00003840101 or 06050423F023F0 basically this breaks down as 0B // User Data Header Length 05 // UDH IE: Port numbers 04 // Port number length 23 // Destination port (high) F0 // Destination port (low) 23 // Originating port (high) F0 // Originating port (low) 00 // UDH IE SAR 03 // UDH SAR IE length 84 // Data gram ref number 01 // Total number of segments in data gram 01 // Segment count I have used ports 23F0 = 9200 Is this correct? i think so WSPHeader I use this code to create the header (taken from Nokia OTA Service Settings document) String ContentType="text/vnd.wap.si"; String WapPush; WapPush.Append(ToHex(0x01)); // Transaction/Push ID WapPush.Append(ToHex(0x06)); // PDU TYPE WapPush.Append(ToHex(ContentType.Length+4)); // Header Length WapPush.Append(ToHex(ContentType.Length+1)); // Value Length strlen ("text/vnd.wap.si"+1) WapPush.Append(ToHex(ContentType)); // text/vnd.wap.si WapPush.Append("00"); // End of string WapPush.Append(ToHex(0x81)); // Charset WapPush.Append(ToHex(0xEA)); // UTF-8 giving WSPheader = 01061310746578742F766E642E7761702E73690081EA [Function ToHex() just converts the data to hex strings] is this header correct? WBXMLdata Next I create the binary WBXML data which specifies the URl etc. I am using this XML.. <?xml version="1.0"?> <!DOCTYPE si PUBLIC "-//WAPFORUM//DTD SI 1.0//EN" "http://www.wapforum.org/DTD/si.dtd"> <si> <indication href="http://www.xyz.com/abc.wml" si-id=1> hello </indication> </si> and i create it according to Doc, "wap-167-serviceind-20010731-a.pdf" the code goes like // WBXML1.1 data WapPush.Append(ToHex(0x02)); // <?xml version="1.0"?> WapPush.Append(ToHex(0x05)); // <!DOCTYPE si PUBLIC "-//WAPFORUM//DTD SI 1.0//EN" "http://www.wapforum.org/DTD/si.dtd"> WapPush.Append(ToHex(0x04)); // 0x6A=Charset=UTF-8 0x04=Charset=iso-8859-1 WapPush.Append(ToHex(0x00)); // String table length WapPush.Append(ToHex(0x45)); // <si> (with content) WapPush.Append(ToHex(0xC6)); // <indication> (with content and attributes) WapPush.Append(ToHex(0x0D)); // href="http://www. WapPush.Append(ToHex(0x03)); // inline String follows WapPush.Append(ToHex("xyz")); // The URL WapPush.Append("00"); // End of string WapPush.Append(ToHex(0x85)); // .com/ WapPush.Append(ToHex(0x03)); // inline String follows WapPush.Append(ToHex("abc.wml")); // MMS Filename WapPush.Append("00"); // End of string WapPush.Append("11033100"); // si-id=1 WapPush.Append(ToHex(0x01)); // end of indication attribute list WapPush.Append(ToHex(0x03)); // inline String follows WapPush.Append(ToHex("hello")); // Message WapPush.Append("00"); // End of string WapPush.Append(ToHex(0x01)); // end of <indication> element WapPush.Append(ToHex(0x01)); // end of <si> element Finally this creates the data WBXMLdata = 0205040045C60D0378797A0085036162632E776D6C0011033100010368656C6C6F000101 so I use header 0B050423F023F00003840101 and data 01061310746578742F766E642E7761702E73690081EA0205040045C60D0378797A0085036162632E 776D6C0011033100010368656C6C6F000101 but I am getting the garbage text can anybody tell me what I am doing wrong Thanks for any help Alan | |||

Hi Alan, Have you tried configuring NowSMS to use a CIMD2 connection? It builds the WAP Push PDU automatically ... There may be other problems in your push attempt, but the destination port is definitely incorrect. The decimal value for the WAP Push port is 2948 (not 9200). -bn | |||
