I'm using 2 Enfora Enabler-II G Modems on COM1 and COM2,
respectively. When I use the SendMessage and ReadMessage examples,
I've encountered some really strange behavior trying to send a PDU
using OutboundBinaryMessage. The message says it was sent
successfully, but never shows up. I compared the PDU byte array
generated from SMS lib by the bytes that I use in a terminal to use AT
commands to send the exact same message. There was one difference
between the way I've historically sent the command and the way SMSLib
was sending the command:
My way read 0004 after the phone number octets
SMS lib read 00F4 after the phone number octets.
Strangely, if I go into Pdu.java and comment out the or of
DCS_CODING_GROU_DATA, like this, the ReadMessage example gets my PDU
successfully.
public void setDataBytes(byte[] dataBytes)
{
this.dataBytes = dataBytes;
this.decodedText = null;
// clear the encoding bits for this field 8-bit/data
this.dataCodingScheme &= PduUtils.DCS_ENCODING_MASK;
this.dataCodingScheme |= PduUtils.DCS_ENCODING_8BIT;
// this.dataCodingScheme |= PduUtils.DCS_CODING_GROUP_DATA;
}
So my question is this-- why would commenting out the
DCS_CODING_GROUP_DATA line result in me being able to receive my 8-bit
binary PDU message, whereas with it uncommented I don't? Is this a
bug in the library, a unique "feature" of my modems, or outright user
error?
Thanks,
Jason
