问题
I got a computer with a nokia hooked up to it, and using AT Commands I managed to send text messages through my C# program (using TEXT MODE AT COMMANDS, NOT PDU). It's all working fine and I can recieve messages as well.
I do wish to be able to send a text thats longer than 160 characters. And for that I need to be able to send a multipart SMS. I've searched around for this and my mate has told me that I need to check the header information in bytes on my "long" message, I analyzed the header information on a recieved long text which was: 233 64 248 104 38 32 161. But that doesn't really get me close to being able to send or recieve multipart texts.
Which header information is needed to do this? And how does it work?
回答1:
The headers on an SMS are well described with worked examples here: http://www.spallared.com/old_nokia/nokia/smspdu/smspdu.htm
The specifics of the header for a multipart SMS are given in the Wikipedia page about concatenated SMS: http://en.wikipedia.org/wiki/Concatenated_SMS
