A .NET / .NET Core library for parsing PDU-Mode SMS and decoding 7-bit, 8-bit, USC2 data.

Firstly, clone or download full source.

Then run:

cd sms-decoder
./test.sh

If you have a GPRS device (for example: SIM900A), you may connect it via serial, and modify ser.py:

ser = serial.Serial("<YOUR_DEVICE_SERIAL>")

Make sure your divice is in PDU-mode, then run:

./test-at.sh

And send a sms from another divice or even cellphone.

You'll see the decoded sms.

An easy way to use it in .NET (Core) is like:

SmsDecoder.Helper.Decode (hexStrOrBytes);

But it's not support long sms which is split into many parts.

So, in production environments, you should use MessagePool �just like:

public static void onCompleteMsg (SmsDecoder.Message msg) {}
var pool = new SmsDecoder.MessagePool (onCompleteMsg);
pool.Add (SmsDecoder.Helper.Decode (...));

For full source, please reference to test/Program.cs.

• sms-decoder.sln: .NET Core 2.0 solution file.
• doc: some useful document about pdu format.
• lib: library source code.
• test: a demo for this library.
• test.sh: includes some captcha sms sample to test decoding.
• ser.py: python script to connect GPRS device via serial.
• test-at.sh: build solution, simply parse AT commands from ser.py, and real-time decode sms'.
