SMPP client implemented in C++

This is a simplified SMPP client lib for sending and receiving smses through the SMPP V3.4 protocol. It only implements a handful of the SMPP features.

Dependencies

To build this library you need and a c++11 compatible compiler:

• Boost.Asio
• Boost.Bimap
• Boost.Bind
• Boost.Date_time
• Boost.Function
• Boost.NumericConversion
• Boost.Thread
• Boost.Tuple
• Boost.System
• [Google gflags] (https://code.google.com/p/gflags)
• [Google gtest] (https://code.google.com/p/googletest)
• Google glog

We have built this library against boost 1.46, but it's known to work with boost 1.47 as well.

The following ubuntu packages should suffice for the dependices: libboost1.46-all-dev and libcppunit-dev.

If you dont wan't all the boost libs, try:

• libboost-system1.46-dev
• libboost-filesystem1.46-dev
• libboost-date-time1.46-dev

Installation

git clone [email protected]:onlinecity/cpp-smpp.git
cd cpp-smpp
cmake .
make
su
make install

There is both an offline unit test (./test/unittest) and an online unit test (./test/livetest). If you run make test you'll run them both via CTest. They can be run individually, which also allows you to view the results from CppUnit. The connection settings for the online test is found in test/connectionsetting.h.

F.A.Q.

How do I enable delivery reports? You must set the registered delivery flag: client.setRegisteredDelivery(smpp::REG_DELIVERY_SMSC_BOTH);

Why do I get 'Failed to read reply to command: 0x4', 'Message Length is invalid' or 'Error in optional part' errors? Most likely your SMPP provider doesn't support NULL-terminating the message field. The specs aren't clear on this issue, so there is a toggle. Set client.setNullTerminateOctetStrings(false); and try again.

Can I test the client library without a SMPP server? Many service providers can give you a demo account, but you can also use the logica opensmpp simulator (java) or smsforum client test tool (linux binary). In addition to a number of real-life SMPP servers this library is tested against these simulators.

How do I set socket timeouts? You cannot modify the connect timeout since it uses the default boost::asio::ip::tcp socket. You can set the socket read/write timeouts by calling client.setSocketWriteTimeout(1000) and client.setSocketReadTimeout(1000). All timeouts are in milliseconds.
