SMPP (3.4) Client Library in pure Go.

This library is well tested with SMSC simulators:

• Melroselabs SMSC

go get -u github.com/linxGnu/gosmpp

• From v0.1.4, gosmpp is written in event-based style and fully-manage your smpp session, connection, error, rebinding, etc. You only need to implement some hooks:

		trans, err := gosmpp.NewSession(
		gosmpp.TRXConnector(gosmpp.NonTLSDialer, auth),
		gosmpp.Settings{
			EnquireLink: 5 * time.Second,

			ReadTimeout: 10 * time.Second,

			OnSubmitError: func(_ pdu.PDU, err error) {
				log.Fatal("SubmitPDU error:", err)
			},

			OnReceivingError: func(err error) {
				fmt.Println("Receiving PDU/Network error:", err)
			},

			OnRebindingError: func(err error) {
				fmt.Println("Rebinding but error:", err)
			},

			OnPDU: handlePDU(),

			OnClosed: func(state gosmpp.State) {
				fmt.Println(state)
			},
		}, 5*time.Second)
		if err != nil {
		  log.Println(err)
		}
		defer func() {
		  _ = trans.Close()
		}()

  • In this example, you should run smsc first:
    • Build and run SMSC Simulator:

    g++ example/smsc_simulator/smsc.cpp -o smsc
    ./smsc &

    • Run smpp client in the example: https://github.com/linxGnu/gosmpp/blob/master/example/main.go

    go run example/main.go
