# SMPP 3.4
[](https://godoc.org/github.com/fiorix/go-smpp) [](https://goreportcard.com/report/github.com/fiorix/go-smpp) [](https://travis-ci.org/fiorix/go-smpp)
This is an implementation of SMPP 3.4 for Go, based on the original
[smpp34](https://github.com/CodeMonkeyKevin/smpp34) from Kevin Patel.
The API has been refactored to idiomatic Go code with more tests
and documentation. There are also quite a few new features, such
as a test server (see smpptest package) and support for text
transformation for LATIN-1 and UCS-2.
It is not fully compliant, there are some TODOs in the code.
## Usage
Following is an SMPP client transmitter wrapped by an HTTP server
that can send Short Messages (SMS):
```go
func main() {
// make persistent connection
tx := &smpp.Transmitter{
Addr: "localhost:2775",
User: "foobar",
Passwd: "secret",
}
conn := tx.Bind()
// check initial connection status
var status smpp.ConnStatus
if status = <-conn; status.Error() != nil {
log.Fatalln("Unable to connect, aborting:", status.Error())
}
log.Println("Connection completed, status:", status.Status().String())
// example of connection checker goroutine
go func() {
for c := range conn {
log.Println("SMPP connection status:", c.Status())
}
}()
// example of sender handler func
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
sm, err := tx.Submit(&smpp.ShortMessage{
Src: r.FormValue("src"),
Dst: r.FormValue("dst"),
Text: pdutext.Raw(r.FormValue("text")),
Register: pdufield.NoDeliveryReceipt,
TLVFields: pdutlv.Fields{
pdutlv.TagReceiptedMessageID: pdutlv.CString(r.FormValue("msgId")),
},
})
if err == smpp.ErrNotConnected {
http.Error(w, "Oops.", http.StatusServiceUnavailable)
return
}
if err != nil {
http.Error(w, err.Error(), http.StatusBadRequest)
return
}
io.WriteString(w, sm.RespID())
})
log.Fatal(http.ListenAndServe(":8080", nil))
}
```
You can test from the command line:
```bash
curl localhost:8080 -X GET -F src=bart -F dst=lisa -F text=hello
```
If you don't have an SMPP server to test, check out
[Selenium SMPPSim](http://www.seleniumsoftware.com/downloads.html).
It has been used for the development of this package.
## Tools
See the tools under `cmd/`. There's a command line tool for sending
SMS from the command line, and an HTTP server with WebSocket support.
