smpp

README

go-smpp

A complete implementation of SMPP v5 protocol, written in golang.

Key features

• Message encoding auto-detection

• Multipart SMS automatic splitting and concatenating

• Supported encodings:

  UCS-2     GSM 7bit  ASCII      Latin-1
  Cyrillic  Hebrew    Shift-JIS  ISO-2022-JP
  EUC-JP    EUC-KR
  

Caveats

• Please read the SMPP Specification Version 5 first. pdu is not limited to any value range.
• If you do not like the default session.go implementation, you can easily replace it.
• Device-specific Caveats
