Defined in:
lib/smpp/transceiver.rb

Overview

The SMPP Transceiver maintains a bidirectional connection to an SMSC. Provide a config hash with connection options to get started. See the sample_gateway.rb for examples of config values. The transceiver accepts a delegate object that may implement the following (all optional) methods:

mo_received(transceiver, pdu)
delivery_report_received(transceiver, pdu)
message_accepted(transceiver, mt_message_id, pdu)
message_rejected(transceiver, mt_message_id, pdu)
bound(transceiver)
unbound(transceiver)
