ACK message generation

[vijendra rao]

I am trying to generate an ACK message like below.

recieved_msg = HL7::Message.new

recieved_msg.parse @buf

msh = recieved_msg[:MSH]

if msh 

  ack_msg = HL7::Message.new

  msh_ack = HL7::Message::Segment::MSH.new

  msh_ack.enc_chars = msh.e1

  msh_ack.sending_app = 'test'

  msh_ack.sending_facility = 'test'

  msh_ack.recv_app = msh.e2

  msh_ack.recv_facility = msh.e3

  msh_ack.message_type = "ACK^#{msh.e8.split('^')[1]}"

  msh_ack.message_control_id = msh.e9

  msh_ack.processing_id = msh.e10

  msh_ack.version_id = msh.e11

  msa_ack = HL7::Message::Segment::MSA.new

  msa_ack.ack_code = 'AA'

  msa_ack.control_id = msh.e9

  msa_ack.text = 'Received successfully'

       

  ack_msg << msh_ack

  ack_msg << msa_ack

  

  send_data ack_msg.to_mllp

end

 

But ack_msg.to_mllp is not generating properly. Can some one please help me in this?
