Dear All

I send request from OpenHIM to MedicCR by Transport ER7 over LLP

and i get this error

3/14/2017 4:11:23 PM : ClientRegistry.exe Error: 0 : 3/14/2017 4:11:23 PM : System.InvalidOperationException: Invalid LLP First Byte

at MARC.HI.EHRS.CR.Messaging.HL7.TransportProtocol.LlpTransport.OnReceiveMessage(Object client)

i try to add some string in-front that mes but it not work.

but if i change to ER7 over TPC it work fine.

Maybe i miss some config?

Thanks In advent

Hi Sovannoty,

The LLP receiver looks for a vertical tab (VTAB) character as the first byte of a message and requires a file separator (FS) carriage return (CR) at the end of the message. This is because LLP allows you to stream messages and these characters represent the start/stop of individual messages in the stream.

If you send

MSH|…
PID>…

You should receive an acknowledgement in the same format.

Cheers
