TCP Listener with MLLP

Hi,



I am using Mirth Connect 3.1

I have created a channel where Source is TCP Listener with MLLP.



HL7 Message format from MLLP Sender is

<0B Start Character><MESSAGE HL7><0D Segment Separator><0D 1C 0D End Message>.



On Mirth Channel Listener Settings are

Specific Interface : 127.0.0.1

Port : 6661

Start Bytes : 0x0B <VT>

End Bytes : 0x0D0D1C0D <CR><CR><FS><CR>



Sender is able to connect to my mirth server, Sender is sending HL7 ADT message but from Mirth channel it is not getting received, Though there isn't any errors or exception, But When Sender sends any message, Sender is getting NULL ACK.



Has anyone faced this kind of issue?



Thanks.
