In addition to what Laurie said, this part of your reply looks like ASCII where
the QTime field should be: 4c4f47474552
"adbccbda000000020000000400000006
---> 4c4f47474552 = LOGGER

I have digged deeper in my problem:
a) Network infra: The server uses a multicast group. There is no router between
the WSJT-X client and the server; only a switch. I have verified with tcpdump
on both sides that the packet are seen by both camps.
b) I have written a quick PHP client that I have plugged on the same network as
the server and the WSJT-X client. The server and the PHP client establish a 2
way dialog with no pain. The WSJT-X client stays deaf. However it speaks as
expected.
For example, I receive this DECODE message from WSJT-X:
2018/03/22 20:07:59 server.php - Received 66 bytes from remote IP:

The server asks WSJT-X to initiate a response with this message:

WSJT-X ignore the message. But the PHP client decodes it no worries:

I have read in MessageNetwork.hpp the the id must be the Target unique id. I
tried with the WSJT-X client id and with something else.... to no avail.
I have noted a difference between the mode from DECODE message (the letter ~)
and the mode from the STATUS message (plain text FT8). None of them awake
WSJT-X client.
I must say that I could use some help from here! I really am at a loss to
understand what goes on here.
Any taker ?
Cheers

Good Evening
While I am able to received and decode all the messages that come out of WSJT-X
via UDP, I have some difficulties to get WSJT-X client to accept the server
type 4 messages.
I have checked in the settings all 3checkboxes "Accept UDP requests", "Notify
on accepted UDP request", "Accepted UDP requests restores windows" in the hope
to get some feedback from the client.
I was expecting some updates on the client window with some of the data
contained in the UDP message I send and an acknowledgement and/or an error
message.
But my messages must be ill-formed, for I get out of WSJT-X nothing except when
the UDP message is really, and voluntarily, broken (there is a popup window
screaming about bad format).
I use version 1.9rc2 on Win7 pro, and this version works like a charm when used
manually (I mean with the mouse/keyboard).
I have double checked the message format I send and I am pretty confident that
it is following the definition in NetworkMessage.hpp
Should my expectations be correct, is there a way to get more details about
what happens to WSJT-X when it gets my message, such as error messages, trace
log, etc?
I could not find anything on UDP dialog in the User's manual nor did I find a
startup option or something else to help me.
Thank you for your answers
73, Serge
PS: keep up the very good work guys! FT8 is fun! Cheers!
Serge,
Looks to me that your sending a different Time value from that received in the
decode.
DECODE time : [72465000 -> 20:07:45]
SEND TO WSJT-X time : [0451ba68 -> 0451ba68 -> 20:07:45]
Not sure how both 72465000 & 0451ba68 can represent the same time value. Try
using the Time value received in the decode packet.
