[SDK] Can't receive messages with LrSocket

[Reiep]

Hi!

I need to send messages via sockets to Lr. The communincation between my client and netcat (as a server) goes well, the messages are sent. However, I can't get any messages in Lr. Based on the logs onConnecting, onConnection, onError and onClosed are triggered, but it looks likes onMessage is not. I've replicated this with my client and with netcat as a client.

The lua code is the following:

LrTasks.startAsyncTask(function()
    		LrFunctionContext.callWithContext( 'socket', function( context )
				local running = true
			    local socket = LrSocket.bind {
			        functionContext = context,
			        plugin = _PLUGIN,
			        port = 19684,
			        mode = 'receive',
			        onMessage = function(socket, message)
			            outputToLog("Message!")
			            --Never happens
			            end,
			        onClosed =  function (socket)
			            outputToLog("Closed")
			            running = false
			            end,
			        onError = function (socket, err)
			            socket:reconnect()
			            outputToLog("Error: " .. err) 
			            end,
			        onConnecting = function( socket, port )
			            outputToLog("Waiting for connection on port " .. port)
			            end,
			        onConnected = function (socket, port)
			            outputToLog("New connection!")
			            end}
			    while running do LrTasks.sleep (0.1) end    
			    socket:close ()
			    end )
			    end )

 Do you guys have an idea?

Thanks!

OK, so I found the solution: all the messages must end with a new line (\n) otherwise they are not processed.

Glad you sort it out. 

That silly requirement was never documented, and Adobe has pretty much stopped maintaining the SDK, so there's little point in filing a bug.

If you search this forum for "LrSocket", you can find some previous threads with people discussing their experience, in case you get hung up again.
