TCPSocket connection refused for Anthem Receiver QuickApp

[Anth 9]

Hi All,

So I have been trying to get a TCPSocket connection to my Anthem receiver using the code below.

Each time I try to connect it returns "connection refused"

The odd thing is - when I go to the Command Prompt on the same laptop I can use telnet using the same details without an issue.

 

Any ideas?

 

Thanks

 

 

QA Code:

 

 

local host = "10.0.0.40"

local port = 14900

 

function QuickApp:onInit()

    self:debug("onInit")

    self:connect()

    self:debug("onInit - connect()")

end

 

function QuickApp:onDataReceived(data)

    self:debug("onDataReceived")

    self:debug("onDataReceived", data)

end

 

function QuickApp:waitForResponseFunction()

  self.sock:read({ -- reading a data package from the socket

      success = function(data)

        self:onDataReceived(data) -- handling of received data

        self:waitForResponseFunction() -- looping of data readout

      end,

      error = function() -- a function that will be called in case of an error when trying to receive data, e.g. disconnecting a socket

        self:debug("response error")

        self.sock:close() -- socket closed

        --fibaro.setTimeout(5000, function() self:connect() end) -- re-connection attempt (every 5s)

      end

    })

end

 

function QuickApp:connect()

    self:debug("connect() - HOST: " .. host .. " PORT: " .. port)

    self.sock = net.TCPSocket() -- creation of a TCPSocket instance

    self:debug("CONNECT() - self.sock = net.TCPSocket()")

    self.sock:connect(host, port, { -- connection to the device with the specified IP and port

      success = function() -- the function will be triggered if the connection is correct

        self:debug("connected")

        self:send("SOCKET IS - " , self.sock)

        self:waitForResponseFunction() -- launching a data readout "loop"

      end,

      error = function(err) -- a function that will be triggered in case of an incorrect connection, e.g. timeout

        self:debug("connection error:",err)

        self.sock:close() -- closing the socket

        self:debug("socket closed")

        --fibaro.setTimeout(5000, function() self:connect() end) -- re-connection attempt (every 5s)

      end,

    })

    self:debug("connect() - connecting")

 

end

 

function QuickApp:onDisconnect()

    self:debug("Anthem onDisconnect");

    self.sock:close()

end

Z1VOL?;  is the query and Z1VOL-40; is the response from the amplifier.

All,

To close this out I have found the issue I was having.

The Anthem AVR actually has two IP addresses - 1 for the AVR and the other for the PlayFi function. By setting the AVR IP under network settings (and in the router for a static IP) you need to make sure its the right MAC address and different from the PlayFi IP.

No works well - just about to publish my first QA to the forum!
