TCP receive with DENON Amplifier
#1
Hi!
I am trying to connect DENON Amplifier with TCP. 
While I can send message successfully to DENON, I cannot receive reply from it.
With my laptop I tried TCP with telnet and confirmed that DENON gives back response to my terminal.

Following is what I have tried with resident script (interval = 0) but I got no message.

Thank you very much in advance!

Code:
if not server then   require('socket')   server = socket.udp()   server:setsockname('127.0.0.1', 5485) end if not tcp then     tcp = assert(socket.tcp())     local res, err = tcp:connect('192.168.0.1', 23)     if res then       return tcp     else       tcp:close()       return nil, err     end end function denon_receive(tcp) res, err = tcp:receive()   if not res then     return nil, err   end    return res end while tcp do   res, err =denon_receive(tcp)     if res ~= nil then       log(res,err)     end     if (res == nil) then       log('no response')     end end

receive without timeout will wait until a new line (\n) character is received.

Try this script instead:
Code:
sock = require('socket').tcp() sock:settimeout(10) res, err = sock:connect('192.168.0.1', 23) if res then   while true do     res, err, partial = sock:receive()     if res then       log('receive', res)     elseif partial then       log('partial', partial)     elseif err == 'closed' then       break     end   end else   log('connect failed', err) end sock:close()

Thank you admin!
It did solve the issue and I can now get the reply from the amplifier!
The issue was, as you said, this amplifier replies message without a single new line (\n) character....

Thank you so much as always!
