nodemcu _ esp8266 server recieved data from android app and forward to esp8266 client - sockets

Question

I am new programmer esp8266 with lua. I have 2 esp8266 and 1 android phone. One esp8266 is my server and another esp8266 is client. I want to send data from android app to server and server forward this data to esp8266 client. I programed server and client but i think it's wrong, the server received data from phone but not forward it to client.
The server listen on port 9000 and when received data forward it on the port 9999.and esp8266 client listen port 9999.
it is my esp8266 server code:
Can anyone help me?
wifi.setmode(wifi.SOFTAP)
wifi.ap.config({ssid="novin",pwd="12345678"})
print(wifi.ap.getip())
if sv~=nil then
sv:close()
end
function creat_server()
sv = net.createServer(net.TCP)
sv:listen(8080, function(c)
c:on("receive", function(c, pl)
if(pl~=nil) then
print(pl)
data=pl
pl=nil
end
end)
end)
if(data~=nil) then
sck(data)
data=nil
end
end
function sck(data)
sv:listen(9000,function(cc)
cc:send(data)
cc:on("receive", function(cc, dt)
print(dt)
data1=dt
end)
cc:on("sent",function(cc)
print("data send!!!!!!!!!!")
end)
end)
end
creat_server()

I saw your other question which was put on hold, your idea has a little bit problem. The esp which is server can't "Forward" data as you mean it, what I mean is that it can't be server and client at the same time, let it be server all the time. So let's review and recreate the scenario again:
You have android application which acts as a client and it will send some data to server node via POST method, there you get it and store it. you can then get the data on client node via GET method from previous server node. this is one way.
About the way you mentioned, first of all the ports in the code you have provided are different from what you have said in your question, other than that you need to first init node as SOFTAP and get the data and after that config it as STATION and send data via http module.
To simply put it, the code you have provided is too imperfect.
EDIT:
You can get all the docs and mini-examples you need from this site,
and in case you need http module, check out this part of that site.
Here's the doc indicating how to configure your wifi correctly according to your needs.
P.S. Http module has been added recently to the firmware, in case you want to use it and your IDE won't recognize it's syntax, use build cloud to build your own firmware, it will take only 5 minutes.
Also it was much easier for me to move forward with documents rather than example codes in the websites, it's up to you to chose which ever you want.
