 Posted: Sun Mar 26, 2006 5:33 pm Post subject: Socket.connect() not working |
 |
|
I am having a problem with a wlan-test program I modified. When it executes Socket.connect() the wlan light is on but not blinking, and it just stays that way (maybe frozen, I don't know). Can anyone look at the code and find out if this is a simple coding error or something wrong with my psp?
| Code: | white = Color.new(255, 255, 255)
offscreen = Image.createEmpty(480, 272)
offscreen:clear(Color.new(0, 0, 0))
y = 0
x = 0
function printstr( text )
local char = ""
for i = 1, string.len(text) do
char = string.sub(text, i, i)
if char == "\n" then
y = y + 8
x = 0
elseif char ~= "\r" then
offscreen:print(x, y, char, white)
x = x + 8
end
end
screen:blit(0, 0, offscreen)
screen.waitVblankStart()
screen.flip()
end
function println( text )
printstr(text .. "\n")
end
site = "www.luaplayer.org"
file = "wlan-test.txt"
host = "www.lua.org"
println("starting wlan...")
Wlan.init()
println("")
println("current configs:")
configs = Wlan.getConnectionConfigs()
for key, value in configs do
println(key .. ": " .. value)
end
println("")
println("using first connection...")
Wlan.useConnectionConfig(1)
println("")
println("resolving ip...")
while true do
ip = Wlan.getIPAddress()
if ip then break end
System.sleep(100)
end
println("psp ip: " .. ip)
println("")
println("connecting to: " .. site)
sock, error = Socket.connect(site, 80) -- ERROR HERE
println("")
println("waiting for connection... press start to abort")
abort = false
while not sock:isConnected() do
if Controls.read():start() then
abort = true
break
end
System.sleep(100)
end
if abort == false then
println("connected to " .. tostring(sock))
println("")
println("http connect as host: " .. host)
println("loading page... press start to abort")
sock:send("GET /" .. file .. " HTTP/1.0\r\n")
sock:send("host: " .. host .. "\r\n\r\n")
header = ""
while true do
buffer = sock:recv()
if string.len(buffer) > 0 then
header = header .. buffer
startIndex, endIndex = string.find(header, "\r\n\r\n")
if endIndex then
printstr(string.sub(header, endIndex))
break
end
end
if Controls.read():start() then
break
end
end
sock:close()
end
Wlan.term()
println("")
println("press start to exit")
while not Controls.read():start() do end |
Thanks for your time!

Okay, I tested my wifi connection under network settings and everything checks out okay. So it is not a problem with my psp's wifi or, if anyone tells me otherwise, my code. It must be something corrupted in luaplayer... I will download it again and see if that doesn't fix it.

This is messed up... Earlier (before I last posted) I modified the script and it got past the connection freeze, but it wouldn't resolve www.luaplayer.org's correct ip address and kept on giving me an error page. Now, even when I use the above code it freezes up when it says "using first connection..." The wlan light stays solid for two seconds then the light turns off. Can anyone please help me with this problem?

I have a similar problem. I can't use sockets in my apps. If I use them the program freezes at the instruction
| Code: | | Wlan.useConnectionConfig(1) |
i use eloader 0.97, luaplayer 0.16, firmware 2.60
what's the problem? |

i found the problem... eloader 0.97 with luaplayer needs a dhcp connection.
But now i have another problem with wifi:
when i do
| Code: |
socket, error = Socket.connect(host, port)
while not socket:isConnected() do System.sleep(100) end
|
the program seems to fall in an infinite loop.
What could i do? |

Same thing happens to me. The program freezes, but the home-button etc. still work. I guess this means it isn't necesairely my fault? Or are we doing something wrong. BTW I use 0.16 and have firmware 1.5. |

| 0.16 has no DNS you will have to type the ipaddress manual. Example. 192.168.1.1 |

aaaah thanks alot. Ill try that.
BTW you use 192.168.1.1 as an example. Maybe a very stupid question, but that's for a LAN or am i wrong? So does that mean i should connect like that to my router or something and then make it go for a page or whatever? |

From Luaplayer changelog:
| Quote: |
v0.16 (all changes for this version by Shine)
================================================
- Wlan:getIPAddress bugfix: now it returns nil on error and the
IP address otherwise
- DNS resolving. Now you can write
Socket.connect("www.luaplayer.org", 80) instead of
Socket.connect("212.227.39.202", 80),
thanks to ideas how to use the resolver lib from PSPRadio
- when loading JPEGs, the file was not closed
- System.md5sum bugfixing for the Windows version
- Wlan.useConnectionConfig index is 1 based instead of 0 based, like usual in Lua
- System.powerTick added: this prevents power off, now you can nail
your PSP on a wall for your electronic painting :-)
- System.createDirectory, System.removeDirectory and System.removeFile added

maybe you missed DNS in wlan configuration... |

What exactly do you mean by that? Can I change something with regards to DNS or anything? |

I guess i just don't know enough about this.
Maybe you could help me with this? I used parts from the wlan example in LUA-player.
This is what i have. First it asks for a name for the session. Then it asks you to choose the connection. This all works, but when i choose one, the wlan light stays on for 2 seconds and then it freezes, like said before.

Still haven't figured this out. I just wanted to add this:
If I select a connection and tell it to connect, it doesn't even show "opening server socket...". So I think this means "Wlan.useConnectionConfig(wy)" isn't working. Or atleast I dont get it to work...
Also in the wiki it says to use "Socket:createServerSocket(port)" and not "Socket.createServerSocket(port)" (one is with a colon and one with a dot). While the example of the Wlan uses the one with the dot. So which one is it? |
