Homebrew [Release] Lua Player Plus 3DS (lpp-3ds) - LUA interpreter for 3DS

When will LPP-3DS be able to support sleep mode? And, out of curiosity, why won't sleep mode work, even on CFW and NH 2.5?

Sleep mode works perfectly, you only have to add sleep mode to your script. (Correct me if I wrong)

Really? How would one go about this?

What do you mean for sleep mode? If you mean pressin Home to return temporary to home menu, yes lpp-3ds already support it with some glitches. (Basically there are some glitches with GPU state restoring that need to be solved).

What I mean is the ability for the program to continue running as usual when the 3DS is closed and opened again (to continue running out of sleep mode, so to speak).

From all the LPP-3DS programs I've used so far, once you close the 3DS and reopen it, the program crashes and you're stuck with a black screen, forcing you to restart the 3DS.

Could someone post a sample of how to recieve a file with sockets from https://example.com/file.zip ? I can't figure it out -_-.

This is what I've done so far to HTTP server, but I get an empty string: (Used a sample I found somewhere else)

I'm printing the string correctly, that's not the problem.
EDIT2: Second try.

Code:

function testsocket()
    Socket.init()
    checksckt = Socket.connect("133.130.123.204", 80, false) -- (Also tried with the domain name ctgp.dshack.org, still doesn't work)
    Socket.send(checksckt, "GET /check.txt HTTP/1.1\nHost: ctgp.dshack.org\n\n")
    checkscktdata = Socket.receive(checksckt, 1024)
    Socket.term()
end

Printing checkscktdata returns an empty string ("")

If you're using latest nightly build, you can use Network module to download via SSL or you can use Socket.connect with third argument set as true (as stated in the documentation: http://rinnegatamante.it/lpp-3ds_doc.html )

The server I'm trying to connect is not SSL (trying to connect with SSL returns "Failed to create SSL connection"), the http request or read is what isn't working. (I don't want to use Network.DownloadFile because I can't make a progress bar with it.)

Your HTTP header is malformed. Should be something like this: https://github.com/Rinnegatamante/T...b/master/PC/downloader/downloader.cpp#L79-L80

I got it working, here is a function to download string using sockets if you want to use it

Code:

function socket_string(string_host, number_port, bool_usessl, string_path, number_stringmaxsize, number_checkfrequency, number_checktimeout)
    checksckt = Socket.connect(string_host, number_port, bool_usessl)
    sockettmr = Timer.new()
    globalsockettmr = Timer.new()
    Socket.send(checksckt, "GET "..string_path.." HTTP/1.0\r\nHost: "..string_host.."\r\n\r\n")
    local checkscktdata = ""
    while (string.len(checkscktdata) == 0) do
        if (Timer.getTime(sockettmr)>=number_checkfrequency) then
            Timer.reset(sockettmr)
            checkscktdata = Socket.receive(checksckt, number_stringmaxsize)
            if (Timer.getTime(globalsockettmr) > number_checktimeout) then
                return "Timed out!"
            end
        end
    end
    Timer.destroy(sockettmr)
    Timer.destroy(globalsockettmr)
    local _,bytesoffset = string.find(checkscktdata, "Length: ")
    checkscktdata = string.sub(checkscktdata, bytesoffset + 1)
    local contentsize = string.match(checkscktdata, '%d+')
    checkscktdata = string.sub(checkscktdata, (string.len(checkscktdata) - contentsize))
    return checkscktdata
end

Example:

Code:

socket_string("ctgp.dshack.org", 80, false, "/check.txt", 4096, 100, 5000)

                Graphics.termBlend()
                Font.print(font,80,150,round((contentsize / 1048576),2).." MB, "..round((progress / 1024),2).." KB/sec, "..SecondsToClock((contentsize - total_size) / (progress + 0.01)),Color.new(255,255,255), TOP_SCREEN)

socket_downloadfile("www.dshack.org", 80, false, "/assets/store/164/0.7update.zip", 4096, 1048576, 10000, "/file.zip", true)

The example downloads a file from dshack.org, in chunks of 4096 bytes, writes to file each MB, and has a 10sec timeout. It downloads at 120KB/sec. (4096 and 1048576 should not be changed to something bigger to prevent file corruption.)

If you're using latest nightly build, you can use up to 32768 bytes as receive size without getting lost bytes issues. (That should also make download process faster since I/O is pretty slow on 3DS and the less you call io.write, the better it will be. (You should consider for example to save something like 15 MB on a temp var and then call a single write every time 15 MB is reached to increase download speed).

Tried to set to 15MB, but at 5MB I get not enough memory :S

Your code? Probably you're not calling a garbage collection.
You can also try to use a more little cache (5MB/10MB)

I think the graphics/music are using ram, I set the limit to 5MB and works fine. 120KB/Sec average speed

Tried to connect to https://dshack.org using ssl sockets with: Socket.connect(www.dshack.org, 443, true). However I'm getting: "Error:[string"?"]:56: SSL connection failed." @Rinnegatamante (Also tried with port 80)

I have a problem when trying to render more than one circle, one the first one shows up. This doesn't happen when I'm drawing something else like rectangles. Here is an example:

Code:

-- Init GPU
Graphics.init()

-- Main Loop
while true do
   
    -- Start printing on top screen
    Screen.refresh()
    Graphics.initBlend(TOP_SCREEN)
   
    -- Draw something on screen
    Graphics.drawCircle(200, 120, 10, Color.new(0, 255, 0))
    Graphics.drawCircle(300, 120, 10, Color.new(255, 0, 0))
   
    -- Terminate printing phase
    Graphics.termBlend()
   
    -- Flip screens
    Screen.flip()
    Screen.waitVblankStart()
   
    -- Exit sample
    if Controls.check(Controls.read(), KEY_SELECT) then
        Graphics.term()
        System.exit()
    end
   
end

Note that this is the GPU example just with circle drawing functions.

Any help would be greatly appreciated

Tried to connect to https://dshack.org using ssl sockets with: Socket.connect(www.dshack.org, 443, true). However I'm getting: "Error:[string"?"]:56: SSL connection failed." @Rinnegatamante (Also tried with port 80)

Thanks to @ksanislo improvements, this should be now solved.

I have a problem when trying to render more than one circle, one the first one shows up. This doesn't happen when I'm drawing something else like rectangles. Here is an example:

Code:

-- Init GPU Graphics.init() -- Main Loop while true do -- Start printing on top screen Screen.refresh() Graphics.initBlend(TOP_SCREEN) -- Draw something on screen Graphics.drawCircle(200, 120, 10, Color.new(0, 255, 0)) Graphics.drawCircle(300, 120, 10, Color.new(255, 0, 0)) -- Terminate printing phase Graphics.termBlend() -- Flip screens Screen.flip() Screen.waitVblankStart() -- Exit sample if Controls.check(Controls.read(), KEY_SELECT) then Graphics.term() System.exit() end end

Unfortunately this is a well known bug in sf2dlib that still needs to be solved. ( https://github.com/xerpi/sf2dlib/issues/9 )

Is there nothing you can do about this? The author says this and this commit from December 2015 fixed the issue

lpp-3ds uses very latest version of sf2dlib. This is not the only project with such issue. Anyway soon sf2dlib will receive a major update migrating the whole backend API to citro3d. In the next weeks, i'll update the whole Graphics module so maybe this change will fix such bug too.

Oh, thanks for the info. Really looking forward to that then
