@Wilberforce, I started this conversation after seeing that on arduino my boards were doing ~100kb/sec, while on espruino it was only 1kb/sec, for server a file. In fact, I am using espruino since the v1.91, and all that time I thought it was a hardware limitation of esp8266. But it seems to me that the problem comes from the dSnd buffer sent slowly, every 200m, in small pieces of 256bytes.
As it works faster on arduino, the board is not defective. It works the same way on the 2 nodemcu-e12 v2 & v3 that I have. I restarted the router, and tried AP alone (at 20cm from my laptop), station alone and AP+ST, still the same damn result !
@MaBe, I found it at ps-poll even though it was in AP+ST mode. No change when I set it to "none" using with Wifi.setConfig({powersave:"none"}).
@ClearMemory041063, I tried without improvement also flashing the last expressif firmware with the expressif flashing tool like you did, just in case. I used "esp_init_data_default_v05.bin", because there was no "esp_init_data_default.bin". I could not get it working without also changing addresses of this file and of "blank.bin" to 0x3fc000 and 0x37e000. I got a nice :
AT+GMR AT version:1.4.0.0(May 5 2017 16:10:59) SDK version:2.1.0(116b762) compile time:May 5 2017 16:37:48 OKThen I reflashed espruino, this time with expressif flashing tool. I used the files from this url. I used the addresses from your link and I tried with "blank .bin" at 0x3FE000 like I used to do, both works same way. Still as slow as before.
I tried other browsers too, older espruino versions (v1.91, v1.94). The strangest that no one else ever have or noticed this problem before.

So you're a lucky guy, it's working fast for you for 2 different esp8266 based boards..
I really don't understand what's wrong with my nodemcu-e12. I don't have any other esp8266 to try. I installed mine with the same files, but using esptool. If I install last espressif firmware before, it wont make a difference, it will be erased by esptool, right ?
I still get a slow download.

Hmm, that's interesting, it seems hardware related. Your Sparkfun Thing dev-board rocks with espruino !
I don't get your result, with both my poor nodemcus-e12 v3 with 1.95.0 not 4mb , and my v4 lolin with 1.95.20 4mb.
Where can I find this flash map 256/256 you used ?

The other lines comes from the interval every 100ms looking and printing how long is the dSnd buffer, and I see it decreasing in my output. Strange that the interval does not seem to start at all in your setup.

Thanks @ClearMemory041063 for giving attention to my problem, and for the codes to try. You are not testing them on an esp8266, are you ? The last code makes 11,5kb minified, it does not fit, it interrupt the transfer from the IDE. So I had to remove the connecting code and reduce the data to send to 3kb. I cannot send more at once without getting memory errors.
Unfortunately, at the end, the result with ws is as slow as with http: 2.5sec for 3kb (see the code below). Maybe because ws server is built on top of an http server.
var n = 5, chk=3*1024; var tdata=new Uint8Array(chk); var i; for(i=0;i<1024;i++){ tdata[i]=0x30; tdata[i+1024]=0x31; // tdata[i+1024*2]=0x32; // tdata[i+1024*3]=0x33; // tdata[i+1024*4]=0x34; }//next i var page = '<html><body><script>var ws;setTimeout(function(){'; page += 'ws = new WebSocket("ws://" + location.host + "/my_websocket", "protocolOne");'; page += 'var t=(new Date()).getTime();ws.onmessage = function (event) { console.log("t:",(new Date()).getTime()-t,"MSG:",event.data); };'; page += 'setTimeout(function() { ws.send("Hello to Espruino!"); }, 1000);'; page += '},1000);</script></body></html>'; function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.end(page); } var server = require('ws').createServer(onPageRequest); server.listen(80); server.on("websocket", function(ws) { ws.on('message',function(msg) { print("[WS] "+JSON.stringify(msg)); }); var t=getTime(); ws.send(E.toString(tdata)); print("n=",n,"t:",(getTime()-t).toFixed(3),"sec"); var inter=setInterval(function(){ var l=ws.socket.dSnd.length; print("t",getTime()-t,"l",l); if(l===0) clearInterval(inter); },100); // ws.send("Hello from Espruino!"); });_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v95.155 Copyright 2017 G.Williams Espruino is Open Source.

I hope we can raise this upload speed limit I am reaching.
@Gordon, it looks like the chunk size you mention 256 bytes every 200ms, that's where my ~1kb per second comes from.
@ClearMemory041063, I tried your code, but it runs after 2 steps in a "Execution Interrupted New interpreter error: LOW_MEMORY,MEMORY".
There is another strange thing, drain get called one more times after res.end() has been called.
Here's the code that looks into the dSnd, 12.5sec for 15ko :var n = 5, chk=3*1024; var tdata=new Uint8Array(chk); var i; for(i=0;i<1024;i++){ tdata[i]=0x30; tdata[i+1024]=0x31; tdata[i+1024*2]=0x32; // tdata[i+1024*3]=0x33; // tdata[i+1024*4]=0x34; }//next i function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); var t=getTime(); res.on('drain',function() { print("n=", n,"t:",(getTime()-t).toFixed(3),"sec"); if (n===0){ res.end(); clearInterval(inter); print("end n=",n,"t:",(getTime()-t).toFixed(3),"sec"); } else { res.write(E.toString(tdata)); n--; } //end else });//end opr inter=setInterval(function () { console.log("--t:",(getTime()-t).toFixed(3),"res",res.dSnd.length); }, 100); }//end function require('http').createServer(onPageRequest).listen(80);_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v95.23 Copyright 2017 G.Williams Espruino is Open Source.

@ClearMemory041063, I am surprised it goes a bit faster on your setup. I still got 17 sec for the 20kb, when I tried the two programs you posted. I tried with/out AP/station, no change. What version of espruino are you running ?
The only change I did was 5*4kb chunk, instead of 4*5kb chunks, as the latter stopped after n=3 (I guess a memory shortage).var n = 5, chk=4*1024; var tdata=new Uint8Array(chk); var i; for(i=0;i<1024;i++){ tdata[i]=0x30; tdata[i+1024]=0x31; tdata[i+1024*2]=0x32; tdata[i+1024*3]=0x33; // tdata[i+1024*4]=0x34; }//next i function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); var t=getTime(); n=5; res.on('drain',function() { print("n=",n,"t:",(getTime()-t).toFixed(3),"sec"); if (n===0){ res.end(); print("n=",n,"t:",(getTime()-t).toFixed(3),"sec"); }else { res.write(E.toString(tdata)); n--; }//end else });//end opr }//end function require('http').createServer(onPageRequest).listen(80);_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v95.23 Copyright 2017 G.Williams Espruino is Open Source.

@ClearMemory041063, not sure I understand correctly, yes I tested with an arduino program flashed on the esp8266. With arduino, I believe there is no other way than to flash my program in there.
-
I am in the first case: Esp8266 with Espruino flashed into the Esp8266. By marshalling data, I assume you refer to the E.toString. It's not much different without marshalling. The loop finish in only 13ms with a straight string (instead of 26ms for uint8array), but the 5kb of data still make 5 seconds to finish loading in the browser, in at least ten pieces :
var data=""; var chk=1024; for(var i=0;i<chk;i++) data+="0"; function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); var n= 5, t=getTime(); for(var i=0;i<n;i++) { res.write(data,'binary'); print("t:",(getTime()-t).toFixed(3),"sec"); } res.end(); } require('http').createServer(onPageRequest).listen(8080);_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v95.23 Copyright 2017 G.Williams Espruino is Open Source.

Is it possible to flush this buffer to be sent immediately somehow ? or get called until the buffer is really full ?
As if it is making an unnecessary break before each send. If I reduce the chunk size from 5kb to 256bytes, the average speed is dramatically decreased.I can't send 20kb in one go, I get "New interpreter error: LOW_MEMORY,MEMORY". If I send only 1 chunk of 5bk, it still takes 5 seconds even straight away without ondrain:
function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); var n = 1, chk=5*1024, t=getTime(); res.write(E.toString(new Uint8Array(chk))); res.end(); } require('http').createServer(onPageRequest).listen(8080);It actually seems hanging few seconds before sending anything.
-
You mean there is no work around or better way to send faster on espruino ?
To download its usable 3 mb of data, it would take ... 50 minutes. :(

Hi all,
I am working on a webserver using espruino and the esp8266, to store sensor data in the flash, and serve it to a web browser. But the network seems very slow, e.g. about 1kb per second, depending on the size of each write, much slower than when using Arduino. In this example, it takes 15second to serve 20kb :function onPageRequest(req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); var n = 4, chk=5*1024, t=getTime(); res.on('drain',function() { if (n==0) res.end(); else { res.write(E.toString(new Uint8Array(chk))); n--; } print("t:",(getTime()-t).toFixed(3),"sec"); }); } require('http').createServer(onPageRequest).listen(8080);_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v95.23 Copyright 2017 G.Williams Espruino is Open Source.

Thanks a lot Mabe for all your replies. I learned a few things, but honestly, I still feel a bit lost between builds, flash maps, etc.
My context, my current project actually run on my esp12-4mb with the basic 512/512 build. I use 8 modules, executed from flash, with FlashString (http://forum.espruino.com/conversations/290975/) and it's homemade IDE plugin (http://forum.espruino.com/conversations/313069/). I was trying to figure out if I can run it also on other configurations/builds of esp8266, and how to save and execute code from flash in these.It seems there is 1700 blocks no graphics in the 4mb combined build from http://www.espruino.com/binaries/espruino_1v95_esp8266_4mb_combined_4096.bin.

It was 16kb of minified code I uploaded and tried to save.
This is the output I get from the "4mb combined", 1700 blocks and no graphics:

Thanks again Mabe, for your reply. I made a copy/paste mistake earlier, now it's updated.
The esp8266 4mb not combined version (found here) get me :

Using the 4mb combined, from the WebIDE, I managed to upload 16kb of code, 4kb by 4kb, and the total took 1300 blocks, and it can't be saved with save(), too big :

Thanks @MaBe for your reply, Things are ... more confusing now :P
Do I understand correctly, there is 3 different builds for esp8266 ?1 / build 8266
found here : http://www.espruino.com/binaries/espruino_1v95_esp8266/. I guess it's the one decribed by this file : https://github.com/espruino/Espruino/blob/master/boards/ESP8266_BOARD.py. Has a 1700 vars and no Graphics. Available free flash total is 3mb+40kb, the 40kb are under 1mb usable to run modules from flash with E.memoryArea(). This is the build I usually use, with no problem. I install it with :python esptool.py --port COM20 --baud 115200 erase_flash python esptool.py --port COM20 --baud 115200 write_flash --flash_freq 40m --flash_mode dio --flash_size 32m 0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.binand get

I install it with the exact same command line, maybe it is not correct ? I get a very similar result, except that when I store something in the 6 first flash pages, it get erased on save().

I think it's the one you are referring to. is it described somewhere ? It has 1700 vars, no Graphics. I used the "4mb-c1" you posted in the other thread, and it worked perfectly. I understand the flash available is only the last 2MB, so not possible to have modules running from flash.

How is it possible to store as much code in them ? If I use the WebIDE, the board throw a UNFINISHED STRING when the transfer reach 10kb. I guess there is no memory for larger transfer. Is there another way ?

I see no reason why it doesn't work. Maybe the adapter. I use a nodemcu version with a different adapter (http://img.dxcdn.com/productimages/sku_406735_1.jpg)

@tempos, that's strange for the normal version, mine is also an e12. Which command line did you use for flashing the separate files ? It happens only with the v1.95 or also v1.94 or c1.93?
-
Hi, I tried with the same file and command line. I got the same problem: after I save wifi and replug, the led is continuously lit and the board only say garbage. The combined version 512 don't work at all, at least on my esp8266 4mb.
I didn't even know about this combined release, before this post. The normal not "combined" version, i.e with separate files, works much better, and I am still using it. Not a solution, but a workaround. -
Hi,
Where did you find command line addresses for the 4mb_combined ? I wanted to try it too, but didn't find the instructions.On my esp--12E, esp8266 4mb, I uses this image http://www.espruino.com/binaries/travis/master/espruino_1v95.13_esp8266.tgz, installed with
python esptool.py --port COM18 --baud 115200 write_flash --flash_freq 80m --flash_mode dio --flash_size 32m 0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.binNo problem saving code or saving wifi. Works perfectly, or almost, sometimes It freeze when I reset.

Hi,
I have a esp8266 board with 4mb. I can safely run both of these versions right ?
I know there is a difference between these two configurations of firmware. The 4MB version has additional graphics library, but only 1600 jsvars (and not 1700). This is defined by these files :
https://github.com/espruino/Espruino/blob/master/boards/ESP8266_BOARD.py
https://github.com/espruino/Espruino/blob/master/boards/ESP8266_4MB.pyBut why does the code save at a different place ? The 4MB version saved code use 16 pages of flash (64kb) instead of 3 (kb), but the board still cannot take more than 10kb at once, when I use the WebIDE. Is there a way to use these pages in the _4mb firmware ?
In the 4MB version, save() erase the 6 first pages returned by require("Flash").getFree(), I use for my custom modules to run from flash. Possibly caused by the 16pages of flash erased. But I don't understand, are they free to use or not ?
-
which files did you use ? the _4mb version does strange things for me too. The basic package (without _4mb) works better on my esp8266 4mb.
-
@Gordon, thanks for your reply. Finally v1.95 worked for me perfectly when I switched to package espruino_1v95_esp8266.tgz, I can finally run it with all my modules. The problem was only with package espruino_1v95_esp8266_4mb.tgz. I'll ask about this in the ESP8266 forum.

Thanks, very handy the .bat files. I followed the procedure with no change in speed. I placed the files in the "espruino_1v95_esp8266" directory. I ran info, erase and flash batch files.
I replugged and reflashed the WSdesp8266C. It does not go faster than before.
