different ESP board diferent web server behiavior #1889

mkeyno · 2016-04-09T10:20:10Z

Hi dear @igrr
I run the modified webserver example of last stable code in 3 different ESP board, there is couple of pages on flash but strange is whereas speed and performance is good on NodeMCU(ESP-12 core) module but for the ESP-01/1MB flash , ESP-07/56KB flash modules most time pages not loaded or partially loaded , it seems same code run on the ESP-01/1MB flash , ESP-07/56KB flash so slowly regards to ESP-12E core , I choose different Settings in IDE for ESP-01 & ESP-07 (such as Generic ESP, ESPdunio , Sparkfun ESP thing ,...) . I can program and upload data for couple of setting and not for others , is there any special setting for such module ? how could I have same performance like ESP-12E?is this probably related to @luc-github issue

ESP-xx modules do not have any differences except for their physical layout and antenna options. If something works on one module but doesn't work on another, you might want to check if

the misbehaving module is adequately powered and decoupled
the code is compiled for the correct flash size. AFAIK there are no 56kb flash modules, so perhaps you need to double-check that specification
erasing flash completely (using esptool.py or esptool-ck) may help remove corrupted SDK config

mkeyno · 2016-04-09T21:06:10Z

thanks dear @igrr but why module has different behavior when we select different Settings in IDE (name of board , speed of flash , reset method, flash size,...) why each vendor define it's own Settings in IDE? what's the benefit of that ?
so sorry for this much questions

WereCatf · 2016-04-09T23:49:12Z

@mkeyno Because some manufacturer uses 512KB flash, another uses 4MB flash, some have cut off the two pins that go to the flash so it can only be driven in DIO-mode, some have all the pins connected, allowing the flash to be driven in the much faster QIO-mode, and then there are the pin-definitions, like e.g. on the Nodemcu the pin that's marked as D0 is actually GPIO16, whereas on another manufacturer's board a similarly-named pin D0 could be some entirely different GPIO-pin underneath, or they may use some other naming-scheme altogether -- these board-specific pin-definitions are there for ease-of-use reasons.

Basically, a lot of settings that vary between manufacturer to manufacturer.

mkeyno · 2016-04-10T04:52:23Z

thanks @WereCatf for your answer , so you were saying the only main different is the flash size & flash connection type(hardware connection) , other should not has much impact on module programming , however I was wondering if you have any suggestion for ESP-07 IDE setting

WereCatf · 2016-04-10T06:11:36Z

There is no such a thing as an ESP8266 with only 56KB Flash, you probably mean 512KB. Setting IDE to generic ESP and flash-mode to DIO should work every ESP-module out there, you just have to make sure the flash-size is correct. In your case, it might be a good idea to format your SPIFFS, too, to make sure it's not corrupted.

mkeyno · 2016-04-10T08:40:51Z

thanks @WereCatf , I ran some test to find correct size of flash and SPIFF, and it run now but somethings new come up , I put about 200kb pages on the SPIFF and simple webserver to serve those pages , but when I connected to AP, it shows nothings , no request form browser send to AP node whereas my laptop correctly connected to that AP, I've tried with other browser but nothings happened, it seems AP can not received any header request from browser whereas with example of library , node received all request form browser , I might add my sketch totally work with all browser when I use NodeMCU

module ESP-07
flash size 1mb , SPIFF size 512 or 256
sketch size 270kb

So, the same sketch, with no modifications to it, works correctly on the Nodemcu but not your ESP-07?

I see you are using Arduino IDE 1.6.7, are you also using an older version of the ESP8266-stuff for Arduino? Perhaps you could try installing IDE 1.6.8 and grabbing the latest stuff from here and testing if it works any better?

If the answer to the first question is yes, and it doesn't work any better with IDE 1.6.8 and latest stuff from here, then it sounds like a bug in the SPIFFS-library or the webserver-lib.

mkeyno · 2016-04-10T11:41:17Z

dear @WereCatf I ran another test , I upload the same file on SPIFF and sketch with two same module (nodeMCU) but supersized when one module work fine and other not , one get any request from browser and respond fast and other seems dumb to any browser request , how is happened ? when I connected to AP node I set the both network on home type in windows 7 64x

So, you didn't try with newer IDE and ESP8266-libs?

mkeyno · 2016-04-10T11:51:24Z

not for IDE but my ESP8266-libs is the last one

mkeyno · 2016-04-10T12:00:01Z

I did , I test it with Arduino 1.6.8 hourly nights , the same issue , it is possible somehow my node not registered for windows 7 and no request pass it to my AP node

mkeyno · 2016-04-10T12:45:19Z

dear @igrr do you have any idea why same sketch and file have different behavior for same module

mkeyno · 2016-04-10T17:05:54Z

dear @igrr & @WereCatf I set debug level to "All" in Arduino deice setting (Generic ESP8266) but what is out come is the endless following info, I don't know why my code work fine with one module and respond browser request but other not or partially catch the browser header request

You are absolutely certain that your module is getting enough power? Unstable power-supply or too little power could also cause something like this, I guess. I do not have an ESP-07 to test with.

mkeyno · 2016-04-10T17:38:37Z

I've check with NodeMCU, one module work and respond find and other not, can you kindly advise me how can enable debug on nodeMCU just like the generic esp8266 , it seems this option not available for nodeMCU

WereCatf · 2016-04-10T17:41:39Z

You can use the same generic settings for the Nodemcu-kit as you use for the ESP-07, except set Flash to 4MB - size. Ie. flash size to 4MB, flash-mode to DIO.

no change , I'm so confuse and exhausted, how come pair of same module behave differently ?

Did you check the power-supply you're using for the ESP-07?

mkeyno · 2016-04-10T17:58:19Z

right now I work with 2 pair of nodeMCU rev 1conected to my laptop USB

WereCatf · 2016-04-10T17:59:01Z

I didn't ask about your Nodemcu, since that's working. I asked about the ESP-07.

mkeyno · 2016-04-10T18:01:23Z

when I have continue issue with my ESP-07 I've change it with nodeMCU but code work with one and not work for other

mkeyno · 2016-04-10T18:04:17Z

@WereCatf I got some info , in my code there is function which is restore some parameter from EEPROM , when I disable it the module work fine, the restore parameter has not to do with wifi parameter and setting , how this affect the wifi performance

the module that already work has preset EEPROM, but when I program my code on new module there is no preset EEPROM data , how this brutally affect the module performance , dear @WereCatf can you kindly check my setup function

WereCatf · 2016-04-10T18:39:43Z

There are no such functions in the library as EEPROM_Read and EEPROM_Write, are those something you've written yourself?

mkeyno · 2016-04-10T18:48:26Z

yes buddy
void EEPROM_Write(String s,byte from, byte to)
{
for (byte i = from; i < to; i++) EEPROM.write(i, 0); //earase
for (byte i = from; i < from+s.length() && i < to; i++) EEPROM.write(i, s[i-from]);
EEPROM.commit();
}
String EEPROM_Read(byte from, byte to) { String s=""; for (byte i = from; i < to; i++) { byte c=EEPROM.read(i); if(c>31 && c<128) s += char(c); } return s; }
