Instability if compilation is done under linux - no issue windows version

[treepleks]

Dear Luc,

I have cloned your code (master branch) with the aim of using/tuning it to run on a smoothieboard variant (the AZSMZ mini) which has room reserved for an ESP01 module on its LCD board. I have bought 2 ESP01 module, they have 1MB flash, I use 128KB for the SPIFFS filesystem.

I compiled your code (with arduino 1.6.7 and the last version of the ESP8266 arduino module), flashed it but I have a problem with the web pages. I can connect to the ESP access point, authenticate, and access all the various pages but the "Station" page. The ESP never serves it.

I inserted a long list of Serial.println() in the corresponding function _handle_web_interfaceconfigSTA() in webinterface.cpp and the problem occurs on the following lines:

  //revert to pure softAP
  if (revertSTA) WiFi.mode(WIFI_AP);
  KeysList.add(FPSTR(KEY_AP_SCAN_VISIBILITY));
  ValuesList.add(VALUE_ITEM_VISIBLE);

If I comment the 2 last lines... everything seems to run fine. But I cannot see why these 2 lines could generate a problem (except for a lack of RAM issue).

Any idea ?

PS: I see you have also a specific Repetier firmware that communicate with the ESP module. Would it be possible to know what this firmware brings compared to Repetier ? If it's significant, I may upgrade Smoothieware in the same way.

Ok I can reproduce issue if I comment 2 features :

//MDNS_FEATURE: this feature allow  type the name defined
//in web browser by default : http:\\esp8266.local and connect 
//#define MDNS_FEATURE

//SSDD_FEATURE: this feature is a discovery protocol, supported on Windows out of the box
//#define SSDP_FEATURE

Good. Thanks for your help.

I posted an issue on ESP8266 for arduino as there are visible differences between the Linux and Windows ESP packages (eg. different versions of include files in the tools folder).

OK - I have changed the label to SDK issue

[luc-github]

I have changed title to better reflect issue

Hi, I do not know if you want this here, or somewhere else? This module arrived yesterday: http://www.ebay.com/itm/271981074883?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

When I connect it to arduino, it says ESP-12E,4M so then it seems like the flash is ok on this module

[luc-github]

It is not an hardware issue but seems module issue as it happen only on linux version It may be a compilation problem as core is a zip file identical for all OS just compilation tools (binaries / libraries) are different according the OS they are used

[treepleks]

Would you share your code ? It would likely be trivial to integrate it (at least the SD recording ability) here.

I added to it the ability to record to SD and work with EEPROM, but I use Marlin and RAMPS.

I guess you all know this, but I found a simple way to find Flash size using the Arduino IDE - added it to the RADDS WiFi documentation: http://doku.radds.org/dokumentation/other-electronics/wifi/

A question: is there a sample showing the settings for connecting the ESP8266 to en existing WiFi network, mode, SSID, Password ?

[luc-github]

there is a screenshot of station tab in readme, is that you are looking for? you also can use serial command to set parameters and display current config

[mundsen]

After spending some time learning how to do the setup, I now can confirm that the modue I ordered from ebay works fine without any soldering, and the one I got have 4M Flash. http://www.ebay.com/itm/271981074883?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

My wifi guide ready soon: http://doku.radds.org/dokumentation/other-electronics/wifi/

[luc-github]

Good - if 4M you are sure you won't have any limitation

I think I will do a new release next week as thanks to @treepleks code has several fixes in master now, and it is definitely better than beta1, also has more feature and linked to identifiable stable 2.0.0 of ESP8266 development module

[mundsen]

What settings do I need to enable in Repetier Firmware to get it communicate with the WiFi module? Bluetooth serial + baudrate? JSON..? - solved, my baudrate in Repetier was wrong

[luc-github]

@mundsen it depend where you connect ESP module, if you connect in RX1 TX1, repetier need to use Serial1 So you need to compile repetier with #define RFSERIAL Serial1 but it is not really ease of use so I did some modification in my flavor of FW to not have to - for me it is in printer menu, but my repetier version has a very different UI and some feature difference compare to repetier https://github.com/luc-github/Repetier-Firmware-0.92 (092.3 based) 0.92.6 is https://github.com/luc-github/Repetier-Firmware-0.92/tree/0.92.6-sync but I think will become https://github.com/luc-github/Repetier-Firmware-0.92/tree/0.92.8-sync very soon Originaly ported for Davinci printer, I also use it on my Due/RADDS/GLCD printer

for Marlin I never had time to check yet

[luc-github]

Now 2.1.0 stable is out (http://arduino.esp8266.com/versions/2.1.0/package_esp8266com_index.json) - may be issue is solved

[luc-github]

seems 2.1.0 do not solve issue https://github.com/luc-github/ESP8266/issues/80

[luc-github]

Ok it is actually several missing FPSTR that generate the crash - weird crash happen only when compilation is done under linux and not under windows
