    I think I have identified a bug, in Parallax-Esp flashing.

    When I use an esp device that has a brand new flash chip (blank data)
    OR if I run this command:
    :~/Parallax-ESP $ esptool.py --port /dev/ttyUSB0 --baud 115200 erase_flash
    esptool.py v1.2-dev
    Connecting...
    Running Cesanta flasher stub...
    Erasing flash (this may take a while)...
    Erase took 43.9 seconds
    

    And then I immediately try to flash my chip with parallaxESP
    :~/Parallax-ESP $ sudo make flash
    VERSION v1.0.0-15 (2016-11-05 21:23:11 g0e22344)

    I encounter a major bug where i think the SPIFFS filesystem isn't properly created, or something.
    When I look at the debug port(DBG, GPIO2) I am getting garbage. And The esp doesn't do any AP transmission.

    I did mention before that the second part of the flashing procedure doesn't work.
    "make htmlflash"

    When i flash another program that contains a SPIFFS file system (using the arduino SPIFFS file system uploader, and then if I reflash my chip with the parallax-esp program,
    The parallaxesp program works fine. AND SO DOES THE DBG(GPIO2) output at 115200.

    To test this, I went through this procedure many times with multiple different esp devices.
    You can test it by issuing the command: esptool.py --port /dev/ttyUSB0 --baud 115200 erase_flash
    Then try to reflash with parallaxESP, if you monitor GPIO2 at 115200 baud, it should then throw out garbage.

    Can anyone confirm this problem?
    Or is it possible that my make htmlflash not working is the problem?

    Another possible bug, is the renaming feature of the module, it does not save to flash, and doesn't show up as the new name in the ap list or its network hostname.

  • How big is your flash chip? The firmware assumes a 2MB flash at present. Also, I never use "make flash". I always use the shell scripts that are in the "release" directory of the source tree. Try the "flash-all.sh" script to make sure everything gets reflashed and the settings areas get cleared.

    I have a 16meg size flash chip. I am not changing the default make settings, i figure it will just use what it needs.

    The shell scripts are causing major issues with me.
    I didn't have ZIP so i installed it.

    The esptool.py copy i have is generating errors with the sh script.
    :~/Parallax-ESP/release $ sh flash-all.sh
    Using port /dev/ttyUSB0
    usage: esptool [-h] [--port PORT] [--baud BAUD]
                   {load_ram,dump_mem,read_mem,write_mem,write_flash,run,image_info,make_image,elf2image,read_mac,chip_id,flash_id,read_flash,verify_flash,erase_flash,version}
                   ...

    I found out why, i need the esptool helper.

    I downloaded the arm release https://github.com/igrr/esptool-ck/releases/download/0.4.9/esptool-0.4.9-linux-armhf.tar.gz and put it in my /opt/parallax/bin folder.
    IT works now.

    Now the debug port (dbg gpio2) shows proper info, and the esp's AP shows in the wireless devices.
    So I had to run clear.sh and clear-ffs.sh
    This was after desoldering a 2MB flash chip on my ESP to a 16MB flash chip.
    I am guessing the new-unused 16MB flash chip contained some seriously random garbage, that caused issues.

    Hey this is MUCH better,

    The ESP now preserves my MODULENAME that I changed it to, AND the MODULENAME I changed it to shows up as the AP broadcast name. (when I search for wireless networks, it shows there)

    I noticed that when connected to an AP, the original module name shows up as its hostname still. (which is part of its mac)

    Also the DBG (gpio2) port is much more verbose than before.

    Dang, i should have used the sh script to begin with.
    Perhaps all this trial and error im going through will help create a newbie help file, hehehe...



    I am new to most of this and github...
    I never realized that most github code repositories have a "releases" tab.
    This would save me some time, I have been going about github the hard way.
    https://github.com/parallaxinc/Parallax-ESP/releases

    Now I understand why most of the things I am going aren't documented, because its not something a new user needs to do, they just need to look at the releases tab, and use all that.

    This pdf helps me immensely, i never realized this existed until about 5 minutes ago : https://github.com/parallaxinc/Parallax-ESP/releases/download/v1.0/Parallax_Wi-Fi_Module_API.pdf

    I see the pdf has the info I need to communicate with my propeller chips tx/rx lines via telnet... excellent.

  • It doesn't make sense that you had to run clear.sh and clear-ffs.sh before running flash-all.sh. The flash-all.sh script does the same thing as both of those combined plus it flashes the bootloader and the firmware. Just that should have been enough. Also, there really shouldn't be a problem with random junk in the flash chip. The esptool always erases a sector before trying to write it. I wish we could figure out what was causing this problem so I could fix it. Anyway, Parallax will be writing documentation on how to set these things up. You have to realize that you're trying to use software that hasn't yet been released so it isn't in finished form. Also, it's designed to work with a Parallax module. It's just luck that you are able to use it on your module.

    I appreciate that this is not released, and unfinished, I like to be able to help test/debug it if i get to the point that my problems aren't user error...

    AT this point, when I power cycle the esp, i get junk out of DBG, and the unit will not produce an AP.



    BUT

    You said don't use the 'make flash' method, use the 'script.sh' method, so that might be the problem.

    I cannot reproduce my first attempt at using 'flash-all.sh', I just tried after getting garbage from using 'make flash', and the script method DID fix the issue with out needing to run 'clear.sh' or 'clear-ffs.sh' No idea why my first attempt failed.

    Just about 1 hour ago I re-downloaded the parallax-esp.git and updated the entire esp toolchain and recompiled it.
    (this made my pi3 overheat, lol)

    Perhaps i messed up a parallax-esp git file, I WAS using odd permissions (sudo) and I fixed that.

    I'll keep monitoring if i can recreate it using some repeatable method.

  • Right. Don't use "make flash". I should add a note to that effect to the README file or figure out why it doesn't work and fix it. We moved to using esptool-ck because Parallax didn't want to have to require that the user have Python installed to flash the ESP.

    Pretty nifty, I can upload a propeller binary file via my browser, wireless.
    I had one over 2k, so I just.... do a few HttpRequester POST commands... to first write it to the flash file system, and then load it onto the propeller from the flash file system...
    http://192.168.4.1/userfs/write?file=blink.binary
    
    and then
    
    http://192.168.4.1/propeller/load-file?file=blink.binary
    

    Then I open telnet port 23 in PUTTY on ip 192.168.4.1, and BAM, im getting my propeller debug output, WIRELESS

    This is really excellent.

    Do you guys have any plans for this module to make our coffee too, tha'd be great. ;)

  • Hi Guys,

    I've been sticking to RC-modelflying for a long time and did almost no prop-coding.

    Now on this thread there is a lot of activity about this ESP8266.
    Here in the thread you are talking about details. (Normal what a thread does of course)
    But as I haven't been reading here for a long time it is above my head.

    Where can I find an introductional description of this "Parallax-ESP-thing" that does exist in GitHub but seems to have no product in the parallax-online-store

    best regards

    If you read the PDF https://github.com/parallaxinc/Parallax-ESP/releases/download/v1.0/Parallax_Wi-Fi_Module_API.pdf
    You can see the item number will be 32420S or 32402D. The pdf documentation has a date of November-02-2016, so ALL this stuff is new.
    Its nice that they let others in on the fun before its dun.

    I don't think its for sale YET, the software isn't done, so the hardware probably isn't also.

  • Hi Clockloop,

    thank you very much for pointing me to the PDF-File. It is what it is called
    a "Parallax Wi-Fi Module Firmware Guide"
    Now things are a bit clearer. But only a bit.

    But there is no information about the "Parallax-WiFi-Module" b]itself[/b].

    I write what I believe I have understood about this parallax-ESP-module.
    I guess my understanding is 80%-wrong. But maybe If I write that you get a picture
    of where my problems of understanding are.
    Please read and correct if something is wrong:

    The "Parallax-ESP-Module" is a WiFi-Module.
    It is based on the ESP8266-Chip.

    There is one wired interface and the WiFi-interface.

    WiFi can be set to client-mode or AP-mode. Ap-mode is insecure because it's not encrypted.
    I hope the client-mode can use WPA2-encryption?

    The different wireless modes seem to be related to low-level http-stuff
    I don't know anything about http and things like "path:handle-id" etc.
    Do I have to learn http-protocol on this low level to use this module?


    Where can I find a introductional description of the functionality?

    I mean a description like

    "With this module you can upload html-code to the memory of the module and it acts like a small webserver"

    or

    "this module allows wireless communication on the ....-level"

    or

    "this module provides a script-language that makes it easy to create devices that can be accessed via http to show measured values or interaction via simple webpages"

    From the variety of my descriptions (of what it might be) you can conclude I'm totally lost with this firmware-document mentioned above.

    So again I ask:
    does there exist an introctional description of the high-level functionality described similar to the examples above YES or NO?

    And If yes can anybody provide a link to it?



    a question to transparent-mode:

    a longer time ago I used Wixel-modules as a wirelss programming-link for propeller-chips.
    worked most of the time except very big files. With big files the propeller-tools failed to transmit the whole code.

    Will this modul be the one that allows wireless programming of the EEPROM-Chip?

    best regards

    Stefan

    You can certainly do that but it isn't the way proploader works. It uses the /propeller/load function to load a second-stage loader that then talks across a TCP connection to complete the load. It's much faster than using the /propeller/load-file function if you have large programs.

  • Hi David,

    thank you very much for commenting
    "You have to realize that you're trying to use software that hasn't yet been released so it isn't in finished form."

    I have understood that it is a product in development and that the release-date is unknown.

    Maybe I sound penetrant. (Sorry for that)
    Anyway: are you still changing the capabilities (=functionality) of this parallax-ESP-module so much that it makes no sense to describe the funcionality on the high-level?

    best regards

    I think that the functionality that is there will probably remain but more functionality is likely to be added in the future.

  • Hi David,

    OK. If you have enough of my re-asking for more details just drop a short line here or as PM and I will stop. This hasn't happened yet. So I ask:

    What is the functionality that is already in the code?

    That's because it was only intended to load a second-stage loader.

    Oh.

    I gotta say, this code so far works 'excellent', I just loaded it on an esp, and connected it to a prop that is measuring water level using etape.
    Which I am able to monitor the level using telnet and putty.
    I am using ASCII control codes to make putty display color and organize the display output, and it works great through telnet.

    Thanks for all your effort and the tech support!

    I'm glad you're having good luck with it. Let me know if you decide to try the command interface from the Propeller. It's supposed to allow a program running on the Propeller to handle HTTP requests sent over the wi-fi connection.

    I wish we could figure out what was causing this problem so I could fix it.

    Is it possible that I was encountering the bootloop issue with SDK 2.0.0?
    It seems to fit my scenario of using blank flash, or newly wiped flash, and SDK 2.0.0

    https://github.com/pfalcon/esp-open-sdk/commit/24f10eb164947fdd38b6225f72e752d5eb785391


    This was very recent also... Oct 17, 2016
     Switch to SDK 2.0.0 by default.
    
    Firmware built with SDK 2.0.0 can't be programmed to blank flash (will
    lead to bootloop), so affected parties should be prepared to flash
    esp_init_data_default.bin manually, or update their firmware to detect
    blank flash and initialize default data automatically (what previous
    versions of vendor SDK did themselves).
    


    Ok, nevermind, I see you already DO flash esp_init_data_default.bin in the flash-all.sh file.

    Why can't we delete posts anymore... it just leads to post bloat.

  • IS there anyway to set your mode to STA and your ssid/password without using the webinterface or the serial interface?

    I have had a very difficult time getting STA/AP mode to display my AP.
    In the serial diagnostic output, it says it found 1 ap, but no ap ever shows up on the networks list.
    And it continually repeats the same message, found 1ap, but the webpage never shows the ap that it found.

    Is there a way to force the firmware to start in STA mode and connect to a specific ap?
    What file would i change?


    I think I also might have found a bug.

    If you change the module name in STA mode, and try to save to flash, it will not keep the name.
    But if you change the module name in STA+AP mode and try to save to flash, it WILL keep the new name. (even if you then switch to STA mode)

    It should already do that. Once you've connected to an AP it remembers the SSID and password and connects automatically the next time if the AP is visible.

    I think I also might have found a bug.

    If you change the module name in STA mode, and try to save to flash, it will not keep the name.
    But if you change the module name in STA+AP mode and try to save to flash, it WILL keep the new name. (even if you then switch to STA mode)
    Again, I'm not sure what's going on here. I haven't seen that behavior. The settings code really has nothing to do with what wi-fi mode you're in.

    Is it possible that all the background apps and programs that are trying to connect to the internet are causing the esp to timeout for the original webinterface config page?
    (a.k.a. too many DNS connection attempts)?


    I see in the diagnostic output, that my tablet and pc try to repeatedly connect to multiple websites for all kinds of background communications..
    I know the esp has a limited about of connections it can handle...

    It should already do that. Once you've connected to an AP it remembers the SSID and password and connects automatically the next time if the AP is visible.
    not sure what's going on here. I haven't seen that behavior. The settings code really has nothing to do with what wi-fi mode you're in.

    Yea, im saying i want to change the firmware settings so when i run flash-all.sh, my esp is already programmed with its ssid and password.

    Use the flash-fw.sh script and it won't overwrite your settings or the flash filesystem.

    In fact, why not just use OTA firmware updating? I never use the batch files unless I flash firmware that doesn't work for some reason. It's much easier to just use an OTA firmware update.

    It seems I have major issues with an esp that doesn't have an antenna built in.
    I have 8 of these, and they seem to be a bad design.
    I seem to have nothing but problems with this particular version:

    But this one below works great with your software. (i have two of these, and both work perfectly)

    Which pins did you pull up or down while programming or running?

    The original modules typically need such action, more complex devboards don't...
