Yea, for sure! Thanks for coming back around the confirming the issue and the fix for the rest of us!
Glad to know the OVA was of some assistance! =]

Sorry for the delay... my wife surprised me with a mini vacation after Christmas with the understanding - no computers were allowed.

I got it working... here are the results.
My program runs fine on your environment, as well as PlatformIO environments and on the Arduino environment versions too... IF... I include a call to espconn_init().

Some time ago, I read one post on another thread mentioning this method, but adding it to my projects gave compiler errors. So I discounted the post as being for an older version. The thing is... this call wasn't needed in SDK 2.2 and earlier.

Anyway, I was working backwards though the available Espressif codebase from the espconn_regist_disconcb() method and ran into... wait for it... espconn_init() in an Espressif C file. But it had no corresponding H file declaring it. I simply added my own declaration...

extern "C" void ICACHE_FLASH_ATTR espconn_init(void);

and added the call in my startup code... and Wham, bam, thank you mam! My disconnect callback started getting called and all was right with the world.

Thanks for your help!

Ohh Yeea yea yea.. DuuuR!! I think its the default kali password like root or toor.. my bad.. let me test.. brb
*Edit* Yep, this is set to

osboxes.org <--- same as username. This is the default from osboxes.org (of course)

For someone that spent the last twenty years of my career tied to fiber, this feels like using smoke-signals. For S&G, I started a download at home while all the tourist and locals are at home for the holidays... projected to be three+ days to download. Drove over to the library... and seven whole minutes to download. It's all GOOD! Next...

Fortunately, I had VirtualBox loaded and a couple of Windows VM's that I know work.
Imported just fine.
Trying to boot up, it complained about the NIC card, but apparently that is a Virtual Box setting and it let me swap that over.
Next it complained about my USB. It let me select the USB 1.1 and didn't complain (I have 2.0 and 3.0 ports on my desktop) Hoping if that is a problem, it'll let me upgrade them by detection and download over the Internet once I get in.
It booted up and I'm now at the login... I tried all kinds of accounts/passwords... , sudo, su, password, passW0rd, pw, AgentSmithers, Inquisitor... and looked on the Internet for defaults for CentOS. Those didn't work either.

Seems like I'm close.

P.S. - I came from a Microsoft Windows development background and use the Arduino IDE for the MPU's... IOW... I barely know what a make file is... and have never knowingly opened one up. Even my baby step into PlatformIO have sheltered me from those evil files. If it's not too much trouble, a small project with make file would be great. Although, I probably could dig out the example projects from Espressif.

Oh... and no rush. Don't let this interfere with your holidays.

Sure! That would be very helpful. At the very least it would confirm whether my program above works on pure Espressif SDK > 2.1. It would also confirm my suspicions that it's the Arduino libraries riding on top of Espressif SDK > 2.1 causing the problem.

Thank you for your help.

Thank you for responding. I first posted this problem back in 2017 and you're the first to respond. This thread is a re-posting with as simple an example as I could create hoping someone would take pity on me.

http://www.liot.io/media/liot_esp8266_e ... erence.pdf

In 2.2 I think if my memory serves me correctly they add a few new API commands for the 802.11 to adjust power savings to some extent. I would add those API's into your AP init code and toggle with those Params and see if it resolves your issue. If it does post back here so everyone else can see the result!

Last week in desperation, I did resort to looking for old documentation. I did not find any. Must have had the wrong search terms. So this document was a great find. Since your post, I have been scouring through the differences and trying various parameters. I would not have even tried things related to power settings. At this point, I'd try anything.

I think what bothers me the most is that no one else has this problem. I am beginning to think it has more to do with the Arduino implementation riding on top of the Espressif code base. I have tried...

A totally NonOS version using VSCode/PlatformIO which is at 2.1.0. It works fine, showing the espconn_regist_disconcb() being called.
Unfortunately, I can't seem to find a way to make PlatformIO use a newer SDK. So, I have not found a way to test the above code with a true, unmodified SDK like 3.0+.
I have tested it with the NonOS modified version in Arduino IDE that uses SDK 1.5 and again, it works fine the same as above.
As soon as I move to the newer Arduino IDE versions that uses Espressif version 2.2 through 3.0 SDK, it serves up the web page five times and fails on the sixth request. The Browser shows a "This site can’t be reached The connection was reset."

Currently, I'm now focusing on what settings the Arduino version modifies that might cause this to fail. But again, I'm stuck with the lack of complaints on the Arduino forum. There differences seem to be that all their code is based on lwIP while the above code avoids even using that 3rd party library.

Thanks again!

I recall a Wifi issue for myself with SDK 2.1 to 2.2 back when I upgraded. It had to do with the sleep function or configuration APis of the Wifi, (They might have just been added in that SDK version 2.2) I think in 2.1 there may have been left over Init Params that may jack with the 2.2 wifi Params but I don't have the technicals on it. From what I recall I was using pfalcon's github setup and when I moved from 2.1 to 2.2 it broke my station code. I remember what I did was I opened the PDF for the "ESP8266 Non-OS SDK
API Reference" for 2.2 and compared it to this below (version 2.0, look for 2.1 if you can, I couldn't find it online)
http://www.liot.io/media/liot_esp8266_e ... erence.pdf

In 2.2 I think if my memory serves me correctly they add a few new API commands for the 802.11 to adjust power savings to some extent. I would add those API's into your AP init code and toggle with those Params and see if it resolves your issue. If it does post back here so everyone else can see the result!

Also, do a full memory purge with esp_tool erase and reflash your 'esp_init_data_default' files to make sure everything is clean.

That should get you back and running.

Good Luck!

Broken Code with SDK 2.2 and newer

2021-11-29T00:52:35+08:00

The following code used to work great with SDK <= 2.1.0.
Can someone tell me what modifications I need to make to allow it to work with SDK > 2.2 and newer?

It is a simple Testing Web Server (only 230 lines). In old SDK (and current manual) espconn_regist_disconcb gets called and all works great. In 2.2 and newer it never gets called and fails after the 5th browser refresh.

Thanks.
