i dont see you running WiFi.begin()?

[mlbranchus]

TonTon, Thanks for the swift response. Unfortunately I'm fairly new to programming, basically I follow examples to learn. Ok. I inserted wifi.begin() in void.loop() but got a scope error. I tried brackets without success. So, I'm going to need help to do anything to fix this mess. Thanks

[tonton81]

it has to be in your setup()
WiFi.begin(“SSID”,”PASSWORD”);

[tonton81]

note the upper and lower case “WiFi”, must be exact

[mlbranchus]

TonTon, I installed the fix, restarted IDE and still got status code 21. Shortly thereafter I got a halt. Is there more to this? Here is the fault info. Thanks, Mike

[mlbranchus]

TonTon, BTW...I entered my router SSID and PASSWORD. Mike

[beicnet]

You also need to #include wifi libraries too! Like this #include "ESP8266WiFi.h"

[mlbranchus]

TonTon, BTW...I entered my router SSID and PASSWORD. Mike

[mlbranchus]

Which wifi libraries need to be included? Mike

[beicnet]

As I wrote before above at the top of your code:
#include "ESP8266WiFi.h"

[mlbranchus]

TonTon and beic, I've added #include ESP8266WiFi.h but I'm still getting fault code 21. Mike

[beicnet]

Did you include ESP8266 Arduino core to your references?

[mlbranchus]

beic, I don't know. I don't think so. What is the specific name and where is it located? Thanks, Mike

Open the Arduino IDE and go to:

File > Preferences > Additional Boards Manager URLs and then add this line:

http://arduino.esp8266.com/stable/package_esp8266com_index.json

close the IDE, then reopen it.

After that go to the Tools > Board Manager, find ESP8266 Community and install it.

[mlbranchus]

Beic, I already had it installed in prefs and updated as ver 2.3.0. Next? Mike

[beicnet]

I see, you need to remove that line in your code WiFi.begin("annwyn","pirate9d"); //ENTRY HERE , #include <ESP8266WiFi.h> and all configurations/settings has to be done in the config.h.

You just need to follow the Adafruit tutorial included at a top of your code.

[mlbranchus]

TonTon told me to add that line of code.

[tonton81]

sorry i was not aware the library had a separate file for that, another reason i hate adafruit libraries

[mlbranchus]

Ok, So all of that code belongs in config.h instead of .ino?

[beicnet]

No, there is two file one is .ino and the second is .h, your settings are located in the .h file, there you need to setup your credentials and connection type.

[mlbranchus]

Yes I know that. All of my credentials and connection type are already in the .h file.

[mlbranchus]

Ok. Everything is back to where it was before. And the code 21 fault is still there! Mike

[beicnet]

What line gives you the fault code? Can you post a screenshot?

[mlbranchus]

The serial monitor shows status 21...thats the fault code

[beicnet]

Just that outputs? Nothing else?

[mlbranchus]

The first 2 show what I get when output fails. the third shows what serial monitor reports as it is running. the fourth is just what the status code is i.e. status 21 That's all I have.

[beicnet]

Can you post a screenshot of it?

[mlbranchus]

Im going offline in 40 minutes. I'm going offline for 3-4 hours. Thanks Mike

[mlbranchus]

The first 3 ARE screenshots of it! This is all of the imformation about it that ESP is providing. As I said , the first two screenshots are the error when the connection fails The third screenshot shows the running serial monitor while the connection is connected. But the third shows "status 21" every four cycles.

Hi guys. Thanks for the work on this. Have you come with any ideas to fix this fault code? Mike

[beicnet]

I don't see / have any screenshots from you!

[mlbranchus]

We're having a serious failure to communicate here. I've sent you all of the screen shots that I have. I've sent the beginning and end of the reset comprising of the first and second screenshot(s). I've sent a screenshot of the running serial monitor shgowing status fault 21 compriising screenshot 3. All three were sent via email. Did you receive them? Mike Is there a specific screenshot that you're looking for?

[beicnet]

Screenshot is when you press the "Print Screen" button on your keyboard and then save it in mspaint as image and you attach that image to this post!

[mlbranchus]

I know what a screenshot is! I took 3 of them several times for you. I just took another one for you just a few minutes ago.

[beicnet]

As you can see, there is no images present in this entire post!

[mlbranchus]

what about in the email?

[mlbranchus]

No it's not

[beicnet]

Just drag and drop your images here!

[tonton81]

jeebus, this “issue” is bigger than an average forum topic lol

[beicnet]

🤣

[mlbranchus]

I've sent MANY email messages with screenshots.

[mlbranchus]

LOL. driving me insane.

[beicnet]

So, did you made already account on Adafruit IO, just a simple question

[mlbranchus]

I will provide whatever you want. Do you want email? Do you want Github? Just tell me and I'll do it.

[beicnet]

Github

[mlbranchus]

So...how do I open the GitHub information?

[beicnet]

just upload the images to https://imgur.com/ and paste links here...

[mlbranchus]

Is this a joke?

[mlbranchus]

If we could define the where and what I think we can get to the how. The issue is that the connection software fails to reset automatically. I have to manually reset each occurance.

[beicnet]

Not a joke, if you don't know how to attach images here, then I can't help you, another thing, this is not a support forum, it's a core development branch, so, here you will not get any help regarding you sketch.

You basicaly need to ask your questions on your board manufacturer and code sample page.

And it's located here.

Regards

[vdeconinck]

@tonton81 and @beicnet , I know how it feels, I'm always tempted to help users too, but I've been reminded in the past (and rightly so) that this is a tracker for issues in the ESP8266 core for Arduino IDE, not a forum for tracking user errors, and certainly not for teaching people how to attach an image to a comment.
Per https://github.com/esp8266/Arduino/blob/master/POLICY.md , I think the best is to move that discussion over to esp8266.com or stackoverflow and close this issue that is currently just generating spam.

[beicnet]

@vdeconinck Yes, thats the reason for my last comment to him and it's not that I wont help!

[devyte]

Alright, enough.
@mlbranchus please request help at a community forum, and discuss there. If you reduce your problem to an issue in the core code hosted in this repo, please open a new issue and provide the requested details, including an mcve sketch. Keep in mind that issues with 3rd party libs such as Adafruit are NOT covered here.
