Need Help With My Project
1

Hello every one

I m trying to put my project in place but still unsuccesfull.

I have read so many tutotorials and videos and still no luck .

I have connectedmy my esp 32 and uploaded an example from blynk page .Then added & created an account on blynk ,next managed to create a small widget project with a led .Finally got to the point where i cant go any further .when trying to connect to my blynk ap it says (wasnt off line ).I dont really understand what to do and how to find out if I`ve been connected to blynk app ? How to diagnose or verify it ?.

Im not __IT specialist therefore need a bit more patient :slight_smile: .
Tried even to connect to my own local server but same story / (wasnt online yet ).

Please help gain more clarrifictaion about how to diagnose problems and learn more please .

Is this really what you did, in this sequence?
If so then it would be impossible to upload a sketch that contains your Blynk Auth code, as this requires you to create your Blynk account first.

Your best troubleshooting/debugging tool is the the serial monitor. What does it show?

Pete.

Screenshots are of no real use.
Please copy/paste code and serial monitor output and paste between triple backticks, which look like this:

The “Invalid Auth token” message means that the Auth token you’ve entered into your sketch isn’t correct.
Did you copy/paste it from your email and ensure that there weren’t any leading/trailing spaces?

Pete.

Pete

Ihave noticed that what youve mentioned but am 100% sure that it was copied /paste from email and can`t see any spaces missing or anything .like that .

Well, that’s the source of your issue. As you’ve not shared your Auth code then I can’t check it.

Pete.

No problem Pete .

“Sgqi8CE1TwNDnE74BxCPBL5MFuQyJFZM”.

Here you are please .
I can always generate new one whenever find solution .

Okay, that’s a valid token for the Frankfurt server, which is your nearest Blynk server.

Try changing your Blynk.begin command to this:

Blynk.begin(auth, ssid, pass, IPAddress(139,59,206,133), 8080);

Pete.

Pete

In your sketch.
If you’d posted the code rather than a screenshot then I’d have pointed-out where in the sketch.

Pete.
