Simple example

[Johnep101]

I only have iOS devices (😒) so is there a really simple example somewhere that allows me to connect a device to the server without having an app to connect the device to the local WiFi router and cloud server?. I just want to get a device (esp32 dev board) up and running and get data onto the Blynk dashboard. Something like the standard Blynk.begin(auth,said,password) method? Thanks

Install the 1.0.0beta3 library and use the ESP32 WiFi example.

In the Web portal, add a template that's based on an ESP32 board, then create a device based on that template. The Template screen will give you two lines of firmware configuration, copy these and add them at the very beginning of your sketch. In the Device > Device Info screen you'll find the Auth Token (left hand column, half way down) click on the green square to the right to copy this to the clipboard...

and paste it into your sketch in the normal way.

Hi Pete, Many thanks I was over complicating things thinking I needed to add the BlynkEdgent.begin(); and BlynkEdgent.run(); with all the associated libraries. However :- having copied and modified the ESP32_wifi example and adding the lines you suggest the device hangs up at Blynk.begin(auth, ssid, pass); auth is from the device as you suggest and ssid and pass are my normal values. The sketch came from Arduino>Examples>Blynk>Boards WiFi>ESP32_WiFi I note that there is a Arduino>Examples>Blynk>Blynk.Edgent library with an ESP32 example which is the one I started with, but I just can't modify this over complex example.

Hi John, what do you see in your serial monitor?

Pete.

Hi Pete, this is what I get:- 13:31:14.879 -> +Fd⸮⸮/⸮bA&P⸮2⸮L⸮⸮⸮starting 13:31:15.184 -> [42] Connecting to Sol2.4 and the section of code:-

Serial.begin(9600); Serial.println("starting"); Blynk.begin(auth, ssid, pass); Serial.println("Connected");

[Peterkn2001]

Looks to me like your WiFi credentials are incorrect, as you'd expect to see some sort of connected message and a a local IP address before attempting to connect to the Blynk server.

Hi Pete, I checked to credentials and they looked fine so I tried another board, that didn't work either so I reverted back to an old auth code I had an app for, that didn't work either. SO I rechecked the credentials and sure enough the wifi SSID was incorrect! so much for men checking things. I then got the start up banner and the error invalid Auth Token, I remember your earlier comments on this, using the new server doesn't work. so went back to the original code and happiness around I have data on the server! (Just need the IOS app now Dmitriy!) So, Again, Pete my grateful thanks for your work!

@Johnep101 iOs app is planned to be released on Friday.

[Johnep101]

Brilliant thank you 👍

[Johnep101]

On my device dashboard I can see data coming in but on the device info panel it says status offline. Is this because I do not have an associated app yet?

[doom369]

@Johnep101 you need to refresh the page. That's a bug, it was fixed. Will deploy it soon.

[Johnep101]

Ok it's just switched to online 👍

[Johnep101]

Many thanks and thanks for the opportunity to trial this incredible project

[doom369]

@Mark-Pan please add this answer to the docs for "static provisioning (old blynk way)" so we don't miss it.

Hi Dmitriy, Sorry for contacting you directly but I think there will be a lot of confusion when you go public with this new Beta. Firstly you need a whole bunch of new examples, the current ones just will not work and the the two given ones, although complete, are way to complex for most builders. Secondly you need a new repository on GitHub - completely separate from the current Blynk. You also need to divorce, COMPLETELY the old library and the new Beta library. It is very difficult to maintain legacy projects and new projects. Just completely separate the two. Below is a simple device that works, demonstrates input / output and I’m sure will help newbie builders like myself.

I think you have a fabulous system and being a retired engineer I’m happy to help develop examples for you. I really want this system to work so I have copied a simple sketch below which might help newcomers.

Love the dashboard concept!

You also need to divorce, COMPLETELY the old library and the new Beta library.

I think in the same way. However, I not the only person who makes the decisions. So many decisions are still not final and under the discussion. We'll see. But we have to release what we have, otherwise, we would delay the Beta more and more.

I think you have a fabulous system and being a retired engineer I’m happy to help develop examples for you.

That's really cool. Maybe @vshymanskyy could somehow guide you here. And thanks for the shared example

[Peterkn2001]

I'd agree. The current Blynk community forum is plagued with issues caused by people downloading the beta libraries. Even the new Beta-3 library isn't the solution to anything other than the failure to connect issue.

These are two separate products and need to be treated as such.

Pete.

@doom369 Any updated timeline on this, using my old Android tablet is driving me nuts!

Given up on Android 😱😱😱

Happy Easter!

@Peterkn2001 It has too many bugs :(. So we'll need few more days. @eepetrash FYI
