Question Regarding Migrating to Blynk 2.0

Solved
,
1

Hello Everyone,

Trying to migrate a project to the new Blynk and having a bit of a time understanding how to integrate Blynk.Edgent and its provisioning into my project.

I can get the example sketch working for Edgent, and I can provision it through the new Blynk App and connect it to the template, all good. What I don’t understand is where I am supposed to put my program into the Edgent example. I would like the device to come up in provisioning, be provisioned into the template and with the required network credentials and when it reboots, reboots with my sketch, including the needed add-ons to have OTA updates and all the other new goodies work through the Blynk Cloud console.

I’m not sure if I should upload my code, it is fairly long. I’ve experimented with trying to add my sketch to the .ino file of the Blynk.Edgent example but I haven’t had success yet so I figured I would reach out here and make sure I’m not missing something obvious. The documentation isn’t clear (from my point of view) on how to add your sketch to the device, the provisioning aspect is clear and straightforward.

I’m using an ESP32-CAM AI-THINKER.

Thanks in advance for your help!

That’s the way to do it.

Thanks for the quick reply Pete.

As a quick question, my sketch in Blynk1.0 used the WiFi.h library, which requires me to have my ssid and pass as chars, but since I want dynamic provisioning I don’t want any pre-loaded stuff in the sketch. Most of my errors seem to involve this type of problem. requirements to be declared that are taken care of in provisioning but the libraries need for compiling.

Am I better off trying to re-write the sketch without using these libraries? Also, do I need to include the BlynkSimple library in my sketch or does Edgent take care of all these functions? The documentation is not clear.

Thanks again.

I’ll be away from my computer most of the day but will try and keep up to date on replies. Worst case I will post updates tonight.

Played around with this most of the weekend, not a lot of luck.
Does anyone have an example of a program they have gotten to work while also using Blynk.Edgent?
I can’t seem to get my program to work with it and the documentation is very unclear on most of the new Blynk2.0 stuff (I get that it is new and they are still working on it but my god is it making it fun to try and get things working that aren’t super, super simple.)

First of all, if your sketch is big and complicated, it’s not mandatory to integrate with Blynk.Edgent. Especially if it’s just a single device of this type.
Just add Template ID and static Auth Token on top of your existing sketch and you’re good to go.
More on migration: Migrating to new Blynk - Blynk Documentation

Thanks for the reply!

I know its not mandatory, but ultimately I’m working on turning this project into a saleable product and the provisioning/deployment and OTA aspects of Edgent are just too tempting to ignore. I was hoping some people on here had some luck integrating it and I could browse their code and see what I was messing up.

I guess I’ll try and get it working with a static auth token first and then play with Edgent. The datastreams are also not clear to me but thats likely because I haven’t had a chance to actually use them yet.

9

Wanted to give another update. I managed to get my sketch to compile (still not working but baby steps) with these steps:

  • get rid of my Blynktime timer line, it is in one of the .h files and that messes it up.
  • leave all my original code in place, no commenting out of the wifi ssid, pass, auth, etc.

Now the problem I have is the device seems to boot straight into my code, not the Blynk Provisioning section but also refuses to connect to the cloud. I can get the example code, and other randome Blynk examples to connect to the cloud, but using the same auth token my device will not.

I’m also unsure what I am doing wrong that is causing it to skip the provisioning process.

10

Remove Blynk.run from loop. Its taken care by BlynkEdgent.run

I can see in the setup part, the serial.begin is at the ending of setup(). So you cannot see whats (errors) happening on the serial monitor before this is called.

And also blynk functions in setup before the wifi setup protocol is called in.

So i suggest you to clean up the code a bit. Keep a proper flow of the code. This may not solve the problem yet. But we can get an idea where n whats going wrong.

11

Thanks Madhukesh, I “think” I’m making some progress here.

I’m getting fewer and fewer compile errors, but still having issues, I’m at work right now but I’ve made some changes, done some cleanup and will repost with my current issues tonight!

12

So I have narrowed down the source of my compile errors.
There seems to be some sort of conflict or issue using the including #esp_camera.h in your program. As soon as I include it I get a whole host of errors, which I have included in a code block below.
Specifically, the errors seem to all point towards driver/ledc.h other than a weird closing bracket error. Anyways, all these errors vanish if I comment out the #esp_camera.h

Sorry, as one more additional add-on. This issue impacts Blynk 2.0 regardless of if you use Edgent, but the program will compile without Edgent, it will just never connect to the cloud. I have had a device connected with a simple example sketch, uploaded a working sketch on Blynk1.0, added in my template data and device name, it will upload the code successfully, connect to the internet but never connect to the Blynk server.

14

Was your previous code working with Blynk 1.0 ?
I feel there is conflict between the pins used. Cross check your pins used in the code and settings.h file. Try to compile with different ESP32 board selected (WROVER) and see if that works. And also see if the ESP32 core is updated / changed which was working with 1.0…. BTW you should be using the Blynk 2.0’s 1.x.x not beta versions.

15

Maybe posting your esp_camera.h code would be a good start, as without it the compiler messages mean nothing.

Pete.

This compiles and works fine with no errors. However, if I add in a Blynk 2.0 template ID and device name along with a manual auth token for Blynk 2.0 it will not connect to the new server. It doesn’t give any compile errors, and the serial monitor shows Blynk cloud connection failure.

Hey Pete,
The camera code is directly from Espressif and included in the ESP32 library, I haven’t modified it at all and it works fine with Blynk 1.0:

Did you try reinstalling the Blynk lib ? I had same issues when i updated the Blynk lib. Later when i deleted the lib folder and installed a fresh copy !! The errors went away and started to work as it should. This may not be the route cause ! But i suspect this.

I’ll try again.
I re-installed the library once after it seemed to get itself messed up when I first started playing with Edgent and it wouldn’t even compile the example.

I’ll delete and re-add again and see if maybe that works.

Thanks!

Nope, definite conflict somewhere in there.
I’m at work right now, and put my code into a completely fresh install of the Arduino IDE with fresh installs of the Blynk library.
As a test, I compiled the Edgent example for ESP32, no errors, compiles fine.
Then, I added just the line

#include "esp_camera.h"

and it gives me these errors:

Compilation error: Error: 2 UNKNOWN: exit status 1

Can anyone else give it a try on their end and see if they can re-produce my error? This library works fine with Blynk 1.0, my entire program works fine and is stable. However, like I mention above, if I try and add this working program statically to Blynk2.0 by adding the required template and device data along with a Blynk2.0 auth token it will not connect to the Blynk server. Also, as seen above, the Edgent example will not compile if you have

#include "esp_camera.h"

in your program.
