I have tested with the ESP CameraWebServer sketch first to make sure I could get the camera working, and it did succeed.

My plan is to have a video livestream of plants and hooking up a soil moister sensor and a DHT11 sensor.

I already got a working project with a “normal” ESP32 with the sensors mentioned above. Not I just want to move it to an ESP32 CAM and use the camera at the same time.

It might not be necessary to get the video stream working on the internet, locally would be fine, but having it online would be best.
The sensors however should still be working online.

I have access to my router, so port forwarding is possible if its necessary.

2

The error message you’re receive is is caused by ESP32 core v 3.x.x

The v3 version of the core now requires your sketch to contain:
#include <WiFi.h>
as well as #include <WiFiClient.h>

Previously, just having #include <WiFi.h> was sufficient, but now both are required.

The url for your video stream needs to be publicly resolvable for the Blynk app to be able to display it, so if you don’t have a static public IP address then you’ll need to use a DDNS service and run a DDNS updater on your local network, as well as opening the appropriate ports on your router and forwarding the inbound traffic to your ESP32CAM (which will need a static local IP address).

Pete.

3

Is that it? Nothing else I need to change?

4

Sounds bit like a hassle.

Could I combine the BlynkEdgent sketch and ESP CameraWebServer sketch so I just use Blynk with the sensors and when I’m home I just use my web browser to access the Webcam through it’s local IP address or would it give conflicts?

5

As I said, that’s the cause of the compiler error.

It won’t “give conflicts” it just won’t work unless the video stream is publicly resolvable. It doesn’t matter if your phone/tablet is connected to the same network as your ESP32, the app won’t be able to resolve the stream.

Pete.

6

I think you misunderstood.
So the sensors work with blynk as normal.

Then when I get home I connect to my WiFi, open my webbrowser, type 192.168.1.5 which is the esp32 ipadress to see the stream.

So it would work like two devices by running both the blynk sketch and the CameraWebServer sketch.

Because if I should be able to access it externally I should go to my router, find port forwarding, make a new rule, type 192.168.1.5 for the device, set it to TCP, use something like port 80.

Then I should be able to access it by typing something like http://11.222.333.4:80/

Am I completely wrong?

7

I assumed that you were talking about viewing the video stream in Blynk, via the video streaming widget.

If you’re wanting to run Blynk and a webserver on the same device then I’d probably avoid using the Blynk Edgent example.

Pete.

8

Yeah.
But now that I’m looking into it, it doesn’t seem that intimidating to set up to get the blynk video widget working.

9

Okay I tried added the two “includes” and I still get the same error. Also I don’t understand why that should fix all the GPIO errors I also have?

10

You don’t need to add two #includes as one is there already.
Where you add #include <WiFi.h> is important.

Pete.

11

okay I added only #include <WiFi.h>.

now I have this error:

To be 100% clear, your Edgent sketch ALREADY contained #include <WiFiClient.h> and you needed to add #include <WiFi.h> next to it.

Making a post that says “I added it” without saying WHERE you added it is of no use whatsoever when it comes to helping you resolve the problem.

You need to post your updated ConfigMode.h file if you want assistance with this issue.

Pete.

13

I added it above the line with #include <WiFiClient.h>

In the ConfigMode.h

If I roll back the ESP core version to before 3.0 it works fine without needed to add anything to the example sketch.

14

Okay if we skip that part for a moment. I got it working by rolling back to an early version.

I have a hard time understanding how to get the cam and BlynkEdgent sketch to work simultaneously.
Because when I first to copy paste the different elements from the CameraWebServer sketch into the BlynkEdgent sketch and adding the different “.h” files I just ending up with a sketch that is too big error.

So instead of having the whole CameraWebServer sketch merged into the blynk sketch, I want the absolute bare minimum to get a stream from the camera.

15

What functionality are you looking for with Blynk other than viewing the video stream via the Blynk video streaming widget?

The simplest solution is to have no Blynk code running on your ESP32 CAM at all, and configure it to provide a suitable video stream on the port of your choice.
Open the necessary ports and do the necessary port forwarding, and configure a DDNS service if needed, then point your Blynk widget at the video streams url.

Pete.

16

My wish is to use the ESB32 CAM as a weather station which also monitors soil humidity.
The reason I want to use BlynkEdgent is because I might need to change some values later on because its going to control a irrigation system, so its nice to have blynk Air available.
The camera is going to be used to monitor the progress and if the test is successful then use it to monitor if there is bugs in the flower.

17

I’d recommend getting one part working at a time before trying to combine everything into one sketch.

Pete.

18

Yeah I try to shave down the camera sketch. The blynk sketch is already working, so its just the camera.

19

I meant that I’d get a non-Blynk video sketch working, to stream the video to the Blynk video streaming widget.

Pete.

Okay after a lot of research and failed attempts I the camera plus “normal” blynk working:

/*
Next one is an include with wifi credentials.
This is what you need to do:

1. Create a file called "home_wifi_multi.h" in the same folder   OR   under a separate subfolder of the "libraries" folder of Arduino IDE. (You are creating a "fake" library really - I called it "MySettings"). 
2. Place the following text in the file:
#define SSID1 "replace with your wifi ssid"
#define PWD1 "replace your wifi password"
3. Save.

Should work then

**What I suspect to be wrong:

  1. WiFi.h, WebServer.h and WiFiClient is already implemented in Edgent inside ConfigMode.h.
  2. In the void Setup() there is something called cam.init(config); if I disabled that code I ESP32 will not get into bootloop, and will work with Blynk Edgent, but the webcam will not work.

Hopefully someone can figure out what my problem is.**
