Very helpful ❤️
Thanks Abhinav
In my device says to define blynk I'd and template id .how to fix it 😢 no idea with it
Check the blynk credentials and all headers must be inside the code folder as shown in the video
you can also go to the timestamp in the video description for your programming or connectivity error. you can also visit to our website page for it. www.smedehradun.com/2022/06/03/how-to-fix-errors-in-new-blynk/

sir my esp 32 keeps disconnecting while trying to connect my device to the blynk
Hi,
You can go through the alternate method to connect blynk 2.
Below video can guide you.

Hi. Want to ask. After i have connect to the wifi and blynk. Is it possible to delete the demo code and change to my own code
Yes you can.
I am geeting an error"old version of blynk library is in use. Please replace it with the new one" i also replace it with new library still the same error can u give solution for this
Hi Tejaswini,
You need to delete the old Blynk library from your Arduino IDE.
If you can update the blynk library as shown in video.
Try this, It will resolve this error. And if not resolved, then let me know. We will help you.
Hello i already installed the blynk library but it still keeps on showing compilation error :BlynkEdgent.h: No such file or directory
Hi,
If you have seen the video properly, then addon header files must be inside the programming folder.
It's already in the programming folder
What error you are getting?
the same error it always say no such file or directory
@@allansuarez4506 can you tell which video you are following? share the link.

It’s may be due to blynk token issue or network issue.
Please Check your blynk credentials and SSID and Password in your program.
thank help full!

It was awesome 👍
Thank you
hai, i already follow your instruction to clear trash in eeprom, but the notice on my arduino IDE is still there, it's written : "error for compiling ESP32 board' . I using ESP WROOM32 . Do you have solution for this? thanks.
This is not the eeprom error. There may possibility of syntax error in your code. So select the appropriate board & then compile. Library & header files must be included.
i'm using your demo code and i think its fine with the code. I also have selected the correct board because my board be able to execute previous program I put on. Full error code seen like this:

class BlynkWifi' has no member named 'notify' HELP ME OUT SIR PLEASE
This is the issue because of header files.
You need to have all the headers inside the programming folder. Also check that you have installed the latest blynk library. If you are not able to connect your baord to blynk using blynkedgent method Then you can another method to connect.
Below is the video that can show how you can-

if for esp8266 is the solution the same?
and can the code be used for esp8266?
Yes. You can also find the alternate solution to connect to the new blynk.

Must put all the header files inside the programming folder, change the credentials and follow all of the instructions shown in the video. I will work.
hello sir do you know why the coding say 'class BlynkWifi' has no member named 'email'? Hope you help me sir
There must be header file included in the programming folder. Plz watch the video properly and follow each and every step. Also add the latest blynk library in Arduino IDE.
This video will help you for it.

Welcome
Sir we getting error as header file that no such or directory: user_interface. h

Hi,
Follow every step, will resolve your problem.
If not, then let us know. But first go through the video.
when im uploading my own code the app is not working
Have you are using the blynkedgent function to connect with new blynk, then connect your board through the blynk IoT app otherwise you can use alternate method to connect.
See this video how to connect like old blynk.

Sir, why I don't have WiFi Blynk project after deleted old device data at blnyk because I want add new device data... do i need to buy another esp32? other than that, is there any other alternative? because before this I changed the new data device successfully when using the new esp
Yes. There is alternate to add new device manually.

Hi divanshu,
Which board you are using NodeMCU or ESP32 ?
How to connect esp8266 with blynk code and mpu6050 plese tell me sir
I have posted videos on different Methods to connect with new blynk.
In below video, I have shown the easiest way-

You need to add the MPU sensor code in the code and that’s it.
My Nodemcu prints unknown characters in the serial monitor
Select the exact baud rate for serial monitor as written in code.
Sir how to solve the problem of class BlynkWifi has no member named notify ,logevent in blynk2.0 do the video for these problem please sir
Update your blynk library with latest update & use events to notify.

Tq sir
while compling i am getting" blynkedgent. h :no such file or directory " error plz can u solve this problem
Hi,
Go through this video, This will resolve your problem.
th-cam.com/video/EPhY_hDozeo/w-d-xo.html
In the video, you ask us to replace #define BLYNK_DEVICE_NAME "Change it" with the text copied from the template firmware configuration section of the Blynk.Console. However, the variable there is no longer called "BLYNK_DEVICE_NAME". Now it is called "BLYNK_TEMPLATE_NAME". This causes an error that can be fixed easily by changing everything to ""BLYNK_DEVICE_NAME". Why are these two variables different? "Device_Name" implies it is the name of an individual device, however, you are clearly pasting in the name of the template.
This is recently changed that made by blynk.
So we just have to change the BLYNK_DEVICE_NAME to BLYNK_TEMPLATE_NAME?
Just copy paste the credentials from your blynk project to your code.
I followed all the steps and also clear the eeprom , serial monitor shows such logo but can't find it in wifi list

Disconnect all the connection from NodeMCU and the try it once again. If this will not work, then erase the eeprom of the esp8266 board and try again.
why nodemcu not blinking after i uploaded the code?
Hi,
I didn’t get you point.

It may due to token is different or may be there is some issue with token.
So check it or make new template & try to reconnect.

Sir how to find blynk version?
Now only new version is available in the play and App Store. Old version has been removed.
@@SMEDehradun means 1.0.1 or 0.1.1 ?
