Unable to connect my esp32 board with Blynk
Please help me with this.
Impossible, without more info, such as the sketch that you’ve uploaded to your ESP32.
Don’t forget to put triple backticks at the beginning and end of your sketch when you post it.
Triple backticks look like this:
```
I’d suggest posting your serial monitor output too, also with triple backticks at the beginning and end.

You should start with a very basic sketch first just to make sure everything is working properly.
also, posting your serial monitor output would be very useful as @PeteKnight suggested.
As I said earlier, you should copy the text from your serial monitor and paste it between triple backticks, rather than posting screenshots.
Are you 100% sure that the SSID and WiFi password are correct (both are case sensitive).
Do you have anything connected to pins 1 or 3 on your ESP32 ?
Pete.
15:50:54.827 -> connecting to MUSK
Apologies for the inconvenience. The above is getting printed.
And I am positive that the SSID and WiFi password are correct, case sensitivity considered. Also, there is no connection to pin 1 and pin3.
Shifani.
In that case, I’d do as @John93 suggests and try a basic Blynk sketch for the ESP32 and get that working first.
In your screenshot you were getting some additional characters between your timestamp and the readable message. Have you edited these out in the text you pasted above?
These characters aren’t normal, and would indicate a problem to me.
Pete.
