ESP-01 Not working with V Pin


I have an issue. I can get the Blynk 2.0 to work and the reactions on the web dashboard and the mobile dashboard are in sync.

I think my issue might be that pinouts need to be set up in the settings.h Does anyone have a setup I could try?

Or is there something else I am missing?

Have you gone through the “add device” provisioning process in the app?
Was it successful?
Does the device show as being online in the app and the web console?

Do you have an adapter to allow you to view the serial output of the ESP-01? If not then it will be very difficult to diagnose what is happening in terms of the connection, if it’s not provisioning or connecting properly.

Personally, I don’t think I’d use the Edgent examples with an ESP-01. Instead I’d use the static provisioning process.


Yes, I did “add device” in the app and it is showing online in the app and web console.

I do have an adaptor that should show the serial output.

Could you please expand on the static provisioning.

If your device is connecting and online then are you trying to control a GPIO via a digitalWrite command in your code, triggered by a BLYNK_WRITE(vPin) command?
If so, do you have a corresponding PinMode statement in your void setup?

There really aren’t enough pins available on the ESP-01 to use the pins declared in Settings.h properly. If the pins declared in Settings.h are conflicting with the pins you are trying to control yourself then maybe define the LED and Button pins in Settings.h as GPIO 15 and 16
