Need Help With My Project

Hi there. I’m currently using an espressif esp32-WROOM-32 with Soft Access point. I’m also using IOS version 14.4.2. with the local esp32 server of 192.168.4.1 and my Blynk library version is 1.0.0-beta.3 . I’m encountering errors regarding Blynk that says


C:\Users\Dylan Anderton\OneDrive\Documents\Arduino\libraries\Blynk\src/Blynk/BlynkWidgetBase.h: In member function 'void BlynkWidgetBase::setMin(Args ...)':
C:\Users\Dylan Anderton\OneDrive\Documents\Arduino\libraries\Blynk\src/Blynk/BlynkWidgetBase.h:37:9: error: 'Blynk' was not declared in this scope
         Blynk.setProperty(mPin, "min", args...);
         ^

         Blynk.setProperty(mPin, "max", args...);

and here’s the code that I’m working with.

I urgently needs help and any help will be greatly appreciated. Thank you in advance.

@completenewbie I’ve deleted your “dylankeren” p[ersona and the topics that you spammed the forum with.
Please do not create another persona, otherwise your IP address and email address will be blocked.

So, on your 4th topic, you’ve realised that following the forum rules, providing the required information, and correctly formatting your code, will get you some answers…

I’d suggest that you switch to the current stable release, which is 0.6.1

If it ships with a soft access point then I think you can expect that to be overwritten when you upload your first sketch.

Pete.
