Blynk 2.0 wifi provision

I am using esp32
I just change my wifi password whithout click the “reconfigured” botton on Blynk iot apps so how now how to I connect to the new router ?

WiFi credentials can be changed by using Blynk app, by resetting the device with a physical button, you can find the button pin number in the edgent settings.h

Ok thanks John

John I am using esp32 devkit

In this case you can configure a custom board in Settings.h
Go to the settings.h and scroll down to line 51 and you should see your custom board settings

Ok John thanks :relaxed::relaxed:
I will check thank you
