Hello. I have the following problem. It’s being hard to use the Vext control. In my case, I’ve tested in two different devices (heltec esp32 LoRa V2) and I got same results. When Vext is On I get 3.3v aproximadetely. When Vext Off, I get 2.4v. I can’t measure 0v from the Vext pin.
The question is that I’m trying to use Vext for a buzzer, but it’s never turns off, cause always there is tension in this Vext pin.
Sorry about my english, hope someone can help me!
