New esp-01 board, no AT communication is happening
Posted: Tue Mar 30, 2021 4:54 pmHello, I just received my esp-01 from China and I'm using esp-01 usb adapter without any modifications or buttons to connect ground to gpio0. I selected esp board on arduinoide and using swrial monitor was hoping to test it, but nothing happened. No lines or words came and my board didnt respond to AT comands. Any idea what's the problem? Why cant i flash it. Does usb adapter has ch pd connected to vcc or do i need ir to do manualy ? And also do i need gpio0 put to ground or while trying to test it with AT comands it is not necessary?
