I bought 12 modules, I was lucky the first module I opened worked, so I used it to develop and test the code. Now I've come to use the rest, they were kept unopened in anti-static bags: 2 modules won't program, timed out when Arduino 1.8.13 tries to program the device. The program 5 modules but no connection to WiFi 5 modules works fine.
