My ESP12-F was set on 38400 and working properly but suddenly I see some unreadable character so I decide to change the baudrate, I can send and receive AT command when my system baudrate is 23600 now. I set the baudrate again but same problem, the wifi is not working anymore. Maybe someone has an idea about why is this happening.

BR,

I found some more info and maybe sharing them will give some idea. The module default baud rate is 115200 but when this problem happen the baud rate automatically is changing from 115200 to 74,880, this happening during normal operation (some hard reset). At this moment the Wifi seems not working also.
