After i got my HC-12 modules i changed the baud rate to 115200 which went fine but then i changed the UART to FU4, after that i havent been able to enter an AT command and get a response. if i type in AT it only prints AT. i tried every baud rate to communicate with the module with no luck. anyone have any ideas?

Mode FU4 is incompatible with 115200.
It will only work at 1200 in that mode.
Try and reset the module using AT+DEFAULT sent to it at 1200 in set mode.
